+
+\section{Introduction}
+\MH/ is a very powerful message handling system that runs under the \unix/
+operating system.
+One of the many features which \MH/ offers is an interface to the UCI BBoards
+facility.
+This facility permits the efficient distribution of interest group messages
+on a single host, a group of hosts under a single administration, and the
+ARPA Internet community.
+
+Described simply, a interest group is composed of a number of subscribers
+with a common interest.
+These subscribers post mail to a single address, known as a
+{\it distribution} address.
+From this distribution address, a copy of the message is sent to each
+subscriber.
+Each group has a {\it moderator},
+which is the person that runs the the group.
+This moderator can usually be reached at a special address,
+known as a {\it request} address.
+Usually, the responsibilities of the moderator are quite simple,
+since the mail system handles the distribution to subscribers automatically.
+In some cases, the interest group,
+instead of being distributed directly to its subscribers,
+is put into a {\it digest} format by the moderator and then sent to the
+subscribers.
+Although this requires more work on the part of the moderator,
+such groups tend to be better organized.
+
+Unfortunately, there are a few problems with the scheme outlined above.
+First, if two users on the same host subscribe to the same interest group,
+two copies of the message get delivered.
+This is wasteful of both processor and disk resources.
+
+Second,
+some of these groups carry a lot of traffic.
+Although subscription to an group does indicate interest on the part of a
+subscriber,
+it is usually not interesting to get $50$ messages or so delivered to 
+the user's private maildrop each day,
+interspersed with {\it personal} mail,
+that is likely to be of a much more important and timely nature.
+
+Third, if a subscriber on the distribution list for a group becomes ``bad''
+somehow,
+the originator of the message and not the moderator of the group is notified.
+It is not uncommon for a large list to have $10$ or so bogus addresses present.
+This results in the originator being flooded with ``error messages'' from
+mailers across the ARPA Internet stating that a given address on the list was
+bad.
+Needless to say,
+the originator usually could not care less if the bogus addresses got a copy
+of the message or not.
+The originator is merely interested in posting a message to the group at large.
+Furthermore, the moderator of the group does care if there are bogus
+addresses on the list,
+but ironically does not receive notification.
+
+To solve all of these problems,
+the UCI BBoards facility introduces a new entity into the picture:
+all interest group mail is handled by a special component of the mail system.
+The distribution address maps to a special {\it channel} that performs
+several actions.
+First, if local delivery is to be performed,
+then a copy of the message is placed in a global maildrop for the interest
+group with a timestamp and a unique number.
+Local users can read messages posted for the interest group by reading the
+file.
+Second, if further distribution is to take place,
+a copy of the message is sent to the distribution address in such a way that
+if any of the addresses are bogus,
+the failure notice is sent to the maintainer of the group and not the
+originator.
+
+This scheme has several advantages:
+First, messages delivered to the host are processed and saved once
+in a globally accessible area.
+The UCI BBoards facility supports software which allows a user to query the
+interest group for new messages and to read those messages in the \MH/-style.
+Second, once a host subscribes to an interest group,
+a user can add or remove him/herself from the list without contacting the
+moderator.
+Third, a hierarchical distribution scheme can be constructed to further
+reduce the amount of message traffic.
+Fourth, errors are prevented from propagating.
+When an address on the distribution list goes bad,
+the request address immediately responsible for the address is notified.
+Usually, this is the local PostMaster and not the group moderator.
+
+In addition to solving the problems outlined above,
+the UCI BBoards facility supports several other capabilities.
+BBoards may be automatically archived in order to conserve disk space and
+reduce processing time when reading them.
+
+Special alias files may be generated which allow the \MH/ user to shorten
+address type-in.
+For example, instead of sending to address@hidden,
+a user of \MH/ usually sends to \eg{SF-Lovers} and the \MH/ aliasing
+facility automatically makes the appropriate expansion in the headers of the
+outgoing message.
+Hence, one need only know the name of a interest group and not its address.
+
+Finally, the UCI BBoards facility supports {\it private} interest groups
+using the \unix/ group access mechanism.
+This allows a group of people on the same or different machines to conduct a
+private discussion.
+
+The practical upshot of all this is that the UCI BBoards facility automates
+the vast majority of BBoards handling from the point of view of both the
+PostMaster and the user.
+
+\section{BBoard Handling}
+Usually the term {\it BBoard} is used interchangeably with the terms
+{\it discussion group} and {\it interest group}.
+This is true of the discussion that follows.
+
+The messages for a BBoard delivered locally are kept in the same format as
+a maildrop.%
+\nfootnote{Actually,
+your site might be running with all BBoards kept on a single host.
+\MH/ supports the remote access of BBoards using a modified version of the
+ARPA Post Office Protocol (POP).
+This has the advantage that it saves a lot of disk space,
+and incurs only a modest performance penalty.}
+Unlike the user's private maildrop however,
+the \pgm{inc} program is not run to incorporate new BBoard messages into
+the user's \MH/ \eg{+inbox} folder.
+The programs which are used will be discussed momentarily.
+
+Each message in a BBoard maildrop has a unique number and a timestamp.
+The number, called the {\it BBoard-ID}, is always ascending.
+The BBoard-ID of a message should {\bf NOT} be confused with the message
+number of a message, which can change as messages are removed from the BBoard.
+The BBoard-ID is a value which is unique for every message delivered locally
+to the BBoard.
+
+To read BBoards, the \MH/ user invokes \pgm{bbc}.
+The \pgm{bbc} program has several switches to direct it's action.
+The \switch{topics} switch to \pgm{bbc} tells the \MH/ user about the
+status of a BBoard.
+The \switch{check} switch to \pgm{bbc} lets the \MH/ user check on the
+activity of a BBoard.
+The \switch{read} switch to \pgm{bbc} invokes the \pgm{msh} program on the
+BBoard.
+\pgm{msh} is a monolithic program which contains most of the functionality of
+\MH/ in a single program.
+These commands are now discussed in greater detail.
+
+\subsection{BBoard status}
+The \switch{topics} option to the \pgm{bbc} program can be used to report
+information about a BBoard that does not pertain to the user's reading habits.
+If the \MH/ users types \example bbc\ -topics\endexample
+then \pgm{bbc} will list the following information for all BBoards received
+on the host:
+\smallskip
+{\advance\leftskip by\parindent
+\item{$\bullet$} the official name of the BBoard
+\item{$\bullet$} the number of messages delivered to the BBoard
+(but not necessarily present)
+\item{$\bullet$} the date and time of the last message delivered to the BBoard
+\medskip}
+\noindent
+In addition to \switch{topics},
+if the \switch{verbose} option is given to \pgm{bbc},
+then more information is listed:
+\smallskip
+{\advance\leftskip by\parindent
+\item{$\bullet$} any aliases the BBoard is known as
+\item{$\bullet$} the local leaders of the BBoard
+\item{$\bullet$} the file that the BBoard is locally delivered to
+\item{$\bullet$} the ``global'' distribution address
+\item{$\bullet$} the ``global'' request address
+\item{$\bullet$} the host that distributes the BBoard to the local host
+\item{$\bullet$} the addresses to which this host distributes
+\item{$\bullet$} miscellaneous information (presently only archiving status)
+\medskip}
+\noindent
+Naturally, \pgm{bbc} can be invoked with the \switch{topics} option and one or
+more BBoard names listed on its command line.
+For example \example bbc\ -topics\ unix-wizards\endexample is completely
+acceptable~---~it tells \pgm{bbc} to report the status of the BBoard
+\eg{unix-wizards}.
+
+\subsection{BBoard checking}
+The \switch{check} option to the \pgm{bbc} program can be used to check for
+new BBoard messages in a synchronous fashion
+(i.e., when you specifically ask for it).
+The \MH/ users types \example bbc\ -check\endexample and \pgm{bbc} consults
+the profile entry for \eg{bboards:} in the user's \profile/ file.
+For each BBoard listed,
+\pgm{bbc} prints one of several messages depending on the status of both the
+BBoard and the user's reading habits
+(for example, in the case of the mythical BBoard \eg{foo\/}):
+\smallskip
+{\advance\leftskip by\parindent
+\item{1.} \eg{foo -- n items unseen}\hbreak
+This message indicates items in the BBoard have not been seen by the user.
+When \pgm{bbc} is invoked with the \eg{quiet} switch,
+this is the only informative message that \pgm{bbc} will print out.
+Users of \MH/ usually put \example bbc\ -check\ -quiet\endexample
+in their \file{\$HOME/.login} file.
+
+\item{2.} \eg{foo -- empty}\hbreak
+The BBoard is empty.
+
+\item{3.} \eg{foo -- n items (none seen)}\hbreak
+The BBoard has $n$ items in it, but the user hasn't seen any.
+
+\item{4.} \eg{foo -- n items (all seen)}\hbreak
+The BBoard is non-empty, and the user has seen everything in it.
+
+\item{5.} \eg{foo -- n items seen out of m}\hbreak
+The BBoard has at most $m-n$ items that the user has not seen.
+\medskip}
+\noindent
+It is important to note that \pgm{bbc} performs its calculations on
+BBoard-ID:s and not the messages actually present in a BBoard.
+This means that the numbers given by \pgm{bbc} are maximal end-points.
+When \pgm{bbc} says $n$, \pgm{bbc} means ``at most $n$''.
+
+Naturally, \pgm{bbc} can be invoked with the \switch{check} option and one or
+more BBoards listed on its command line.
+For example \example bbc\ -check\ info-c\ poli-sci\endexample is completely
+acceptable~---~it tells \pgm{bbc} to check on the BBoards \eg{info-c} and
+\eg{poli-sci} only.
+
+There are two ways to check for new BBoard messages in an asynchronous fashion:
+using the \pgm{CShell} variable \file{\$mail} and running the \pgm{useto}
+program.
+
+\subsubsection{Asynchronous Checking with the CShell}
+The \pgm{CShell} has a variable called \file{\$mail}.
+This variable can contain one or more words.
+Each word should be a filename where the shell should check for new mail.
+The check is performed after a specified time interval has elapsed just
+before the shell would prompt the user.
+
+If the first word of \file{\$mail} is a number,
+then this number specifies a different checking interval, in seconds,
+than the default, which is 10 minutes.
+
+Whenever the time interval elapses and the shell is ready to prompt the user,
+the shell looks at the file and decides if new messages have arrived.
+If so, it says \example You have new mail.\endexample
+if only one file is present in \file{\$mail}.
+Otherwise,
+if more than one file is present in \file{\$mail},
+then the shell says \example New mail in foo.\endexample whenever there is new
+mail in the file called \eg{foo}.
+
+To find out what file is associated with a BBoard, say \eg{info-unix},
+the \MH/ user types \example bbc\ -topics\ -verbose\ info-unix\endexample
+Usually the local file for a BBoard has an extension of \file{.mbox}.
+
+\subsubsection{Asynchronous Checking with Useto}
+In contrast to using the \file{\$mail} variable in the \pgm{CShell},
+the \MH/ user might employ \pgm{useto} instead.%
+\nfootnote{Not all sites have \pgm{useto};
+contact the same people who supplied \MH/ to get a copy.}
+The \pgm{useto} program is a continuous update display that prints information
+on the status line of your terminal.
+Needless to say,
+your terminal must support a status line in order to run \pgm{useto}.
+Not all terminals have this capability,
+but for those that do it's usually well worth the effort to run \pgm{useto}.
+
+For example, users of \MH/  could put
+\example
+    useto\ -bepf\ \'tcp-ip\ sftp\'\ %
+       \'\%D\ \%M\ \%d\ \%h:\%m\%z\%b\ \%n.tty\%t:\%l1\'%
+\endexample
+in their \file{\$HOME/.login} file.
+This command line to \pgm{useto} says to inform the user of
+\smallskip
+{\advance\leftskip by\parindent
+\item{$\bullet$} the current date and time
+\item{$\bullet$} new mail for the user
+\item{$\bullet$} new messages for the BBoards \eg{tcp-ip} and \eg{sftp}
+\item{$\bullet$} the name of the host and tty that the user is logged in on
+\item{$\bullet$} the 5--minute load average of that host
+\smallskip}
+
+The \pgm{useto} program is really quite amusing and useful.%
+\nfootnote{To be honest,
+the author considers computing environments without \pgm{useto}
+to be less than adequate.}
+
+\subsection{BBoard reading}
+If \pgm{bbc} is not given either the \switch{check} or \switch{topics} option,
+the \pgm{bbc} program reads BBoard messages.
+For each BBoard listed in the \MH/ user's profile entry for \eg{bboards:},
+\pgm{bbc} checks to see if there is unread mail.
+If so, \pgm{bbc} starts \pgm{msh} on the BBoard,
+telling \pgm{msh} which messages haven't been seen.%
+\nfootnote{If the \switch{verbose} option is given to \pgm{bbc},
+then \pgm{bbc} will start \pgm{msh} on the BBoard regardless of whether there
+are unseen messages there.}
+
+When \pgm{msh} starts it identifies the BBoard being read and indicates how
+many messages are present and how many the user has read.
+Usually, in the user's \MH/ profile,
+the user has the entry \example msh:\ -scan\endexample
+This says that when \pgm{msh} starts,
+it should print a {\it scan listing} of the messages which the user
+hasn't seen yet.
+
+The \pgm{msh} program now prompts the user for \MH/ commands.
+The user may type most of the normal \MH/ command.
+The syntax and semantics of the commands typed to \pgm{msh} are identical
+to their \MH/ counterparts.
+For example, to reply to a message on the BBoard,
+the \MH/ user types \eg{repl};
+other \MH/ commands likewise may be applied to BBoard messages.
+In cases where the nature of \pgm{msh} would be inconsistent
+(e.g., specifying a \arg{+folder} with some commands),
+\pgm{msh} will duly inform the user.
+In addition to supporting most \MH/ commands,
+\pgm{msh} also has a \eg{help} command which gives a brief overview.
+
+The only command that behaves entirely differently in \pgm{msh} is the
+\eg{mark} command when given no arguments.
+The \pgm{msh} program maintains a special sequence, \eg{unseen},
+which it uses to keep track of the messages you've seen.
+If the \eg{mark} command is given without any arguments,
+then \pgm{msh} will interpret it as
+\example mark\ -sequence\ unseen\ -delete\ -nozero\ all\endexample
+Hence, to discard all of the messages in the current BBoard being read,
+the \MH/ user types \eg{mark} which says to remove all messages from sequence
+called \eg{unseen}.
+
+To leave \pgm{msh} use the \eg{quit} command.
+This tells \pgm{msh} to terminate and \pgm{bbc} to go to the next BBoard.
+Instead, if the user types EOT (usually CTRL-D),
+then \pgm{bbc} will exit as well,
+updating whatever information was appropriate.
+
+\section{Current BBoards}
+There are many, many active interest groups.
+Consult the BBoard called \eg{list-of-lists} for a comprehensive description.

+\noindent
+As discussed earlier,
+to find out about all of the BBoards that the local host subscribes to,
+the \MH/ users types \example bbc\ -topics\endexample
+
+\section{More on BBoards}
+Finally, here are a few more operational details:
+
+\subsection{Creating a BBoard}
+Contact the PostMaster at your host to have a BBoard created.
+Be sure to indicate its status (public or private)
+and scope (where distribution should occur).
+
+\subsection{Subscribing to a BBoard}
+If your local host already receives an interest group,
+then simply add the name of the BBoard to the \eg{bboards:} entry in your
+\MH/ profile.
+If not, ask the PostMaster to create the BBoard and contact the global
+request address for you.
+
+\subsection{BBoard Archives}
+BBoard messages are automatically archived on a weekly basis.
+Usually, this results in messages older than 12 days being moved to an
+{\it archive} area.
+To read the archives for a BBoard, the \switch{archive} option is used.
+For example, \example bbc\ -archive\ telecom\endexample
+tells \pgm{bbc} to invoke \pgm{msh} on the archives for the \eg{telecom}
+BBoard.
+
+Note that the archives may not be present for all BBoards on a given host;
+also note that the archives may be periodically moved to tape and expunged
+from the system.
+Contact your local PostMaster for the details.
+
+\subsection{BBoard Addresses}
+Each BBoard has associated with it 4 addresses
+(for example, in the case of the mythical BBoard \eg{foo\/}):
+\smallskip
+{\advance\leftskip by\parindent
+\item{\tx foo} The global distribution list\hbreak
+If you post a message addressed to {\tx foo} then the message is distributed
+to everyone who subscribes to \eg{foo}.
+
+\item{\tx dist-foo} The local distribution list\hbreak
+If you post a message addressed to {\tx dist-foo} then the message is
+distributed to the local BBoard for \eg{foo}
+and to any sites which the local system distributes to.
+
+\item{\tx foo-request} The global moderator\hbreak
+If you post a message addressed to {\tx foo-request} then the message is
+sent to the moderator for the entire interest group called \eg{foo}.
+
+\item{\tx local-foo-request} The local moderator\hbreak
+If you post a message addressed to {\tx local-foo-request} then the message is
+sent to the person responsible for the BBoard \eg{foo} on the local system.
+\medskip}
+\noindent
+These addresses are defined by the \MH/ alias facility.
+Users of the BBoards facility who do not use \MH/ may not be able to make use
+of them.
+
+\subsection{Leading a BBoard}
+Except for special circumstances, this task is wholly automated.
+For more information though,
+see the manual entries for \man bbl(1) and \man bbleaders(8).
+
+\section{Extra for Experts}
+Some clever \MH/ users might ask why BBoards aren't kept as folders instead
+of \pgm{pack}'d files.
+This is a good question.
+Perhaps some future release of \MH/ and the UCI BBoards facility will treat
+BBoards as a variant of read-only folders.
+
+The problem with \pgm{msh}, of course, is that it's a monolithic program,
+and although it does support input/output redirection and a few other
+primitive shell-like properties, it's still not the \pgm{CShell}.

+\title{MH for Beginners}
+\author{Mary Hegardt \and Tim Morgan}
+\maketitle
+
+This document is intended to be an introduction for new users to the
+\MH/ mail system. For more detailed information, users will want to
+read the document called {\sl The Rand MH Message Handling System:
+User's Manual\/} by Marshall~T. Rose and John~L. Romine. It is available
+for Xeroxing in suite CS408.
+\footnote{This document is specific to the environment
+at the ICS department of U.~C.~Irvine.  For a more general document,
+see {\sl The Rand MH Message Handling System: Tutorial\/}.}
+
+\section{Using Electronic Mail}
+
+Electronic mail (e-mail) is a quick, convenient way to send a message
+to another person (or persons).  The message recipient can read and
+reply to the message at his convenience. E-mail is much faster than
+a paper memo and avoids inconveniences associated with the telephone
+such as unwanted interruptions and ``phone tag.''
+
+At UCI, one can send e-mail to people within the ICS department, people
+in other units on campus, and to people at some other institutions
+off campus (usually other universities).
+
+An electronic mail message consists of two parts: the headers and the
+body.  The body comes after the headers and consists of the ``message'':
+whatever the sender types in. The headers are the lines at the top
+of the message including the subject and addresses of the people
+to whom the message is addressed.  It is similar to the top lines
+of a memo: {\tt To:}, {\tt From:}, {\tt Subject:}, and so on.  The headers
+are separated from the body by a blank line. As in memos, the people
+listed in the {\tt Cc:}\ field are not intended to be the primary recipients 
+of the message. The message is for their information only, and they
+are not expected to reply.
+
+
+E-mail is also useful for discussions among groups of people.  This
+``bboards'' (electronic bulletin boards) facility will be discussed later.
+
+An electronic mail address looks like ``{\it name\/address@hidden site\/}''.
+The {\it name\/} is
+a person's ``mail handle'' --- usually his first initial followed by his
+last name.   For example, Mary Hegardt's mail handle is ``mhegardt''.
+The {\it site\/} is the system where the addressee receives mail.  Within
+the ICS Department, you need only know the person's mail handle;
+the mail system will automatically fill in the ``{\tt @}{\it site\/}'' part.
+
+\section{Why MH ?}
+
+The \MH/ system is very different from most mail user agents.  Instead of 
+running one large program which handles all mail functions and keeps
+messages in one large file, \MH/ is a collection of smaller 
+single-purpose programs used to manipulate mail messages
+which are kept in individual files.  \MH/ may seem to be more complicated
+or harder to use than other mail systems (MM, for example), but  
+\MH/ has been designed to allow
+you to take full advantage of existing {\sc Unix}\footnote{{\sc Unix} is 
+a trademark of AT\&T Bell Laboratories} commands and programs
+in connection with mail messages.
+For example, you can use your usual text editor, spelling program, and
+printer commands on individual messages.  
+
+
+\section{The Basics}
+
+The first time you use an \MH/ command (probably {\it inc\/}), 
+\MH/ will create a directory called ``Mail'' in your home (login) directory. 
All
+your mail will be stored in directories beneath this one.  It will also
+create a file in your home directory called \verb|.mh_profile|.  It is
+a file that allows you to tailor your \MH/ environment.  We'll discuss
+this more later.  
+
+
+\subsection{Reading Mail}
+
+When someone sends a mail message to you, it is delivered to a file
+called your ``mail drop'' file.  When you are ready to read your mail,
+you have to incorporate (or ``inc'') your mail messages from the mail
+drop area into your account.
+
+Everytime you log in to your {\sc Unix} account, you will be told if you
+have new mail messages.  When you are ready to read them, type \verb|inc|.
+The {\it inc\/} program will copy your mail into your ``inbox'' and generate
+a ``scan'' listing of the new messages. For example,
+
+\begin{scriptsize}
+\begin{verbatim}
+4.2 BSD UNIX #116: Mon Jul 15 14:03:21 PDT 1985
+You have new ZOTnet mail, type "inc" (or mail)
+
+TERM = (dm1520)
+
+% inc

+   9  11/18 1346-EDT address@hidden           Have we got a problem?
+\end{verbatim}
+\end{scriptsize}
+
+This is what a typical ``inc'' session for the Postmaster looks like.  
+{\it Inc\/} copies my mail into my ``inbox'' folder, assigns a unique number to
+each message, and scans them for me.  The numbers allow you to refer
+to each message individually.  After the message number, you see the
+date and time the message was sent, the name of the sender, and the
+subject of the message. The ``current'' message is indicated by a 
+``{\tt +}'' sign. To read it, type ``{\tt show}'':
+
+\begin{scriptsize}
+\begin{verbatim}
+% show
+
+   (Message inbox:1)
+   Received: from localhost by UCI.EDU id a005369; 29 Oct 85 17:32 PST
+   To: address@hidden
+   Subject: new bboard!
+   Date: 29 Oct 85 17:32:24 PST (Tue)
+   From: Tim Morgan <address@hidden>
+   
+   Please add us to the unix-sw list.  Also, if RAJ hasn't mentioned it,
+   and if it still exists, we should get on the Astronomy bboard.
+
+   Tim
+\end{verbatim}
+\end{scriptsize}
+
+If the message is
+longer than one screenful, you will see the word ``more'' at the bottom
+of the screen.  When you are ready to see ``more'' of the message,
+press the \fbox{space bar} to see another screenful, or press the 
+\fbox{return} key to see just one more line.
+
+To see the next message, you could type a couple of different commands:
+
+
+\oneline{\% next}
+or
+\oneline{\% show next}
+or
+\oneline{\% show 2}
+
+All of these commands would have the same effect: to type out the next message
+in the list.  The most efficient thing to do is to type ``{\tt next}''.  When
+You do that, message number 2 will be shown and become the ``current message''.
+
+\begin{footnotesize}
+\begin{verbatim}
+% next
+
+(Message inbox:2)
+Received: from UCI-20B by UCI-ICSA id aa01222; 12 Nov 85 0:23 PST
+Date: 12 Nov 1985 0016-PST
+From: address@hidden
+Subject: CP6 from the 20s
+To: address@hidden
+cc: address@hidden
+
+What is (will be) the prescribed method of addressing for sending
+CP6 mail from the 20s?  They dont seem to know about @CF, @UCICP6,
+but "Name_Name%UCICP6"@ICSA seems to fly.
+
+       dana
+\end{verbatim}
+\end{footnotesize}
+
+\subsection{Selecting Messages}
+
+As you have seen, messages can be referred to by their message numbers.
+Some \MH/ commands, such as {\it show,} can act upon more than one
+message at a time. A range of messages can be specified using the
+form ``{\it name1-name2\/}'' where {\it name\/} is a message number or
+one of the reserved message names described below:
+
+\bigskip
+
+\def\titem[#1]{\par\noindent\hbox to .5in{\hfil\it #1\/}\qquad}
+
+\titem[cur] The current message (the last one that was handled)
+\titem[next] The next message (same as ${\it cur\/} + 1$)
+\titem[prev] The previous message (${\it cur\/} - 1$)
+\titem[first] The first message in the current folder
+\titem[last] The last message in the folder
+\titem[all] All messages ($\it first-last$)
+
+\bigskip
+
+If you do not name a specific message, the command will act upon
+the ``current message''.
+
+\subsection{Sending Messages}
+
+A mail message consists of two parts: the headers and the body.  The
+headers are the lines at the top of the message that say ``{\tt To:}''
+and so on.  The body is the actual text of the message (what you
+want to say).  To send someone a message, you start with the
+{\it comp\/} command.  This will start up an editor called {\it prompter\/}
+that will prompt you to fill in the headers. You should type the
+requested information for that header or a \fbox{return} to omit it.  
+You should end the message by typing control-D (press down the key
+marked \fbox{ctrl} and strike the D key) at the beginning of a new
+line.  Here's an example:
+
+\begin{verbatim}
+       % comp
+       To: morgan, raj
+       Cc: 
+       Subject: Lunch
+       ---------
+       Where are we going for lunch today ?  
+
+       Mary
+       <control-D>
+       --------
+       What now ?  send
+\end{verbatim}
+
+At the ``\verb|What now ?|'' prompt you can type a {\tt?} to see 
+what commands you can type next.
+One of the most useful options at this point is to edit the draft
+of the message to correct any mistakes.  To do this you type:
+
+\oneline{What now ?  edit vi}
+
+This will put you in the {\it vi\/} editor to edit the message.  If you use
+{\it emacs\/} or any other editor, just type ``edit emacs'' or whatever.
+When you have finished editing, just exit the editor as you would 
+normally.  You will then get another ``\verb|What now ?|'' prompt. Here are 
some
+of the ``What now'' options:
+
+\bigskip
+
+\begingroup
+\def\titem[#1]{\par\hangafter=1\hangindent=1.4in\noindent
+       \hbox to\hangindent{\hfil#1\qquad}\ignorespaces}
+
+\titem[\tt edit \it editor\/] Edit the message using the specified
+                               editor.  When you exit, you will be
+                               back at \verb|What now|.
+
+\titem[\tt list] Shows the message you just typed
+
+\titem[\tt whom -check] Verifies that the addresses you have
+                               used are valid as far as our system
+                               can tell
+
+\titem[\tt send] Sends the message to the recipients
+
+\titem[\tt push] Sends the message in the background
+
+\titem[\tt quit] Quits without sending the message.
+                               Saves the text of the message as
+                               a ``draft''. Type \verb|comp -use| to
+                               get back to that draft later.
+
+\titem[\tt quit -delete] Quit, throwing away the draft
+\endgroup
+
+\bigskip
+
+Make sure you are happy with your message before typing \verb|send|.  There
+is no way to recall a message once it has been sent.
+
+\subsection{Replying to Messages}
+
+To reply to the current message type {\it repl.}  When you do this, 
+the reply headers will be printed out and you will be put in the prompter
+editor to type in your reply text. When you are replying  to a message,
+the name of the sender of the original message will appear in the
+``To:'' field.  Any people on the ``To:'' or ``Cc:'' lists will also
+be copied on your reply message. As with {\it comp,} when you have
+finished, type control-D and \verb|send| (or whatever) at \verb|What now ?|.
+
+\subsection{Forwarding Messages}
+
+If you receive a particularly interesting message and can't resist
+sharing it with others, you can forward it using the {\it forw\/}
+command.  You will be prompted to fill in the headers (the address
+to which the message is to be forwarded, etc.). When you have done this,
+you will see the text of the message which you are forwarding and will be
+given the opportunity to add some enlightening text to the message.
+Exit with control-D and do whatever feels good at the \verb|What now ?|
+prompt.
+
+\subsection{The Advanced Features}
+
+You will probably want to master the beginning \MH/ concepts before you
+tackle the following\dots
+
+\subsection{Folders}
+
+Folders are really just directories for storing mail messages in an
+organized way.   To store a message in a folder named
+``inbox'', type:
+
+\oneline{\% refile 5 +inventory}
+
+If the folder doesn't exist yet, you will be asked if it should be created.
+To access messages in another folder, you can change your current
+folder from ``inbox'' to something else.  If you want to look at all
+the messages pertaining to the inventory, you type:
+
+\oneline{\% folder +inventory}
+
+and now you use {\it scan,} {\it show,} etc., to manipulate the messages
+in that folder.
+To change back to inbox, type:
+
+\oneline{\% folder +inbox}
+
+Using the {\it inc\/} command will change your current folder to be the
+``inbox'' automatically.
+       
+\section{Mailing files}
+
+Mailing files is usually not a good idea, especially for large files.  
+The mail system was never designed for moving big files. You
+can use the {\it cp\/} file to move the file to another account much more
+efficiently:
+
+\oneline{\% cp \char`\~frated/desired-file \char`\~./newfile}
+
+This will copy the file from frated's account to the current directory and
+call it ``newfile''. 
+
+You can also copy files across the network using {\it rcp\/}:
+
+\oneline{\% rcp icsd:frated/desired-file ./newfile}
+
+This copies frated's file on the system icsd to the current directory.
+
+If you {\it really\/} have to mail a file, you use the {\it mhmail\/} program.
+To mail a file ``myfile'' to another user ``frated'', with ``MyFile'' as
+the subject type:
+
+\oneline{\% mhmail frated -subject MyFile < myfile}
+
+
+\section{Searching for messages}
+
+The {\it pick\/} program allows you to search your inbox (or any other)
+folder to find messages which contain a certain word.  If you want to 
+list all messages from Smith you can type:
+
+\oneline{\% pick -from smith -list}
+
+and it will list the numbers of all messages from Smith that are in the
+current folder.  You can {\it pick\/} messages according to any of the
+headers ({\tt -to -from -subj -cc {\rm or} -date}) or just search all the
+messages for a given word ({\tt -search}).
+
+\section{The MH Profile}
+
+Each \MH/ user has a file in his directory called \verb|.mh_profile|.  This
+file contains a list of user-specified default options for \MH/ programs.
+The only required
+entry is the name of your \MH/
+directory:
+
+\oneline{Path: Mail}
+or
+\oneline{Path: mhbox}
+
+To make a change to your \verb|.mh_profile|, you edit the file and add a
+line for the applicable program.  For example, if you would like to use {\it
+vi\/} instead of {\it prompter\/} as your initial editor when composing
+messages, you would add this line to your \verb|.mh_profile|:
+
+\oneline{comp: -editor vi}
+
+or, if you want to have a format file for {\it scan\/} to use, you should
+have:
+
+\oneline{scan: -form {\it formatfile}}
+
+Almost all of the \MH/ programs have options that can be set using the
+\verb|.mh_profile|. You should consult the {\sl MH User's Manual\/}
+for more information about this.
+
+Many people will want to add a signature line to their \verb|.mh_profile|.
+This line  will appear as your signature on the From: line in messages
+you send. It looks like this:
+
+\oneline{Signature: John Q. Public}
+
+
+Occasionally people express an interest in getting rid of some of the
+header lines in their mail messages.  They don't want to see the
+``Received from'', ``Via'' information, or some other header.  It
+is possible to prevent these and other annoying headers from being
+displayed by changing your {\it show\/} processor to be {\it mhless.}
+To do this you must add this line 
+
+\oneline{showproc: mhless}
+
+to your \verb|.mh_profile|. You also must create a file 
+called ``.mhlessrc'' containing the words which
+appear at the beginning of the lines you don't want to see.
+ 
+The typical ``.mhlessrc'' file will look like this:
+\begin{verbatim}
+       Received
+       Via
+       BB-Posted
+       Return-Path
+\end{verbatim}
+
+The ``.mhlessrc'' file must be in your home directory.
+
+
+\section{BBoards}
+
+Electronic bulletin boards (BBoards) are a convenient way for a group
+of people to discuss a particular topic.  Messages are sent to
+an address where they can be read and replied to by all interested
+parties. In the ICS department we have some ``local'' BBoards which
+involve only people in the department.  We also subscribe to many
+nationally distributed BBoards.  BBoards are read using the {\it bbc\/}
+program which will allow you to read the messages with
+an \MH/-like interface. 
+
+One very important BBoard is ``system''.
+It contains vital news about changes in software, system
+downtime, new programs, and other information useful to all users.
+
+To read a BBoard, you type ``\verb|bbc| {\it BBoard\_name\/}''. The {\it
+bbc\/} program will check to see if there are new messages in the named
+BBoard and if there are, it will start up {\it msh\/} so you can read them.
+The {\it msh\/} program allows you to use regular \MH/ commands when reading
+BBoards. Type ``{\tt show}'' to see the current message, ``{\tt next}'' to
+see the next message, and so on.  Type ``{\tt quit}'' to quit reading the
+current BBoard. If you have named more than one BBoard on the command line
+or in your \verb|.mh_profile|, {\it bbc\/} will continue processing the next
+BBoard in the list.
+
+Here is an example of using {\it bbc\/} to read the system BBoard:
+

+\begin{footnotesize}

+
+The uci.edu will be down from
+       February  7,1986 17:10 till February  7,1986 20:30.
+The reason for the downtime is:
+Both, the Computing Facility and the Physical Sciences Dataswitches 
+will be unavailable from 5:10pm until 8:30pm on Friday, February 7th. 
+Therefore all the Computers attached to those switches and the 
+corresponding tandem link will be unavailable to users on 
+the specified time.              (RJ).
+
+Downtime Scheduler
+\end{verbatim}\leftline{\tt(msh) \itt quit}
+\leftline{\tt \%}
+\end{footnotesize}
+\newpage
+
+You can see a list of all the available BBoards by typing:
+
+\command{bbc -topics}
+
+You can also put a line in your ``\verb|.mh_profile|'' listing all
+the BBoards you want to read on a regular basis:
+
+\oneline{bboards: system movies mh-users events}
+
+Then you only need to type ``\verb|bbc|'' to read all your BBoards. 
+
+
+\section{Checking for Mail}
+
+Under \unix/, there are many different ways to check for new mail. The
+easiest way to do it is to set the {\it csh\/} variable named ``mail''
+to tell {\it csh\/} to check for new mail for you periodically. To
+do this, add the line
+
+       \oneline{set mail=(60 /usr/spool/mail/\$USER)}
+
+to the {\tt .login} file in your home directory.  This command says
+to check for mail if {\it csh\/} is about to prompt you with a
+{\tt \%} sign, and if it has been at least 60 seconds since it last
+checked for mail.  The advantage of this method of mail notification,
+besides simplicity, is that you will never be interrupted by a mail
+notification.  You will only be notified about new mail when you
+are between commands.
+
+If you want asynchronous mail notification, which will print to your
+terminal regardless  of what you are currently doing, you may make
+use of a ``receive mail hook'' called ``rcvtty''.  To do this, 
+create a file in your home directory called ``{\tt .maildelivery}''.
+In this file, put the line
+
+       \oneline{* - pipe R /usr/uci/lib/mh/rcvtty}
+
+Then, each time mail arrives, you will receive a one--line ``scan''
+listing of the mail if your terminal is world-writable.  For more
+information on mail delivery files, type:
+
+       \command{man 5 maildelivery}
+
+This will tell you about all the options available to you if you
+use maildelivery files.
+
+
+\section{Aliases}
+
+Using \MH/, you may specify your own private mail aliases.  This feature
+allows you to store lists of addresses or long internet addresses of people
+with whom you frequently correspond in one file, and then to address them
+using short mnemonic names.  Typically, you will call your alias file ``{\tt
+aliases}''; it must be stored in your \MH/ directory.  The format of this
+file is simple. The alias is given, followed by a colon, followed by one or
+more legal mail addresses separated by commas.  For example, you might for
+some reason have an alias for all the users named ``Rose'' in the ICS
+department:
+
+       \oneline{roses: prose, srose, mrose, drose}
+
+In addition to your ``{\tt aliases}'' file, you will need to modify your\break
+\verb|.mh_profile| in order to use aliases.  You should add the flag
+``{\tt -alias aliases}'' to the entries for the commands {\it ali, whom,
+send,} and {\it push,} creating entries for these programs if they aren't
+already in your \verb|.mh_profile|.
+Now, messages addressed to ``{\tt roses}'' will be distributed to all
+the people listed in the alias.
+
+The {\it ali\/} command is used to show you what an alias expands to.
+You just type
+
+       \comarg{ali}{alias}
+
+and {\it ali\/} will respond with the expansion of the {\it alias.}  {\it
+Ali\/} searches the system aliases file in addition to your private ones.
+
+\section{Blind Lists}
+
+There are two different types of so-called ``blind addressing'' of messages.
+The {\tt BCC:} field allows you to add recipients to your message just
+like those who are CC'd, but the normal recipients will not see that the
+BCC recipients were copied on the message, their replies will not go to the
+blind recipients, and the blind recipients cannot (easily) reply to the
+message.
+
+The second type of blind mailing is actually called a ``group address list'',
+although it is commonly referred to as a ``blind list''.
+The format of this type of address is
+
+       \oneline{{\it phrase\/}: {\it address\_list\/};}
+
+where the ``{\it phrase\/}'' is any English phrase of one or more words,
+and the {\it address\_list\/} consists of one or more addresses separated by
+commas.  The recipients of a message addressed in this fashion will
+see simply
+
+       \oneline{{\it phrase\/}: ;}
+
+so when they reply to the message, their reply will come only to the sender
+(or the {\tt Reply-To:} field, if one was specified), rather than going to
+all the recipients of the original list. For example, to use a group
+address list for the ``{\tt roses}'' alias you would type:
+
+       \oneline{To: People Named Rose: roses;}
+
+This type of group address is very
+useful for making up lists of related people, such as all the people working
+on a particular research project.

+ACKNOWLEDGEMENTS
+.LP
+The \fIMH\fP system described herein is
+based on the original RAND \fIMH\fP system.
+It has been extensively developed (perhaps too much so) by Marshall T. Rose
+and John L. Romine at the University of California, Irvine.
+Einar A. Stefferud, Jerry N. Sweet,
+and Terry P. Domae provided numerous suggestions
+to improve the UCI version of \fIMH\fP.
+.PP
+Of course,
+a large number of people have helped \fIMH\fP along.
+The list of \*(lq\fIMH\fP immortals\*(rq is too long to list here.
+For this release, numerous \fIMH\-Workers\fP sent in fixes and other
+changes.  A handful of courageous \fIMH\-Workers\fP volunteered
+to beta-test these changes; their help is particularly appreciated.

+CHANGES FOR MH 6.8
+.LP
+This is the current released version of \fIMH\fP
+as of December 14, 1992.  This release includes a number
+of bug fixes and internal changes to make the code more
+portable.
+Two new authentication methods are provided for the POP,
+and support for SVR4 shared libraries is complete.
+.PP
+The major user-visible change in this release is the incorporation
+of support for multi-media mail as specified by the
+Multi-purpose Internet Mail Extensions (\fBMIME\fP)
+RFC\ 1341.
+This allows you to include things like audio,
+graphics, and the like, in your mail messages.
+A new command, \fImhn\fP, 
+has been provided to support \fBMIME\fP and
+a detailed man page is provided in \fImhn\fP\|(1).
+.SH
+Documentation
+.LP
+The documentation has some general improvements, and
+the \fBREAD-ME\fP document has been re-organized
+to help \fIMH\fP administrators find the appropriate
+configuration options for their system.
+The \fBMakefile\fPs in the \fBpapers/\fP hierarchy have
+been changed to invoke \fITeX\fP as
+\*(lqtex\*(rq (instead of \*(lqtex82\*(rq).
+.LP
+The following new man pages are also available:
+.IP \fImhn\fP\|(1) \w'\fIpopauth\fP\|(8)'u+2n
+\fImhn\fP helps the user process multi-media mail.
+.IP \fImhparam\fP\|(1)
+\fImhparam\fP lets the user extract information from 
+the \fIMH\fP profile.
+.IP \fIpopauth\fP\|(8)
+the APOP database administration program (see below).
+.IP \fIpopi\fP\|(1)
+the POP initiator (see below).
+.IP \fIslocal\fP\|(1)
+fully documents \fIslocal\fP.  The \fImhook\fP(1) man page now
+documents only the \fIMH\fP receive-mail hooks.
+.SH
+Internal Changes
+.LP
+The \fIMH\fP source code is in the process of being
+cleaned up to make pedantic ANSI C compilers happy.
+Occurrences of \*(lqNULL\*(rq have been replaced by
+\*(lq0\*(rq where appropriate.
+Extra tokens after \*(lq#else\*(rq and \*(lq#endif\*(rq
+have been put inside comments (this is still in progress).
+The code should now compile cleanly on many more systems,
+specifically, more variants of SVR4.
+.PP
+The version of \fBtws/dtimep.c\fP which was included in 
+MH 6.7.2 was incompatible with the \fIlex\fP library
+on some systems, and has been removed.
+.PP
+A bug in the handling of blind lists inside alias
+files has been fixed.
+.KS
+.SH
+Post Office Protocol
+.LP
+There were three new options added to the POP.
+.IP APOP \w'APOP'u+2n
+This option indicates that the POP daemon will
+support the non-standard \fBAPOP\fP command which
+provides a challenge-based authentication system using
+the \fBMD5\fP message digest algorithm.
+.IP
+This option also causes the
+\fIpopauth\fP program to be installed, which
+allows the administrator to manipulate the \fBAPOP\fP
+authorization database.
+.KE
+.IP KPOP
+Support for KERBEROS with POP.
+This code builds
+\fIpopd\fP, \fIinc\fP and \fImsgchk\fP to support only the 
+\*(lqkpop\*(rq protocol.
+This code is still expiremental, but is available for 
+those sites wishing to test it.
+.IP MPOP
+This option indicates that the POP daemon will
+support the non-standard
+\fBXTND SCAN\fP command which provides performance
+enhancements when using the POP over low-speed connections.
+.IP
+This option also causes an interactive POP
+client program, \fIpopi\fP, to be compiled and installed.
+A man page for the \fIpopi\fP program is also provided.
+This option requires the configuration to
+have \*(lqbboards: pop\*(rq.
+.LP
+The APOP and MPOP non-standard POP
+facilities are documented in
+\fIThe Internet Message\fR (ISBN 0\-13\-092941\-7),
+a book by Marshall T. Rose.
+For more details, see \fBsupport/pop/pop-more.txt\fR
+and the \fIAdministrator's Guide\fP.
+The APOP option peacefully co-exists with the standard POP,
+KPOP completely replaces the standard POP, and
+MPOP requires \*(lqbboards: pop\*(rq.
+.SH
+File Locking
+.LP
+The file locking code has been cleaned up to support
+three kinds of kernel-level file locking.  As appropriate
+for your system, include the
+LOCKF, FCNTL or FLOCK option.  For more
+details, see \fImh-tailor\fP\|(5).
+.SH
+.KS
+Configuration Directives
+.LP
+A number of new configuration directives have been added
+or changed.  The full details are given in the \fBREAD-ME\fP.
+.IP cp: \w'MAILGROUP'u+2n
+The command used to install new files if not \*(lqcp\*(rq.
+.IP ln:
+The command used to link files together in the source tree
+if not \*(lqln\*(rq.
+.IP mts:
+Full support for ZMAILER has been added.
+.IP popdir:
+The directory where \fIpopd\fP will be installed if not \fB/usr/etc\fP.
+.IP regtest:
+Set to \*(lqon\*(rq to prevent the hostname and compile
+date from being included in \fIMH\fP binaries.
+.IP sharedlib:
+You may now specify \*(lqsun4\*(rq or \*(lqsys5\*(rq 
+(for SVR4) shared libraries.
+.IP signal:
+Specifies the base type of the function returned by \fIsignal\fP\|().
+This was previously defined with \*(lqoptions TYPESIG\*(rq.
+.KE
+.LP
+Several `-D' options to \fIcc\fP have been added or changed:
+.IP APOP \w'MAILGROUP'u+2n
+Authenticated POP (see above).
+.IP AUX 
+Support for A/UX systems.
+.IP DBMPWD
+The DBM option has been renamed DBMPWD.
+.IP HESIOD
+Support for the HESIOD name server.
+.IP KPOP
+KERBEROS POP (see above).
+.IP LOCALE
+Support for local characters sets; uses the \fIsetlocal\fP\|() function.
+.IP MAILGROUP
+Makes \fIinc\fP set-group-id.
+You may need this option if your \fB/usr/spool/mail\fP
+is not world-writeable.
+.IP MIME
+Multi-media mail.
+.IP MPOP
+Mobile POP (see above).
+.IP MSGID
+Enables \fIslocal\fP to detect and surpress duplicate messages.
+.IP OSF1
+Support for DEC OSF1 systems.  May be incomplete.
+.IP RENAME
+Include this option if your system has a \fIrename\fP\|()
+system call.
+.IP SVR4
+Support for System 5 Release 4 or newer systems.
+.IP TYPESIG
+This option has been dropped.  See `signal' above.
+.IP UNISTD
+Include this option if your system has the include
+file \fB<unistd.h>\fP.
+.IP VSPRINTF
+Include this option if your system has the \fIvsprintf\fP\|()
+library routine; otherwise, \fI\(rudoprnt\fP\|() will be used.
+.IP YEARMOD
+Forces the \fImh-format\fP `year' function to
+return 2-digit values.
+Use this option during a brief transition period if 
+you have local \fImh-format\fP files which need to
+be converted to support 4-digit years.
+.SH 
+FUNCTIONAL CHANGES
+.LP
+In addition to the configuration changes mentioned above,
+a number of functional changes have been made to the system.
+Many programs have new features added and a few new 
+programs have are provided.  
+Each command's manual page gives
+complete information about the its operation.
+Here is a short summary of the changes.
+.SH
+MH Sequences
+.LP
+A larger number of user-defined sequences are available.
+Previously, this number had been 10.
+On 32-bit systems, 26 user-defined sequences are available.
+.SH
+Profile Components
+.LP
+\fIMH\fP programs will now complain if the 
+\fB\&.mh\(ruprofile\fR does not end in a newline.
+Also, one enhancement and one new profile component are provided:
+.IP Aliasfile: \w'AliasfileX'u+2n
+Multiple filenames may now be given.
+.IP Inbox:
+New; the default folder (for \fIinc\fP, etc.) if not \*(lqinbox\*(rq.
+.KS
+.SH
+Format Strings
+.LP
+A few minor bugs were fixed in format string handling,
+and a few new features were added.  See \fImh-format\fP\|(5)
+for complete details.
+.IP Addresses \w'Xxyearxdatexx'u+2n
+An attempt is made to decipher X\&.400 RFC\ 987-style addresses.
+.IP Comments
+Comments may be added to \fImh-format\fP files; a comment
+begins with the 2-character sequence \*(lq%;\*(rq,
+and ends with an un-escaped newline.
+.IP "%(modulo n)"
+The `modulo' function escape has been added.
+.IP %(year{date})
+The date parser has been enhanced to understand more
+illegal date formats; `year' now returns a 4-digit number.
+.KE
+.SH
+User Interface Programs
+.LP
+A number of \fIMH\fP commands have minor changes:
+.IP ali \w'packmbox'u+2n
+The output with `\-user\0\-list' was
+changed to match the output with `\-nouser\0\-list'.
+.IP burst
+Will no longer drop the last message of a digest.
+.IP inc
+Accepts the `\-apop' switch for authenticated POP (see above);
+will attempt to detect write
+errors (e.g., no space left on device) when incorporating mail;
+no longer replaces newline characters with NULLs.
+.IP folder
+The `\-noprint' option was broken and has been dropped.
+.IP forw
+Supports `\-mime' to use MIME-style multi-part messages.
+.IP mhl
+Will no longer put an extra space at the end of the
+`%{text}' in a formatfield.
+.IP mhn
+New; manipulates multi-media (MIME) messages; a detailed
+man page is provided.
+.IP mhparam
+New; reads the \fIMH\fP profile (and context) 
+and writes the values of the specified components on the
+standard output; useful in programmatic constructs.
+.IP msgchk
+Supports `\-apop' (see above).
+.IP packmbox
+New; packs an \fIMH\fP folder into a UUCP-style mailbox.
+.IP popi
+New; a client-side POP initiator; available only if you
+built \fIMH\fP with the MPOP option (see above).
+.IP refile
+A bug where the `rmmproc' did not remove all specified
+message files has been fixed.
+.IP scan
+The `\-file' option is fully supported and will no longer
+complain about empty folders.
+.IP send
+Supports `\-mime' and `\-split' to split large messages
+into multiple partial messages using MIME.
+.SH
+Support Programs
+.IP fmtdump \w'packmbox'u+2n
+Can now read a format file, or a format string given
+on the command line.
+.IP popauth
+New; manages the APOP authorization database (see above).
+.IP sendmail
+The \fIsendmail\fP replacement will be installed
+only if your `mts' setting uses the `/smtp' option.
+.IP slocal
+A new man page for \fIslocal\fP is available;
+the new `mbox' action is available to write a file
+in \fIpackf\fP format;
+a bug where extra `>' characters were written to MMDF-style
+maildrops has been fixed;

+CHANGES FOR MH 6.7.2
+.LP
+The MH.6.7.2 patch release is a maintenance
+release.
+This is the
+current released version of \fIMH\fP as of February 1, 1992.
+.PP
+This release now supports the NCR Tower running SYS5R4.
+The WP changes installed in MH.6.7.0 have been removed.
+.SH 
+Shared Libraries
+.LP
+Support for SYS 5 shared libraries is in progress.
+.PP
+Support for Sun OS 4.0 shared libraries had been improved.
+The \fIMH\fP library has been modified to move initialized
+data into a data definition file.  The shared library will
+now consist of a \fBlibmh.so\fP and \fBlibmh.sa\fP file.
+The shared library version number will no longer track the
+\fIMH\fP patch release number, and its numbering begins with
+version `1.1' with this release.
+.SH
+Replacement SendMail
+.LP
+Since many standard system programs expect to post mail by 
+invoking \fB/usr/lib/sendmail\fP,
+a minimal replacement \fISendMail\fP is provided in 
+this release.  This replacement is meant to be installed
+on (e.g., diskless) client workstations which post mail
+using SMTP, and do not run a message transport system.
+It will call \fIpost\fP to post mail; be sure you have
+configured \fIMH\fP with the `/smtp' mts option.
+This sendmail replacement is installed in your 
+\fIMH\fP etc directory, and you should link 
+\fB/usr/lib/sendmail\fP
+to it.
+.KS
+.SH
+Format Strings
+.LP
+A manual page for the \fIfmtdump\fP format string disassembler
+is supplied, and some new format functions were added:
+.IP folder \w'%getenv'u+2n
+In \fIscan\fP, this component escape
+contains the name of the current folder.
+It is not defined for other \fIMH\fP commands.
+.IP getenv
+This function escape returns the value of an environment variable.
+.KE
+.PP
+There will be some additional changes in these routines in the
+next patch release.
+.KS
+.SH
+Other Bug Fixes and Enhancements
+.LP
+In addition to some other minor enhancements,
+some bugs were fixed which in general were not user\-visible:
+.IP "Blind lists" \w'datexparsing'u+2n
+Users may now specify RFC822 address groups in their
+alias files.  These groups are implemented by \fIMH\fP 
+as blind lists.
+.IP "date parsing"
+A number of sites have brain-damaged versions of \fBlex\fP.
+\fIMH\fP will now come with the date parser already run
+through lex.
+.IP mark
+A bug dealing with \fImark\fP and the sequence named `cur'
+is fixed.  This was previously a problem for mh-e users.
+.IP MH.doc
+The \fIMH\fP nroff version of the manual no longer contains
+teletype escape sequences.
+.IP scan
+Can now handle headers as long as 512 bytes.
+.IP Signals
+\fIMH\fP programs will no longer catch the \fBHUP\fP
+and \fBTERM\fP signals while waiting for a sub-process.
+This was causing hung processes when your terminal line was
+was dropped unexpectedly.
+.IP Signature
+If your signature is not defined, \fIMH\fP will 
+use the value of the gecos field of your \fB/etc/passwd\fP
+entry as your signature.
+.IP "version.sh"
+A bug in the \fBawk\fP script in \fBconfig/version.sh\fP 
+was fixed.

+CHANGES FOR MH 6.7.1a
+.LP
+The MH.6.7.1a patch was made available 
+on January 25, 1991 for limited distribution only.
+(This release had some known bugs, and so was
+not widely distributed.)
+This release incorporates several new features
+of particular note to users of sequences and format strings,
+as well as some general documentation improvements.
+There are a few minor enhancements and internal bug fixes also.
+Complete documentation of these changes is given in
+the individual manual pages, and the \fBREAD-ME\fP file.
+.SH
+Message Sequences
+.LP
+A new manual page, \fImh\-sequence\0\fP(5), has been added.
+This manual page attempts to completely document the
+syntax and semantics of \fIMH\fP message sequence specifications.
+.PP
+A powerful new feature is the ability to specify message
+ranges with user-defined sequences.  The  specification
+\*(lqname:n\*(rq may be used, and it designates up to the
+first `n' messages (or  last  `n' messages  for  `-n')
+which  are  elements  of the user-defined sequence `name'.
+.PP
+The message
+specifications \*(lqname:next\*(rq and \*(lqname:prev\*(rq
+may also be used, and they
+designate the
+next or previous message (relative to the current message)
+which is an element of the user-defined sequence `name'.
+The specifications
+\*(lqname:first\*(rq and \*(lqname:last\*(rq are equivalent
+to \*(lqname:1\*(rq and \*(lqname:\-1\*(rq, respectively.
+The specification \*(lqname:cur\*(rq is not allowed
+(use just \*(lqcur\*(rq instead).
+.PP
+These specifications allow the user to step through
+a sequence with a command like \*(lqshow name:next\*(rq.
+.SH
+Format Strings
+.LP
+\fIMH\fP format strings now support an if-then-elseif-else
+clause (the `elseif' is new).  This will make
+format strings with multi-case conditions somewhat less complex.
+.PP
+A new format function `addr' had been added.  This function
+takes an address header name as its argument, and returns
+a rendering of the address contained in that header
+as \*(address@hidden(rq or \*(lqhost!user\*(rq.
+.PP
+Format widths now may be specified as a negative number.
+This causes the output to be right-justified
+within the format width.
+.KS
+.SH
+Other Changes
+.LP
+Along with a few minor enhancements,
+some bugs were fixed which in general were not user-visible:
+.IP "fmtdump" \w'whatnow'u+2n
+This new program 
+produces an pseudo-language
+representation of an \fIMH\fP format file, vaguely
+reminiscent of assembly language.  While this output format
+is not explicitly documented,
+it can still be useful when debugging \fIMH\fP format files.
+.IP "refile"
+Now takes a `\-\[no\]rmmproc' switch.  This makes it
+easier to avoid loops when your \*(lqrmmproc\*(rq calls \fIrefile\fP.
+.IP "slocal"
+A problem with the UUCP-style mailboxes,
+the `RPATHS' configuration option,
+and the \*(lqReturn-Path:\*(rq header was fixed.
+.IP "sortm"
+Will ensure that no messages are lost if it is interrupted.
+.IP "whatnow"
+Will now tell you where it is leaving the draft, when
+interrupted in the initial edit.  Previously the draft 
+was simply unlinked.
+.KE
+.KS
+.SH
+Compilation Options
+.IP "LOCKF" \w'whatnow'u+2n
+This option causes \fIMH\fP to use the \fBlockf()\fP
+system call for locking (if available),
+instead of \fBflock()\fP.

+.SH 
+CHANGES FOR MH 6.7.1
+.LP
+The MH.6.7.1 patch release is a maintenance
+release, and as such, provides few changes from 
+the previous release.  This is the
+current released version of \fIMH\fP as of December 14, 1990.
+.SH
+User-Visible Changes
+.LP
+The major change in this release is to the
+POP daemon (popd).  In \fIMH\fP 6.7,
+it was changed to be able to read both UUCP and
+MMDF-style mailboxes.  This did not work as reported.  The
+code has now been changed to parse MMDF-style mailboxes if
+you are configuring MH to run with MMDF as your message
+transport system.  Otherwise, UUCP-style mailboxes are
+expected.
+.PP
+Since there are number of client programs available for
+only the POP2 protocol instead of POP3, popd has been
+updated to support both protocols.  This is a major
+win.  If you are compiling
+with POP turned on, add the `POP2' option to
+your \fIMH\fP config file, and the POP daemon
+will respond to POP2 or POP3 commands.  If you're using
+POP, there's no reason not to include this option; it does
+not affect the existing support for POP3.
+.KS
+.SH
+Internal Changes
+.LP
+Some bugs were fixed which in general were not user-visible:
+.IP "context" \w'replnnetcn'u+2n
+Errors when writing out sequences are detected correctly.
+.IP "inc"
+No longer inserts extra blank lines into messages.
+.IP "mh-format"
+A nil pointer bug in the address parser was fixed.
+.IP "repl, etc."
+The malloc/free problem has been fixed.
+.IP "rmf"
+A spelling error in the `\-nointeractive' switch has been corrected.
+.IP "rcvtty"
+Will not print the message size if not available (i.e., zero).
+.IP "send/post"
+Illegal signatures (those containing unquoted "."s) will be quoted.

+GENERAL CHANGES FOR MH 6.7.0
+.LP
+The author is pleased to announce that there are very few
+user\-visible
+changes to \fIMH\fP 6.7 from the previous \fIMH\fP 6.6 distribution.
+The majority of development was in the form of bug fixes and
+slight enhancements.
+In addition, this release is slightly faster than the
+previous release.
+With a few minor exceptions,
+it is backward\-compatible with the previous release.
+\fIMH\fP 6.7.0 is the current released version of \fIMH\fP
+as of April 12, 1990.
+.PP
+The changes were made mainly to generalize the source code to
+be compatible with a larger range of systems and compilers.
+There were many small changes to add declarations for ANSI C compliance.
+The System 5 support has been brought up to SYS5 R3, and there is
+support for Sun OS 4.0.
+.SH
+User\-Visible Changes
+.LP
+Here a quick summary of the
+changes that were made which are not backward\-compatible with the
+previous release of \fIMH\fP:
+.IP repl \w'sortm'u+2n
+The `\-format' and `\-noformat' switches
+have not been functional since \fIMH\fP 5, and have been removed.
+Any users who have these switches in their \fB\&.mh\(ruprofile\fP,
+will have to remove them.
+.IP sortm
+Previously, in most cases \fIsortm\fP would fill\-in any
+gaps in the numbering of a folder, 
+by renumbering the messages starting with `1'.
+This will no longer occur; for this behavior,
+use \*(lqfolder \-pack\*(rq.
+.PP
+.SH
+Using Aliases
+.LP
+A new profile entry `Aliasfile:' has been added.  The
+\fIali\fP\^, \fIsend\fP\^, and \fIwhom\fP programs will look for
+this profile entry and treat it as they would an argument to
+`\-alias'.
+This should make it easier for novice \fIMH\fP users to begin
+using aliases.
+.PP
+.SH
+Reading Network News & BBoards
+.LP
+The UCI BBoards facility can read local BBoards, and if compiled
+with the `bboards: pop' and `pop: on' options, can also read remote
+BBoards using the Post Office Protocol (POP ver. 3).
+With this release,
+\fIMH\fP can instead be compiled to read the Network News
+(i.e., USENET) using the Network News Transfer Protocol (NNTP).
+.PP
+This capability is enabled by compiling \fIMH\fP with
+the `bboards: nntp' and `pop: on' options.
+Unfortunately, reading remote BBoards via the POP and reading the Network
+News via the NNTP are mutually exclusive options.
+.PP
+To support the NNTP,
+a new module, \fBuip/pshsbr.c\fP, is compiled and loaded into
+\fIbbc\fP and \fImsh\fP instead of \fBuip/popsbr.c\fP.
+The default BBoard is changed from \*(lqsystem\*(rq to \*(lqgeneral\*(rq
+for the NNTP.
+.PP
+When reading BBoards,
+\fIbbc\fP will first look for local BBoards, and then contact the
+NNTP server to read the Network News.  The location of the
+NNTP server should be specified with the `nntphost:'
+entry in the \fBmtstailor\fP file
+(see the \fIMH\fP Administrator's Guide for details),
+or may be specified on
+the command line with the `\-host' switch.
+.PP
+.SH
+Format Strings
+.LP
+The manual page \fImh\-format\fP\0(5) has
+been rewritten to give a better explanation of how to write format strings,
+and how they are interpreted by \fIMH\fP.
+A line\-by\-line
+description of the 
+default \fIrepl\fP form file (\fBreplcomps\fP)
+is now included in that manual page.
+.PP
+.KS
+Some new format functions were added, and others were augmented:
+.IP trim \w'date2local'u+2n
+Strips any leading and trailing white\-space from the current string value.
+.IP date2local
+Will coerce the date to the local timezone.
+.IP date2gmt
+Will coerce the date to GMT.
+.IP divide
+Divides the current numeric value by its argument.
+This could be useful for
+building \fIscan\fP format strings which print large
+message sizes in \*(lqKb\*(rq or \*(lqMb\*(rq.
+.IP friendly
+If the address field cannot be parsed,
+this function will return the text of the address header,
+instead of a null string.
+.IP szone
+A flag indicating whether the timezone was explicit
+in the date string.
+.KE
+.SH
+PROGRAM CHANGES
+.LP
+In addition to the general changes mentioned above,
+many programs have specific new features added,
+either by new switches or by expanded functionality.
+Each command's manual page gives complete information about
+its new options.  Here is a short summary.
+.SH
+User Interface Programs
+.IP anno \w'prompter'u+2n
+Accepts a `\-nodate' switch which inhibits the date annotation,
+leaving only the body annotation.
+.IP folder
+When invoked with the `\-pack' switch
+and the new `\-verbose' switch, \fIfolder\fP will
+give information about the actions taken to renumber the folder.
+.IP
+On most systems, \fIfolder\fP can now create any non\-existing
+parent folders of a new sub\-folder.
+.IP forw
+When making digests, \fIforw\fP\^
+will put the issue and volume numbers
+in addition to the digest list name, in the digest trailer.
+.IP inc
+Detects NFS write failures, and will
+not zero your maildrop in that event.
+.IP msh
+Supports a variant of the new \fIsortm\fP\^.
+.IP prompter
+Considers a period on a line by itself to signify end\-of\-file
+when the `\-doteof' switch is specified.
+.IP repl
+The `\-[no]format' switches
+have not been used since \fIMH\fP 5 and have been deleted. \fIrepl\fP
+will now find filter files in the \fIMH\fP library area.
+.IP scan
+With the `\-file msgbox' switch, \fIscan\fP\^
+can list a \fIpackf\fP\|'d\-format file directly
+(without using \fImsh\fP\^).
+.IP
+Lists messages in reverse order with the `\-reverse' switch.
+This should be considered a bug.
+.IP sortm
+Now has the options:
+`\-textfield field', `\-notextfield',
+`\-limit days', and `\-nolimit'.
+.IP
+With these options, \fIsortm\fP can be instructed to sort a
+folder based on the contents of an arbitrary header such
+as \*(lqsubject\*(rq.
+.IP
+\fIsortm\fP minimizes renaming messages, and
+will no longer arbitrarily pack folders; for this behavior,
+use \*(lqfolder \-pack\*(rq.
+.IP whatnow
+Deletes the draft by renaming it with leading comma, instead
+of unlinking it.
+.SH
+\fIMH\fP Support Programs
+.LP
+.KS
+The following support programs also have changes or enhancements:
+.IP mhl \w'rcvtty'u+2n
+Will now accept a format string on any component, not just on
+addresses and dates.
+.KE
+.IP popd
+Will use \fIshadow\fP passwords if compiled with the
+\fBSHADOW\fP option.  It can now also
+read UUCP\-style maildrops directly.
+.IP rcvtty
+If given no arguments, \fIrcvtty\fP will produce a \fBscan\fP
+listing as specified by a format string or file; a default
+format string is used if one is not specified.
+.IP
+Before the listing is written to the users terminal, the
+terminal's bell is rung and a newline is output.
+The `\-nobell' and the `\-nonewline' options
+inhibit these functions.
+.IP
+\fIrcvtty\fP will obey terminal write
+notification set by \fImesg\fP.
+With the `\-biff' switch, \fIrcvtty\fP will
+also obey the mail notification status set by
+\fIbiff\fP.  
+.IP
+On \fBBSD43\fP systems, as with \fIwrite\fP,
+\fIrcvtty\fP will be installed set\-group\-id to the group \*(lqtty\*(rq.
+.IP slocal
+Understands UUCP\-style \*(lqFrom \*(rq lines and will write
+output files using this format if appropriate.
+Before invoking a delivery program, \fIslocal\fP will strip
+such lines unless compiled with the \fBRPATHS\fP option,
+in which case it will will convert such lines into
+\*(lqReturn\-Path:\*(rq headers.
+.IP
+\fIslocal\fP has a new result code \*(lqN\*(rq,
+for use in \fB.maildelivery\fP files.
+With this result code,
+\fIslocal\fP will
+perform the action only if the message has not been delivered
+and the previous action succeeded.  This allows for performing
+an action only if multiple conditions are true.
+.SH
+DOCUMENTATION
+.LP
+Several of the older \fIMH\fP papers have been difficult to format
+because they depended on an older version of
+PhDTeX which was
+not supplied.  These papers have been updated, and some TeX
+library files are supplied in \fBpapers/doclib/\fP, so that
+these papers may be generated on any system with TeX.
+.PP
+Many of the manual pages have been revised to include documentation
+of new command options, and some have been expanded to give more detail.
+All are now slightly reformatted at installation time
+to make them more compatible with programs like \fImakewhatis\fP\^.
+.PP
+.SH
+\fIMH\fP ADMINISTRATION
+.LP
+This section describes changes in configuring, compiling and
+installing \fIMH\fP 6.7 and should not
+be of interest to casual \fIMH\fP users.
+The \fBREAD\-ME\fP file has been 
+considerably revised and expanded to give more detail 
+about the configuration and compilation options which
+have been included in this release.  Some compilation options
+have been removed, and many new options have been added.
+.PP
+All \fIMH\fP \fBMakefile\fPs have been updated to work around some
+incompatibilities introduced in newer versions of \fImake\fP\^.
+\fIMH\fP programs will no longer be installed with the sticky\-bit
+turned on.
+.PP
+Reading this section not a substitute for carefully
+reading the \fBREAD\-ME\fP file before attempting to compile \fIMH\fP
+.PP
+.KS
+.SH
+Bug Fixes
+.LP
+Some bugs were fixed which in general were not user\-visible:
+.IP "address parser" \w'dynamicnmemory'u+2n
+Fixed to allow use of the \*(lqAT\*(rq domain, and some
+minor bugs were fixed pertaining to address groups.
+.IP "date parser"
+Improved to accept more forms of illegal dates.  Military
+timezones were removed.
+.IP "dynamic memory"
+Many problems with corruption of the dynamic memory pool
+have been fixed.
+.IP locking
+Will open files for write, if necessary to enable locking.
+.IP "nil pointers"
+All reported nil pointer problems have been fixed.
+.IP replcomps
+The \*(lqIn\-Reply\-To:\*(rq header had quotes added
+around the date field to comply with RFC822.
+.KE
+.SH
+White Pages
+.LP
+If \fIMH\fP is compiled with the \fBWP\fP option,
+\fIsend\fP recognizes an address between \*(lq<<\*(rq and \*(lq>>\*(rq 
characters
+such as:
+.DS
+To: << rose \-org psi >>
+.DE
+to be a name meaningful to a whitepages service.  In order to expand the
+name, \fIsend\fP must be invoked interactively
+(i.e., not from \fIpush\fP\^).  For each
+name, \fIsend\fP will invoke a command called \fIfred\fP\^
+in a special mode asking to expand the name.
+.PP
+To get a copy of the white pages service, contact address@hidden
+.SH
+Configuration Options
+.LP
+Some configuration options have been added or changed:
+.IP cc \w'bbdelivery'u+2n
+To specify an alternate C compiler.
+.IP ccoptions
+Defaults to `\-O'.
+.IP bboards
+May now be defined as \*(lqon\*(rq,
+\*(lqoff\*(rq, \*(lqpop\*(rq, or \*(lqnntp\*(rq.
+.IP bbdelivery
+Determines whether the bboard delivery agent
+and library files should be installed.
+.IP lex
+To specify an alternate version of \fIlex\fP\^.
+.IP mailgroup
+If defined, \fIinc\fP will be made set\-group\-id to this group.
+.IP sharedlib
+For \fBSUN40\fP systems; if \*(lqon\*(rq, makes \fBlibmh.a\fP
+into a shared library.
+.IP slibdir
+The directory where the above shared library should be installed.
+.IP sprintf
+Set this to \*(lqint\*(rq if that's what your \fIsprintf\fP\0(3) library
+routine returns.
+.SH
+Compilation Options
+.LP
+For different configurations,
+several `\-D' options to \fIcc\fP have been added or changed:
+.IP BERK \w'SENDMAILBUG'u+1n
+This disables the address and date parsing routines.  If you
+want to do much with \fImh\-format\fP\0(5), don't enable this.
+.IP BSD43
+Will make \fIrcvtty\fP set\-group\-id to the group \*(lqtty\*(rq.
+.IP DBM
+For sites with a dbm\-style password file (such as with Yellow
+Pages), \fIMH\fP will not read the entire passwd file into a cache.
+At one site that runs YP on a large passwd file, using this
+showed a 6:1 performance improvement.
+.IP NETWORK
+This option has been deleted.  See \fBSOCKETS\fP.
+.IP NOIOCTLH
+Tells \fIMH\fP not to include the file \fBsys/ioctl.h\fP.  Use this
+if this file is not present on your system.
+.IP NTOHLSWAP
+On systems with TCP/IP networking,
+\fImsh\fP will try to use the \fBntohl()\fP macro from the
+file \fBnetinet/in.h\fP to byte\-swap the binary map files
+it writes.
+.IP SENDMAILBUG
+Some versions of \fIsendmail\fP return a \fB451\fP (failure) reply code
+when they don't mean to indicate failure.  This option considers
+that code to be equivalent to \fB250\fP (OK).
+.IP SHADOW
+Causes \fIpopd\fP to read the file \fB/etc/shadow\fP for
+encrypted passwords instead of \fB/etc/passwd\fP.  Use this if you
+have a shadow password file (such as on newer versions of SYSTEM 5).
+.IP SOCKETS
+Enable this if you are on a non\-BSD system with a
+socket interface for TCP/IP networking compatible with 4.2BSD
+.SM
+UNIX.
+.NL
+.IP SUN40
+Use on Suns running Sun OS 4.0 and later.
+.IP SYS5
+This option has been updated to refer to SYS5 R3 and later systems.
+.IP SYS5DIR
+Use this if your system uses \*(lqstruct dirent\*(rq instead of
+\*(lqstruct direct\*(rq.  This should be true for systems based
+on SYS5 R3 and later.
+.IP TYPESIG
+Defines the base type for the \fIsignal\fP system call.  This
+defaults to \*(lqint\*(rq, but should be defined as \*(lqvoid\*(rq
+if appropriate for your system.
+.IP WP
+Enables support for the White Pages service.
+.SH
+Installation
+.LP
+\fIMH\fP will now
+explicitly set the protection mode on every file it installs.
+.PP
+Previously any existing file installed by \fIMH\fP
+would be backed up into
+the source tree, and then overwritten.
+Now, a few system\-dependent files will not be overwritten, and your
+changes will have to be merged in by hand.
+See the \fBREAD\-ME\fP file for more details.

+% Citations:
+% We keep a running list, address@hidden, which is
+% all the things which were \cite'd throughout the paper, with
+% only one entry for each different key.
+%
+% There are three versions of each of the citation
+% commands:
+% 1. The \def'd version is the normal one used throughout the paper.
+% 2. Within a figure, table, etc,'s caption, because of the use of
+%    \def and \edef, a special version which just produces the
+%    citation without the \gaddtolist command is used.  These
+%    definitions are predefined, and are \let to be \cite etc with
+%    address@hidden, for speed.
+%
+% When the user requests a citation with key, we first look it up
+% in a translation table called address@hidden, organized as a list of
+% <key, printed-key> pairs, to see if it really should be
+% printed differently.  The user can specify this translation table using
+% the \printkey command.  If a key is not in the table, it is printed
+% as-is.
+
+% We keep the dimension address@hidden as the largest printed key so far.
+% This value can then be used to print the keys in the bibliography
+% optimally, rather than just trying to guess.  Each time we print a
+% (in address@hidden), we see if it's longer than address@hidden, and if so 
then
+% we set address@hidden = its width.

+% The basic strategy is as follows.  We read the bib. file, which is
+% assumed to be in sorted order of keys/author names.  Each
+% entry is of the form \ref{key}.  We see if that key is in the table
+% address@hidden, which is a table of all the keys we've \cite'd.  If the key
+% isn't in the list, we print it in parens and go on to the next entry.
+% Otherwise, we print the key in square brackets, and format the
+% bibliography entry according to the format (JACM or IEEE).  We print a
+% warning if the key is in the address@hidden list.  We add the key to
+% the address@hidden list.  The key is removed from the address@hidden list if 
it
+% was there.  At the end of the references (\endreferences), we check
+% if there are any keys left in address@hidden  If so, the bib. file was
+% deficient, and we print a warning message (it should probably be a
+% fatal error message).

<address@hidden>
+
+       uip/prompter.c: with BSD42, do a clearerr() on stdin when we get

+       dynamic, it contains pfolder and private sequences.  The latter is
+       static, it contains switches, etc.  The ctx file defaults to

+               The select sub-folder is dead!
+               Long live user-defined sequences!
+           Pick got rid of 11 (!!) switches this way, and we've taken our

+       uip/{bbr$scan,inc,scan,scansbr}.c: Only do the ftell() business

<address@hidden>
+
+       Install the new Previous-Sequence mechanism.  Introduce the SEQMOD

+\noindent
+This document describes user-visible changes to the
+UCI version of the Rand \MH/ system that were made
+from \mh3 to \mh4.
+In particular,
+four facilities are discussed:
+multiple composition of drafts,
+user-defined sequences,
+the folder-stack,
+and,
+relative folder addressing.
+This document does not describe bug-fixes, per se,
+or internal changes,
+unless these activities resulted in a visible change for the \MH/ user.
+\par
+This document is meant to supplement,
+not supersede, the standard \MH/ user manual\cite{MH}.

+\section{Acknowledgements}
+The \MH/ system described herein is based on the original Rand \MH/ system.
+It has been extensively developed (perhaps too much so) by Marshall Rose and
+John Romine at the University of California, Irvine.
+Einar Stefferud, Jerry Sweet, and Terry Domae provided numerous suggestions
+to improve the UCI version of \MH/.
+\section{Disclaimer}
+The Regents of the University of California wish to make it known that:
+\bigquote
+Although each program has been tested by its contributor,
+no warranty, express or implied,
+is made by the contributor or the University of California,
+as to the accuracy and functioning of the program
+and related program material,
+nor shall the fact of distribution constitute any such warranty,
+and no responsibility is assumed by the contributor
+or the University of California in connection herewith.

+\section{Conventions}
+In this document,
+certain \TeX -formatting conventions are adhered to:
+{\advance\leftskip by\parindent
+\item{1.} The names of \unix/ commands, such as \pgm{comp},
+are presented in {\it text italics}.
+\item{2.} Arguments to programs, such as \arg{msgs},
+are presented in {\sl slanted roman} and delimited by single-quotes.
+\item{3.} \unix/ pathnames and envariables,
+such as \file{/usr/uci/} and \file{\$SIGNATURE},
+are also presented in {\sl slanted roman}.
+\item{4.} Text presenting an example, such as \eg{frated},
+is presented in {\tt typewriter style}.
+\item{5.} Entries in the user's \MH/ \profile/ and \context/ files,
+such as \entry{Current-Folder},
+are presented in {\sc Caps-Small-Caps} and delimited by a box.
+\smallskip}
+\bop\section{General Changes}
+This section discusses system-wide changes to \MH/ that are general in nature.
+\subsection{Message Numbering}
+In previous versions of \MH/, a folder could have up to \eg{999} messages;
+in \mh4, this limit has been raised to \eg{1999}.
+\subsection{Version Information}
+When any \MH/ command is invoked with the \switch{help} switch,
+in addition to listing the syntax of the command,
+the program will list information pertaining to its version.
+This information includes the version of \MH/,
+the host it was generated on,
+and the date the program was loaded.
+For example,
+\example MH \#4.25[UCI] (uci-750b) of Thu Jul 19 21:07:01 PDT 1984\endexample
+The \eg{\#4.25[UCI]} indicates that the program is from the UCI \mh4
+version of \MH/.
+The program was generated on \eg{uci-750b},
+on \eg{Thu Jul 19 21:07:01 PDT 1984}.
+\par
+This information is sometimes useful in the unusual circumstance when a bug
+is found in \MH/.
+By providing the version information,
+along with the circumstances concerning the problem with \MH/,
+the local \MH/ maintainer is better able to track-down the problem.
+\subsection{The User Context}
+The \MH/ profile for the user now consists of two parts:
+a static part, the \profile/, which is found in the user's \file{\$HOME/}
+directory,
+and, a dynamic part, the \context/, which is usually found in the user's \MH/
+directory.
+The former file contains information which \MH/ commands read,
+but {\it never\/} write
+(e.g., command switches).
+The latter contains information that \MH/ commands read and write,
+(e.g., \entry{Current-Folder}).
+\par
+This change has three advantages over the way things were done in \mh3.
+\underbar{First},
+a lot less information gets written out when an \MH/ command exits,
+if the context changes.
+This is due to the fact that the user's \context/ file is often much,
+much smaller than a user's \profile/ file.
+\underbar{Second},
+one can keep different context files around
+(the entry \entry{context} is changed in the user's \profile/ file).%
+\nfootnote{Note that this entry must be given {\it entirely} in lowercase in
+the \profile/ file.}
+Hence, the \MH/ user can maintain different sets of private sequences
+(explained later),
+by manipulating different \context/ files.
+\underbar{Third},
+if more than one person uses a \unix/ login
+(say a maintenance account),
+then each can define their own \file{\$MH} envariable to point to their
+\profile/ file.
+As a result,
+each user has the \MH/ environment which that user is accustomed to.
+Further,
+depending on the needs of the users who share the \unix/ login,
+the same or different contexts may be automatically maintained for that login.
+\par
+See \man{mh-profile}(5) for more details on the user context file.
+\section{Message Selection}
+A new facility has been added to give the \MH/ user greater power in
+selecting and referencing messages:
+first, a change to the \pgm{pick} program is described;
+second, the notion of user-defined sequences is detailed.
+\subsection{Selecting Messages}
+The \pgm{pick} command now does only one thing:
+it defines sequences based on the selection criterion it is given.
+In addition, with the \switch{list} switch,
+\pgm{pick} can be directed to list the numbers of the messages which
+satisfied the criterion, to the standard output.
+This is very handy for using \pgm{pick} in backquoted operations with the
+shell.
+\subsection{User-Defined Sequences}
+User-defined sequences allow the \MH/ user a tremendous amount of power
+in dealing with groups of messages in the same folder
+by allowing the user to bind a group of messages to a meaningful symbolic
+name.
+The user may choose any name for a message sequence,
+as long as it consists of alphanumeric characters and does not conflict with
+the standard \MH/ reserved message names (e.g., \arg{first}, etc).
+After defining a sequence,
+it can be used wherever a \MH/ command expects a \arg{msg} or \arg{msgs}
+argument.
+Although all \MH/ commands expand user-defined sequences as appropriate,
+there are two commands that allow the user to define and manipulate them:
+\pgm{pick} and \pgm{mark}.
+\subsubsection{Pick and User-Defined Sequences}
+Most users of \MH/ will use only the \pgm{pick} command.
+By giving the \switch{sequence~name} switch to \pgm{pick}
+(which can occur more than once on the command line),
+each sequence named is defined as those messages which \pgm{pick} matched,
+according the the selection criteria it was given.
+Hence,
+\example pick -from frated -seq fred\endexample
+finds all those messages in the current folder which were from
+\eg{frated},
+creates a sequence called \eg{fred},
+and then adds them to the sequence.
+The user could then invoke
+\example scan fred\endexample
+to get a \pgm{scan} listing of those messages.
+Note that by default,
+\pgm{pick} creates the named sequences
+before it adds the selected messages to the sequence.
+Hence, if the named sequence already existed,
+the sequence is destroyed prior to being re-defined
+(nothing happens to the messages that were a part of this sequence,
+they simply cease to be members of that sequence).
+By using the \switch{nozero} switch, this behavior can be inhibited,
+as in
+\example
+    pick -from frated -seq sgroup\\
+    pick -from fear -seq sgroup -nozero\\
+    pick -from freida -seq sgroup -nozero%
+\endexample
+which finds all those messages in the current folder which were from
+\eg{frated}, \eg{fear}, or \eg{freida},
+and defines the sequence called \eg{sgroup} as exactly those messages.
+These operations amounted to an ``inclusive-or'' of three selection
+criteria.
+Using \pgm{pick},
+one can also generate the ``and'' of some selection criteria as well:
+\example
+    pick -from frated -seq fred\\
+    pick -before friday -seq fred -nozero fred%
+\endexample
+This example defines the sequence called \eg{fred} as exactly those
+messages from \eg{frated} that were dated prior to \eg{friday}.
+\par
+\pgm{Pick} is normally used as a back-quoted command,
+for example,
+\example scan \bq{pick -from postmaster}\endexample
+Now suppose that the user decides that another command should be issued,
+using exactly those messages.
+Since,
+\pgm{pick} wasn't given a \switch{sequence~name} argument in this example,
+the user would end-up typing the entire back-quoted command again.
+A simpler way is to add a default sequence name to the \profile/ file.
+For example,
+\example pick: -sequence select -list\endexample
+will tell \pgm{pick} to always define the sequence \eg{select} whenever
+it's run.
+The \switch{list} is necessary since the \switch{sequence~name} switch sets
+\switch{nolist}
+whenever the former is encountered.
+Hence, this profile entry makes \pgm{pick} define the \eg{select}
+sequence and otherwise behave exactly as if it had no profile entry at all.
+\par
+Finally,
+previous versions of \pgm{pick} balked if a selection criterion was not given.
+The \mh4 version of \pgm{pick} does not, and merely matches the messages that
+were specified.
+This lets the \MH/ user type something such as
+\example show \bq{pick last:20 -seq fear}\endexample
+instead of typing
+\example
+    mark -add -nozero -seq fear last:20\\
+    show fear%
+\endexample
+\subsubsection{Mark and User-Defined Sequences}
+The \pgm{mark} command lets the user perform low-level manipulation of
+sequences,
+and also provides a well-needed debug facility to the
+implementors/developers/maintainers of \MH/ (the \MH/-hacks).
+In the future, a user-friendly ``front-end'' for \pgm{mark} will
+probably be developed to give the \MH/ user a way to take better
+advantage of the underlying facilities.
+\subsubsection{Public and Private User-Defined Sequences}
+There are two kinds of sequences: {\it public\/} sequences,
+and {\it private\/} sequences.
+{\it Public\/} sequences of a folder are accessible to any \MH/ user who
+can read that folder.
+{\it Private\/} sequences are accessible only to the \MH/ user who defined
+those sequences.
+By default,
+\pgm{pick} (and \pgm{mark\/}) create {\it public\/} sequences
+if the folder for which the sequences are being defined is writable by the
+\MH/ user.
+Otherwise, {\it private\/} sequences are created.
+This can be overridden with the \switch{public} and \switch{private} switches.
+\subsubsection{Sequence Negation}
+In addition to telling a \MH/ command to use the messages in the sequence
+\eg{seen}, as in
+\example refile seen +old\endexample
+it would be useful to be easily able to tell a \MH/ command to use all
+messages {\it except\/} those in the sequence.
+One way of doing this would be to use \pgm{mark} and define the sequence
+explicitly,
+as in
+\example mark -delete -zero seen -seq notseen\endexample
+which,
+owing to \pgm{mark\/}'s cryptic interpretation of \switch{delete} and
+\switch{zero},
+defines the sequence \eg{notseen} to be all messages not in the sequence
+\eg{seen}.
+Naturally,
+anytime the sequence \eg{seen} is changed,
+\eg{notseen} will have to be updated.
+Another way to achieve this is to define the entry
+\entry{Sequence-Negation} in the \profile/ file.
+If the entry was
+\example Sequence-Negation: not\endexample
+then anytime a \MH/ command was given \eg{notseen} as a \arg{msg} or
+\arg{msgs} argument,
+it would substitute all messages that are not a member of the sequence
+\eg{seen}.
+That is,
+\example refile notseen +new\endexample
+does just that.
+The value of the \entry{Sequence-Negation} entry in the profile can be
+any string.
+Hence,
+experienced users of \MH/ do not use a word,
+but rather a special character which their shell does not interpret
+(users of the \pgm{CShell} use a single carat, \eg{`\^'},
+while users of the Bourne shell use an exclamation-mark, \eg{`!'\/}).
+This is because there is nothing to prevent a user of \MH/ from defining a
+sequence with this string as its prefix,
+if the string is nothing but letters and digits.
+Obviously,
+this could lead to confusing behavior
+if the \entry{Sequence-Negation} entry leads \MH/ to believe that two
+sequences are opposites, by virtue of their names differing by the prefix
+string.
+\subsubsection{The Previous Sequence}
+Many times users find themselves issuing a series of commands on the same
+sequences of messages.
+If the user first defined these messages as a sequence,
+then considerable typing may be saved.
+If the user doesn't have this foresight,
+\MH/ provides a handy way of remembering the \arg{msgs} or
+\arg{msg} argument last given to a \MH/ command by the user.
+If the entry \entry{Previous-Sequence} is defined in the \profile/ file,
+then when the command finishes,
+it will define the sequence(s) named in the value of this entry as being
+defined as those messages that were specified.
+Hence, a profile entry of
+\example Previous-Sequence: pseq\endexample
+directs any \MH/ command that accepts a \arg{msg} or \arg{msgs} argument to
+define the sequence \eg{pseq} as those messages when it finishes.
+More than one sequence name may be placed in this entry,
+separated with spaces.
+The one disadvantage of this approach
+is that all \MH/ commands have to update the sequence information for
+the folder each time they run
+(although most commands read this information,
+usually only \pgm{pick} and \pgm{mark} have to write this information out).
+\section{Composition of Mail}
+Two new facilities have been added to give the \MH/ user greater power in
+composing and sending mail:
+the {\it draft folder},
+which allows a user to maintain a folder of message drafts;
+and, {\it draft pushing},
+which permits a user to \pgm{send} the current draft in the background.
+\subsection{The Draft Folder}
+The \pgm{comp}, \pgm{dist}, \pgm{forw}, and \pgm{repl} commands have two
+hidden switches, \switch{draftfolder~+folder} and \switch{draftmessage~msg}.
+If \switch{draftfolder~+folder} is used,
+these commands are directed to construct a draft message in the indicated
+folder.
+If \switch{draftmessage~msg} is not used, it defaults to \arg{new}
+(unless the user invokes \pgm{comp} with \switch{use},
+in which case the default is \arg{cur}).
+Hence, the user may have several message compositions in progress
+simultaneously.
+Now, all of the \MH/ tools are available on each of the user's message
+drafts
+(e.g., \pgm{show}, \pgm{scan}, \pgm{pick}, and so on).
+If the folder does not exist,
+the user is asked if it should be created (just like with \pgm{refile\/}).
+Also,
+the last draft message the user was composing is known as \arg{cur} in the
+draft folder.
+\par
+Furthermore,
+the \pgm{send} command has these switches as well.
+Hence, from the shell,
+the user can send off whatever drafts desired using the
+standard \MH/ \arg{msgs} convention with \switch{draftmessage msgs}.
+If no \arg{msgs} are given, it defaults to \arg{cur}.
+\par
+In addition,
+all five programs have a \switch{nodraftfolder} switch,
+which undoes the last occurance of \switch{draftfolder~folder}
+(useful if the latter occurs in the user's \MH/ profile).
+\par
+If the user does not give the \switch{draftfolder~+folder} switch,
+then all these commands act ``normally''.
+Note that the \switch{draft} switch to \pgm{send} and \pgm{show}
+still refers to the file called \eg{draft} in the user's \MH/
+directory.
+In the interests of economy of expression,
+when using \pgm{comp} or \pgm{send},
+the user needn't prefix the draft \arg{msg} or \arg{msgs} with
+\switch{draftmessage}.
+Both of these commands accept a \arg{file} or \arg{files} argument,
+and they will, if given \switch{draftfolder~+folder} treat these arguments
+as \arg{msg} or \arg{msgs}.%
+\nfootnote{This may appear to be inconsistant, at first,
+but it saves a lot of typing.}
+Hence,
+\example send -draftf +draft first\endexample
+is the same as
+\example send -draftf +draft -draftm first\endexample
+\par
+To make all this a bit more clear, here are some examples.
+Let's assume that the following entries are in the \profile/ file:
+\example
+    comp: -draftfolder +draft\\
+    dist: -draftfolder +draft\\
+    forw: -draftfolder +draft\\
+    repl: -draftfolder +draft\\
+    sendf: -draftfolder +draft%
+\endexample
+Furthermore,
+let's assume that the program \pgm{sendf} is a symbolic link in the user's 
+\file{\$HOME/bin/} directory to \pgm{send}.
+Then, any of the commands
+\example
+    comp\\
+    dist\\
+    forw\\
+    repl%
+\endexample
+constructs the message draft in the \eg{draft} folder using the \arg{new}
+message number.
+Furthermore,
+they each define \arg{cur} in this folder to be that message draft.
+If the user were to use the \pgm{quit} option at \whatnow/ level,
+then later on,
+if no other draft composition was done,
+the draft could be sent with simply
+\example sendf\endexample
+Or,
+if more editing was required,
+the draft could be edited with
+\example comp -use\endexample
+Instead,
+if other drafts had been composed in the meantime,
+so that this message draft was no longer known as \arg{cur} in the \eg{draft}
+folder,
+then the user could \pgm{scan} the folder to see which message draft in the
+folder should be used for editing or sending.
+Clever users could even employ \pgm{pick} to do the work:
+\example
+    comp -use \bq{pick +draft -to bug-mh}\\
+\noalign{\leftline{or}}
+    sendf \bq{pick +draft -to bug-mh}%
+\endexample
+Note that in the \pgm{comp} example,
+the output from \pgm{pick} must resolve to a single message draft
+(it makes no sense to talk about composing two or more drafts with one
+invocation of \pgm{comp\/}).
+In contrast,
+in the \pgm{send} example,
+as many message drafts as desired can appear,
+since \pgm{send} doesn't mind sending more than one draft at a time.
+\par
+Note that the argument \switch{draftfolder~+folder} is not
+included in the profile entry for \pgm{send},
+since when \pgm{comp}, et. al., invoke \pgm{send} directly,
+they supply \pgm{send} with the \unix/ pathname of the message draft,
+and {\it not} a \arg{draftmessage~msg} argument.
+As far as \pgm{send} is concerned,
+a {\it draft folder} is not being used.
+\par
+It is important to realize that \MH/ treats the draft folder like a standard
+\MH/ folder in nearly all respects.
+There are two exceptions:
+\underbar{first}
+under no circumstancs will the \arg{draftfolder~folder} switch cause the
+named folder to become the current folder.%
+\nfootnote{Obviously,
+if the folder appeared in the context of a standard \arg{+folder}
+argument to an \MH/ program, as in
+\example scan +draft\endexample
+it might become the current folder, depending on the context changes of the
+\MH/ program in question.}
+\underbar{Second},
+although conceptually \pgm{send} deletes the \arg{msgs} named in the draft
+folder,
+it does not call \entry{delete-prog} to perform the deletion.
+\subsection{What Happens if the Draft Exists}
+When the \pgm{comp}, \pgm{dist}, \pgm{forw}, and \pgm{repl} commands are
+invoked and the draft you indicated already exists,
+these programs will prompt the user for a reponse directing the program's
+action.
+In \mh4, the prompt is
+\begingroup
+    \smallertype
+    \example
+       ``/usr/src/uci/mh/mhbox/draft'' exists; replace, list, or quit?%
+    \endexample
+\endgroup
+The appropriate responses and their meanings are:
+\smallskip
+{\advance\leftskip by\parindent
+\item{\underbar{replace}:} deletes the draft and starts afresh.
+\item{\underbar{list}:} lists the draft.
+\item{\underbar{quit}:} leaves the draft intact and exits.
+\smallskip}
+\noindent
+In addition, if you specified \switch{draftfolder~folder} to the command,
+then one other response will be accepted:
+\smallskip
+{\advance\leftskip by\parindent
+\item{\underbar{new}:} finds a new draft,
+just as if \switch{draftmessage~new} had been given.
+\smallskip}
+\noindent
+Finally, the \pgm{comp} command will accept one more response:
+\smallskip
+{\advance\leftskip by\parindent
+\item{\underbar{use}:} re-uses the draft,
+just as if \switch{use} had been given.
+\smallskip}
+\subsection{The Push Option at\/{ }\whatnow/ Level}
+The \pgm{comp}, \pgm{dist}, \pgm{forw}, and \pgm{repl} commands take
+an additional option for the \whatnow/ query.
+The \pgm{push} option, which must be spelled out fully,
+directs the command to \pgm{send} the draft
+in a special detached fashion,
+with all normal output is discarded.
+If \pgm{push} is used and the draft can not be sent,
+then \MH/ will send the user a message,
+indicating the name of the draft file,
+and an explanation of the failure.
+Although using \pgm{push} calls \man{send}(1),
+the \pgm{send} command will consult the profile entry for \pgm{push}.
+\par
+The user can also invoke \pgm{send} from the shell with the \switch{push}
+switch,
+which makes \pgm{send} act like it had been \pgm{push\/}'d by one of the
+composition commands.%
+\nfootnote{Note that in this case,
+\pgm{send} consults the profile entry for whatever name it was invoked as,
+such as \pgm{sendf}.}
+\par
+The \pgm{send} program also has two other switches,
+\switch{unique} and \switch{nounique}.
+If \pgm{push\/}'d,
+then the \switch{unique} switch tells \pgm{send} to rename the draft file to
+a unique filename.
+This allows the user to have several drafts being sent simultaneously
+(after {\it push\/}ing one draft,
+another draft may be composed and edited immediately).
+The \switch{unique} switch,
+which is the default when \pgm{send} is \pgm{push\/}'d,
+is not really useful if you're using {\it draft folders},
+as the user generally gets a new message draft for each composition.
+Hence, users of the {\it draft folder} mechanism should put
+\example send: -nounique\endexample
+in their \profile/ file.
+This has the added advantage of making
+\example comp -use\endexample
+easy to use when a draft fails to be posted properly.
+\par
+By using \pgm{push}, the user can free the shell to do other things,
+because it appears to the shell that the \MH/ command has finished.
+As a result the shell will immediately prompt for another command,
+despite the fact that the command is really still running.
+Note that if the user indicates that annotations are to be performed
+(with \switch{annotate}),
+the annotations will be performed after the message has been
+successfully sent.
+This action will appear to occur asynchronously.
+Obviously, if one of the messages that is to be annotated is
+removed before the draft has been successfully sent,
+then when \MH/ tries to make the annotations,
+it won't be able to do so,
+and an error message will mysteriously appear on the user's terminal.
+\subsection{Options at\/{ }\whatnow/ Level}
+When using the \pgm{comp}, \pgm{dist}, \pgm{forw}, and \pgm{repl} commands at
+\whatnow/ level,
+the \pgm{edit}, \pgm{list}, \pgm{headers},
+and (for the \pgm{dist} and \pgm{repl} commands) the \pgm{display} options
+will pass on any additional arguments given them to whatever program they
+invoke.
+\par
+In addition,
+in \mh1 (the original Rand \MH/)
+and \mh2 (the first UCI version of \MH/),
+\MH/ used a complicated heuristic to determine if the draft should be deleted
+or preserved after an unsuccessful edit.
+In \mh3,
+\MH/ was changed to always preserve the draft,
+since \pgm{comp}, et. al.,
+could usually look at a draft, apply another set of heuristics,
+and decide if it was important or not.
+With the notion of a {\it draft folder}, 
+in which one by default gets a \arg{new} message draft,
+\mh4 has again re-implemented the edit deletion/preservation
+algorithm (with a minor bug-fix),
+to keep the draft folder from being cluttered with aborted edits.
+\par
+Also,
+note that by default,
+if the draft cannot be successfully sent,
+these commands return to \whatnow/ level.
+But, when \pgm{push} is used, this does not happen (obviously).
+Hence,
+if these commands were expected to annotate any messages,
+this will have to be done by hand, later on, with the \pgm{anno} command.
+\par
+Finally, if the \switch{delete} switch is given to the \pgm{quit} option,
+then these commands will inform the user of the name of the unsent draft file.
+\subsection{Posting of Mail}
+\mh4 does a few different things when mail is posted.
+\subsubsection{Signature}
+There's now a \entry{Signature} entry in the \profile/ file.
+If the \file{\$SIGNATURE} envariable is not set,
+then \pgm{send} will consult this profile entry to determine the
+personal name of the \MH/ user.
+This personal name is placed in the \eg{From:} field of the message.
+If this profile entry doesn't exist,
+then \pgm{send} will consult the file \file{\$HOME/.signature}.
+\subsubsection{Blind Carbon Copies}
+The \pgm{post} command now handles blind carbon copies in an entirely
+different fashion from the way they were handled in \mh3.
+In particular,
+the message sent to ``blind'' recipients contains minimal information in its
+headers,
+namely \eg{Date:},
+\eg{Message-ID:} (if \switch{msgid} was given),
+\eg{From:},
+\eg{Subject:} (if given in the message draft),
+and a standard blind carbon copy disclaimer.
+The body of the message sent to the blind recipients is simply the actual
+message sent to the ``sighted'' recipients.
+However,
+if the \switch{filter~filterfile} switch was given to \pgm{post},
+then the body of the message is given to \pgm{mhl} to be formatted with the
+named \arg{filterfile}.
+\subsubsection{Server Interaction}
+In \mh4, \MH/ supports a mail transport configuration which allows
+\pgm{post} to talk directly to an SMTP server.
+A possible extension of this,
+which looks particularly promising for when \MH/ is used on small
+workstations,
+is the ability to post mail on a different host,
+such as a ``mail relay''.
+In this way,
+the load on the local host may be reduced,
+and mail traffic may be handled more efficiently.
+\section{Folder Handling}
+Two new facilities have been added to give the \MH/ user greater power in
+manipulating folders:
+{\it relative folder addressing},
+which allows a user to shorten the typing of long folder names;
+and the {\it folder-stack},
+which permits a user to keep a stack of current folders.
+\subsection{Relative Folder Addressing}
+By default, when \arg{+folder} is given,
+and the folder name is not absolute
+(i.e., does not start with \file{/}, \file{./}, or \file{../}),
+then the \unix/ pathname of the folder is interpreted relative to the user's
+\MH/ directory.
+Although this mechanism works fine for top-level folders and their immediate
+sub-folders,
+once the depth of the sub-folder tree grows, it becomes rather unwieldly:
+\example scan +mh/mh.4/draft/flames\endexample
+is a lot of typing.
+\MH/ can't do anything if the current folder was \eg{+inbox},
+but if the current folder was, say, \eg{+mh/mh.4/draft},
+\MH/ has a short-hand notation to reference a sub-folder of the
+current folder.
+Using the address@hidden notation,
+the \MH/ user can direct any \MH/ command which expects a \arg{+folder}
+argument to look for the folder relative to the current folder instead of the
+user's \MH/ directory.
+Hence, if the current folder was \eg{+mh/mh.4/draft},
+then
+\example scan @flames\endexample
+would do the trick handily.
+In addition, if the current folder was \eg{+mh/mh.4/draft},
+\example scan @../pick\endexample
+would scan the folder \eg{+mh/mh.4/pick},
+since, in the \unix/ fashion,
+it references the folder \eg{pick} which is a sub-folder of
+the folder that is the parent of the current folder.
+Since most advanced \MH/ users seem to exhibit a large degree of locality
+in referencing folders when they process mail,
+this convention should receive a lot of use.
+\subsection{The Folder Stack}
+The {\it folder-stack\/} mechanism in \MH/ gives the \MH/ user a
+facility similar to the {\it CShell\/}'s directory-stack.
+Simply put,
+\example folder -push +foo\endexample
+makes \eg{foo} the current folder,
+saving the folder that was previously the current folder on the
+{\it folder-stack}.
+As expected,
+\example folder -pop\endexample
+takes the top of the {\it folder-stack\/} and makes it the current folder.
+Each of these switches lists the {\it folder-stack\/} when they execute.
+It is simple to write a {\it pushf\/} command as a shell script.
+It's one line:
+\example exec folder -push address@hidden
+Probably a better way is to link \pgm{folder} to your \file{\$HOME/bin/}
+directory under the name of \pgm{pushf} and then add the entry
+\example pushf: -push\endexample
+to the \profile/ file.
+\par
+The manual page for \man{folder}(1) discusses the analogy between the
+\pgm{CShell} directory stack commands and the switches in \pgm{folder}
+which manipulate the {\it folder-stack}.
+\section{Other Changes}
+This last section discusses the other,
+more program-specific changes made to \MH/.
+\subsection{Address Parsing}
+There's a new library program, \pgm{ap}, which parses addresses according to
+the rules that the \MH/ programs use.
+It's often useful for figuring out how \MH/ sees a particular address.
+The \pgm{rcvtrip} rcvmail hook,
+described at the end of this report,
+uses this facility.
+\subsection{Alternate Mailboxes}
+There's a new entry in the profile, \entry{Alternate-Mailboxes},
+which is read by \pgm{repl} and \pgm{scan} to determine which addresses in a
+messages are under the user's administration.
+Hence,
+\example
+    Alternate-Mailboxes: address@hidden, bug-mh
+\endexample
+says that the mailbox address@hidden
+and any mailbox whose local part is \eg{bug-mh}
+is read by the user.
+Hence, \pgm{repl} will not include them in the reply list,
+and \pgm{scan} will act accordingly if it encounters a message which is from
+any of these addresses.
+A current restriction is that the hostnames given must be the ``official''
+hostnames for the mailboxes,
+as local nicknames for hosts are not replaced with their official site names.
+\subsection{Annotation}
+The \pgm{anno} command no longer prompts for a \eg{text} component
+if the \switch{text~body} switch isn't given.
+\subsection{More on Folder Handling}
+If \pgm{folders} 
+(or \pgm{folder} when invoked with the \switch{all} switch)
+is given a \arg{+folder} or \arg{msg} argument,
+then it will set the current folder and/or message
+(in previous versions of \MH/,
+\pgm{folders} ignored any \arg{+folder} or \arg{msg} arguments).
+In addition,
+the top-level folders of the current folder will be listed
+(if \switch{norecurse} is in effect),
+or the current folder will be listed recursively
+(if \switch{recurse} was given).
+\subsection{Scanning}
+The \pgm{scan} and \pgm{inc} commands now have a \switch{size} switch
+(and a complementary switch, \switch{nosize}),
+which indicate if the {\it scan listing\/} should include the size of the
+message in bytes.
+\par
+Furthermore,
+the fields in the {\it scan listing\/} have been compressed a bit to allow
+more of the \eg{Subject} and \eg{Body} portions of the listing to appear.
+\par
+Finally,
+if \pgm{scan} encounters a message without a date field,
+rather than leaving that portion of the {\it scan listing} blank,
+as had been done in previous versions of \MH/,
+the date is filled-in with the last write date of the message,
+and post-fixed with a `*'.
+This is particularly handy for scanning a {\it draft folder},
+as message drafts usually aren't allowed to have dates in them.
+\subsection{BBoards Support}
+The \pgm{bbr} command now uses the name it was invoked with as its prompting
+string.
+To override this,
+the \MH/ user can specify the \switch{prompt~string} switch to \pgm{bbr}.
+\par
+The \pgm{bbc} command now lists the \eg{last update time} of a {\it BBoard},
+instead of the \eg{local leaders} when \switch{topics} is used without
+\switch{verbose}.
+The \eg{local leaders} are now listed when \switch{verbose} is given with
+\switch{topics}.
+\subsection{RcvMail Support}
+The \pgm{rcvcron} and \pgm{rcvtty} are now standard in all \mh4
+configurations.
+Further, there's a shell script, \pgm{rcvtrip},
+that demonstrates the power (and utility) of a {\it hook\/} operating in the
+\MH/ environment.

+\title{MH for MM Users}
+\author{Mary Hegardt \and Tim Morgan}
+\maketitle
+
+\section{Introduction}
+
+This document is another in a continuing series on use of the \MH/ mail
+system at UCI.  It is intended for those users accustomed to the \MM/ ``user
+agent'' (mail program) under \tops20/ and who are already familiar with
+network mail, but who may not be experienced \unix/ users.  For an
+introduction to \MH/, see ``MH For Beginners'' by Mary
+Hegardt and Tim Morgan.  For complete, detailed information on the \MH/
+system, see {\sl The Rand MH Message Handling System: User's Manual\/} by
+Marshall~T. Rose and John~L. Romine. Both documents are available for
+Xeroxing in suite CS408.
+
+\subsection{UNIX Versus Tops-20}
+
+The \unix/\footnote{\unix/ is a trademark of AT\&T Bell Laboratories}
+paradigm is that each command, or program, should perform only one
+function.  An extension of this idea is that the operating system
+implements only those functions which are necessary, but it does so in
+a very general way so that programs may still accomplish their functions.
+This philosophy probably evolved because the original versions
+of \unix/ ran on PDP-11 minicomputers which had only a small memory
+space for each process.
+
+Consequently, all commands in \unix/, with a very few exceptions, are
+in actuality programs.  On \tops20/, in contrast, many of the most frequently
+used commands are built into the user's shell, or {\em exec.}  Both the
+Exec and {\it csh,} which is typically the user's command interface on
+\unix/, will accept and parse command lines, attempting to invoke a command
+as a program if it is not one of the built-in commands.  \unix/ and \tops20/
+are surprisingly similar internally: the use of the shell, separate
+processes for each command or program to execute, standard input and output
+for each program, and many other ideas are common to both operating
+systems.  Users should be familiar with the capabilities of the shell,
+which is described in the document ``Introduction to the Csh.''
+
+\subsection{The MH User Interface}
+
+The \MH/ mail ``user agent'' is different from most other mail systems.
+\MM/, for example, is a {\em monolithic\/} system because one program
+implements all the mail-related functions.  The disadvantages of monolithic
+systems are that (a)~they are large, so they tend to put more burden on the
+computer system, and (b)~they allow for much less flexibility.  In contrast,
+\MH/ implements each mail command as a separate program: there is no single
+program called {\it mh.}  This approach facilitates interspersing mail
+commands with other, perhaps unrelated, commands.
+
+Another unique feature of \MH/ is that it takes advantage of the facilities
+provided by the operating system.  Most mail agents, such as \MM/, maintain
+a file containing the user's mail in a special, usually undocumented, format.
+When a message is deleted, \MM/ must take care of compacting the mail file.
+It must be able to distinguish the separate messages contained in the file.
+\MM/ must also implement a simple text editor to allow the user to enter
+and modify a message while it is being composed.
+These functions are essentially those provided by the operating system when
+separate files are stored within a directory.  Therefore, the approach
+taken by \MH/ is that
+each message is kept in a separate file.  This file simply contains the
+message, with no other special formatting characters or requirements.
+All the messages are stored within a normal \unix/ directory.  This approach
+makes it easy to add new \MH/ commands, to edit messages using standard
+text editors, etc.
+
+All your \MH/ related files are stored in a directory within your home
+directory.  Usually this directory is called {\tt Mail} or {\tt mhbox},
+although you are free to name it as you choose.  Another file in your home
+directory called \verb|.mh_profile| is equivalent to the {\tt MM.INIT} file
+under \MM/.  It contains all the options which you prefer for the various
+\MH/ commands.  It also contains the name of the \MH/ directory and the
+name that you want on your outgoing mail in the {\tt From:} field (your
+``{\em signature\/}'').
+
+\section{Getting Started}
+
+\subsection{Incorporating Mail}
+
+Another important difference between \MM/ and \MH/ is the concept of the
+{\em maildrop\/} file.  Under \tops20/, the mail transport system delivers
+new messages directly into the recipient's {\tt MAIL.TXT} file, where they may
+then be processed with \MM/.  In contrast, the \unix/ mail transport system,
+called {\it MMDF-II,} makes no assumptions about the user agent used by the
+recipient.  Instead, it puts all new mail into a special file called the
+{\em maildrop.}  This file is in the \verb|/usr/spool/mail| directory.
+When you log in, if there is new mail for you in your
+maildrop, you will be so notified by the message
+
+       \oneline{You have new ZOTnet mail -- type inc (or mail)}
+
+When you are ready to process this new mail, you may type the command
+
+       \command{inc}
+
+(``incorporate'') which will copy the new mail into separate files, one per
+message, stored in your ``inbox'' folder.  A folder is a subdirectory
+beneath your \MH/ directory which is used to store related messages.
+Additional information on folders is given in Section~\ref{Folders},
+page~\pageref{Folders}.  The
+``inbox'' is a distinguished folder because by default {\it inc\/} will
+always copy new mail into that folder, removing it from the maildrop.
+
+If this is the first time you have used {\it inc\/} or any other \MH/
+command, the {\it mh-install\/} program  will inform you that it is
+creating your {\tt Mail} directory. It will also create
+the ``inbox'' folder directory, and \verb|.mh_profile|.  
+
+\subsection{Message Numbers}\label{Scan}
+
+As {\it inc\/} processes each message, it prints a ``scan'' listing showing
+the message number, the date the message was sent,
+the name of the sender, the subject, and sometimes the initial part of the
+text of the message.  A ``scan'' listing is thus similar to the output of
+the {\tt HEADERS} command in \MM/.  Each message within a folder is given a
+number, starting with 1, by which it can be referenced.  {\it
+Inc\/} will display the numbers assigned to each new message in its ``scan''
+listing.
+
+As in \MM/, there is a ``current message'' number which usually identifies the
+message most recently manipulated by the user.  With most \MH/ commands,
+this will be the default message if no messages are explicitly specified in
+a command.  {\it Inc\/} makes the first new message the current message,
+which is indicated by a ``{\tt+}'' character in the scan listing, just after
+the message number.
+
+Many \MH/ commands take a list of messages to process. A message designation
+is either a single message number, two message numbers separated by a dash.
+The dash format indicates a range of messages including the endpoints. A
+message list consists of one or more message designations separated by
+spaces. For example, messages 11 through 15 and message 17 may be indicated
+by typing
+
+       \oneline{11-15 17}
+
+as the argument to some command.  There are also several predefined names
+for messages or lists of messages which may be used in place of message
+numbers:
+
+\bigskip
+\begingroup\parskip=0pt
+\def\titem[#1]{\par\hangafter=1\hangindent=.7in\noindent
+       \hbox to\hangindent{\it\hfil#1\qquad}\ignorespaces}
+
+\titem[cur] The current message (the last one that was handled).  Equivalent
+  to ``.'' or ``{\tt CURRENT}'' in \MM/.
+\titem[next] The next message 
+\titem[prev] The previous message
+\titem[first] The first message in the current folder.
+\titem[last] The last message in the folder.  Equivalent to {\tt\%} or
+  {\tt*} in \MM/.
+\titem[all] All messages ($\it first-last$).  Same as in \MM/.
+\endgroup
+
+It is also possible for you to define your own named {\em sequences\/} of
+messages.  See the {\it pick\/} command description for more details.
+
+\section{Processing Messages}
+
+This section contains a list of the common \MM/ commands and their
+equivalents in the in \MH/ mail system.  A short textual note describes how
+the \MH/ commands differ from their \MM/ counterparts.
+
+\subsection{Listing Messages}
+
+As mentioned in Section~\ref{Scan},
+the {\it scan\/} command may be used to summarize the
+messages in a folder, similar to the {\tt HEADERS} command in \MM/.  Unlike
+most \MH/ commands, however, {\it scan\/} defaults to {\em all\/} the
+messages in the current folder unless you specify one or messages on the
+command line to be scanned.  So simply typing
+
+       \command{scan}
+
+is equivalent to typing {\tt HEADERS ALL} (or {\tt H A}) in \MM/.
+
+\subsection{Reading Mail}
+
+Unlike the {\tt READ} command in \MM/, in \MH/ there is no special
+mail-reading mode (indicated in \MM/ by the {\tt R>} prompt).
+The command to read messages in \MH/ is {\it show.} If no message list is
+specified, then the current message is displayed.  The message is displayed
+by your ``showproc'', as specified in the \verb|.mh_profile|, described
+in Section~\ref{Tailoring}.
+Normally, your ``showproc'' will be {\it more\/} or {\it mhless.}
+Both of these programs will display your messages one screenful at a time.
+You press the \fbox{space bar} on your terminal to see the next screenful,
+or the \fbox{return} key to see the next line.
+
+The command
+
+       \command{show next}
+
+(which will display the first message following the current message in the
+current folder) can be abbreviated as simply
+
+       \command{next}
+
+Similarly, the command ``{\tt show prev}'' can be abbreviated as simply ``{\tt
+prev}''.
+
+To get a paper copy of a mail message, take the output from the {\it show\/}
+command and pipe it into the {\it imprint\/} command.
+
+       \command{show 5 | imprint}
+
+See the manual page for {\it imprint\/} for more information.
+
+
+\subsection{Deleting Messages}
+
+The equivalent of the {\tt DELETE} command in \MM/ is {\it rmm\/} in \MH/
+(remove messages).  It acts on the current message unless messages are
+specified on the command line. Unlike \MM/, the deleted messages will
+no longer show up in a ``scan'' listing. But the messages are not 
+completely removed; they are renamed to have a comma
+prepended to the name of the file containing the message within its folder
+directory.  Therefore, if you need to recover a message, it is possible to
+go into the directory and rename the message back.  Be careful in doing this
+not to overwrite a new message with the same message number!  It is a \unix/
+convention that files whose names begin with a comma will be removed from
+disk ({\em expunged\/}) early each morning. Therefore, your deleted
+messages will be available for the rest of the day, unless you remove another
+message subsequently which has the same message.  Then the previously deleted
+message is gone.
+
+\subsection{Replying to Mail}
+
+The equivalent of the {\tt REPLY} command in \MM/ is {\it repl\/} in \MH/.
+{\it Repl\/} may be given the number of the message to which you wish to
+reply, or it will default to the current message.  When replying in \MM/,
+you are prompted asking if you wish to reply to all the recipients of the
+message to which you are replying, or only to its sender.  In \MH/, normally
+the reply will be constructed to be sent to all the recipients.  You may
+select which recipients receive copies of your reply by using the {\tt
+-query} option on {\it repl,} or by putting this option in your
+\verb|.mh_profile|, as described in Section~\ref{Tailoring}. If you
+wish a reply to go to everyone but yourself, you can 
+use \verb|repl -nocc me|.
+
+\subsection{Sending Mail}
+
+The equivalent of the {\tt SEND} \MM/ command is {\it comp\/} (``compose'')
+in \MH/.  These two commands are fairly similar, except that the recipient of
+the message cannot be specified on the {\it comp\/} command line.
+The {\it comp\/} program invokes a simple editor called {\it prompter\/}
+which will prompt you for the {\tt To:}, {\tt Cc:},
+and {\tt Subject:} fields of the message.  Then a line of dashes is typed,
+and you may enter the body of your message (its {\em text,} in \MM/ terms).
+When you are finished, type \fbox{ctrl}--D (equivalent to typing \fbox{ESC} or
+control-Z in \MM/).  Then you'll receive the prompt
+
+       \oneline{What now?}
+
+which is similar to \MM/'s {\tt S>} prompt.  You may receive a list of the
+options that you have at this point by typing ``{\tt?}'' followed by
+\fbox{return}.  Here is a short list of the options and their meanings.
+Notice that, unlike \MM/, there are very few commands to modify the message
+(such as the {\tt TEXT}, {\tt TO}, {\tt CC}, etc., commands which may be
+typed at the {\tt S>} prompt in \MM/).  In place of these commands, you use
+the {\tt edit} command to invoke your favorite text editor on the message,
+and you use it to make the equivalent changes.  You also use your editor
+to include other files into the body of the message, rather than using
+control-B, as in \MM/.  One additional use of the {\tt edit} command is
+for spelling checking.  In \MM/, you may use the command {\tt SPELL} 
+for this purpose.  
+In \MH/, you type ``{\tt edit spell}''\footnote{ Actually, any
+program named after the ``{\tt edit}'' command will be invoked with
+whatever arguments you have given and a path to the file containing
+the message you are editing.} instead.  This will
+cause the spelling checker to be run, giving you a list of the possibly
+misspelled words in your message.
+
+\bigskip
+
+\begingroup
+\def\titem[#1]{\par\hangafter=1\hangindent=1.4in\noindent
+       \hbox to\hangindent{\hfil#1\qquad}\ignorespaces}
+
+\titem[\tt edit \it editor\/] Edit the message using the specified
+                               editor.  When you exit, you will be
+                               back at \verb|What now?|.
+
+\titem[\tt list] Shows the message you just typed
+
+\titem[\tt whom -check] Verifies that the addresses you have
+                               used are valid as far as our system
+                               can tell
+
+\titem[\tt send] Sends the message to the recipients
+
+\titem[\tt push] Sends the message in the background
+
+\titem[\tt quit] Quits without sending the message.
+                               Saves the text of the message as
+                               a ``draft''. Type \verb|comp -use| to
+                               get back to that draft later.
+
+\titem[\tt quit -delete] Quit, throwing away the draft
+\endgroup
+
+\bigskip
+
+\subsection{Forwarding Mail}
+
+The {\it forw\/} command is used in \MH/ to forward messages.  It will take
+a list of messages on the command line to be forwarded, or it will default
+to the current message if none are specified.  It will prompt you like {\it
+comp\/} does for the {\tt To:}, {\tt Cc:}, and {\tt Subject:}\ fields.  Note
+that, unlike \MM/'s {\tt FORWARD} command, {\it forw\/} will not construct a
+subject line automatically.  Also as with {\it comp,} you will have the
+opportunity to add additional text to the message(s) which you are
+forwarding, ended with a control-D.  
+
+\subsection{Resending Mail}
+
+The equivalent of the {\tt RESEND} command in \MM/ is the {\it dist\/}
+(``distribute'') command in \MH/.  {\it Dist\/} works very much like the
+{\it forw\/} command, except that the prompts will be {\tt Resend-To:},
+{\tt Resend-Cc:}, etc. After filling in the headers, a line of dashes
+is typed giving the impression that additional text can be entered.
+Nothing could be further from the truth; if you add any text at this
+point the {\it dist\/} will fail.  Your only opportunity to add text
+is in the {\tt Resend-Note:} field.
+
+\section{Advanced Topics}
+
+\subsection{Selecting Messages}
+
+In \MM/, you may use several reserved command words to select messages
+in place of an explicit list of message numbers.  For example, you can
+type ``{\tt DELETE FROM SMITH}'' to remove all the messages from a user named
+``Smith''.  Rather than building such a capability into each \MH/ program
+which can process message lists, a special program called {\it pick\/} is
+used instead.  Just as there are predefined sequences of messages, such as
+``{\tt all}'', ``{\tt cur}'', etc., you may use {\it pick\/} to define your
+own sequences.  {\it Pick\/} is capable of selecting messages from a folder
+based on the {\tt To:}, {\tt From:}, {\tt Subject:}, {\tt Cc:}, or {\tt
+Date:} fields, or by searching the body of the message.  The patterns to be
+searched for may include full regular expressions (see the ``man'' page for
+{\it ed(1)\/} for more information) or simple strings.
+
+{\it Pick\/} may be used in one of two ways.  First, it may output the
+sequence of message numbers which match the search parameters.  Using the
+backquoting mechanism of the shell, these message numbers may then become
+the arguments to other \MH/ programs.  The second way to use {\it pick\/} is
+to have it define a new sequence name which will be the messages which were
+selected.  Only this second method of using {\it pick\/} will be described
+here; see {\it pick(l)\/} if you wish to use the first method.
+
+In your \verb|.mh_profile|, add the line
+
+       \oneline{pick: -seq sel}
+
+Then each time you use the {\it pick\/} command, it will define the
+resulting sequence of messages to be called ``sel''.  Then to ``pick'' all
+the messages in the current folder which are from ``Smith'', just type
+
+       \command{pick -from smith}
+
+To see a summary of those messages, type
+
+       \command{scan sel}
+
+Then to the remove the messages, type the command
+
+       \command{rmm sel}
+
+You can {\it pick\/} messages according to any of the headers ({\tt -to
+-from -subj -cc {\rm or} -date}) or just search all the messages for a given
+word ({\tt -search}).
+
+\subsection{Customizing Your Mail Environment}\label{Tailoring}
+
+In \MM/, you use the {\tt PROFILE} command to tailor your mail environment.
+This command writes a file called {\tt MM.INIT} in your home directory which
+is then read by subsequent executions of \MM/.  In the \MH/ system, the file
+\verb|.mh_profile| serves the same purpose.  It is edited with any normal
+text editor, rather than using a special-purpose command to modify it.  The
+format of the file is line oriented, one line per \MH/ program or \MH/
+option to be set.  The only required line in the profile is the name of the
+primary \MH/ mail directory, which is by default {\tt Mail}. This
+information is specified by the line
+
+       \oneline{Path: Mail}
+
+The textual name you would like to have on your outgoing mail is specified
+by the {\tt Signature:} line.  For example,
+
+       \oneline{Signature: Mary Hegardt}
+
+The BBoards which you like to read should also be listed in the
+\verb|.mh_profile| (see Section~\ref{BBoards}, page~\pageref{BBoards}, for
+additional information).  For example, if you read the ``system'' BBoard
+(where all important announcements are posted), as well as ``whimsey''
+and ``imagen-users'' BBoards, your \verb|.mh_profile| should contain the line
+
+       \oneline{bboards: system whimsey imagen-users}
+
+Other options may be specified on a per-program basis.  The format for these
+lines is the same.  First, the program name is given followed by a colon.
+Then any flags which are to be the default options for that program are
+given.  Here is a short list of the most common options which you may want
+to set in your \verb|.mh_profile|:
+
+       \oneline{showproc: mhless}
+
+The {\it showproc\/} is the program used to show messages to you.  By
+default, it is the {\it more\/} command.  {\it Mhless\/} is the same as
+{\it more\/} except that it omits the headers of the messages which you
+indicate that you wish not to see.  Type
+
+       \command{man mhless}
+
+for more information about this program.
+
+       \oneline{msh: -scan}
+
+Selecting this option causes an automatic scan of new messages on BBoards to be
+made when reading BBoards with {\it bbc,} similar to the scan listing
+produced by {\it inc.}
+
+       \oneline{repl: -query}
+
+causes {\it repl\/} to ask for each address in the message being replied to
+if it should be included in the {\tt To:} or {\tt Cc:} fields of the reply
+being composed.
+
+       \oneline{pick: -seq sel}
+
+This line will cause messages ``picked'' by the {\it pick\/} command to be
+put into a sequence named ``sel''.  This sequence name may then be used
+just as the built-in sequences (``last'', ``first'', etc.).
+
+\subsection{Aliases}
+
+Using \MH/, you may specify your own private mail aliases.  This feature
+allows you to store lists of addresses or long internet addresses of people
+with whom you frequently correspond in one file, and then to address them
+using short mnemonic names.  Typically, you will call your alias file ``{\tt
+aliases}''; it must be stored in your \MH/ directory.  The format of this
+file is simple. The alias is given, followed by a colon, followed by one or
+more legal mail addresses separated by commas.  For example, you might for
+some reason have an alias for all the users named ``Rose'' in the ICS
+department:
+
+       \oneline{roses: prose, srose, mrose, drose}
+
+In addition to your ``{\tt aliases}'' file, you will need to modify your
+\verb|.mh_profile| in order to use aliases.  You should add the flag
+``{\tt -alias aliases}'' to the entries for the commands {\it ali, whom,
+send,} and {\it push,} creating entries for these programs if they aren't
+already in your \verb|.mh_profile|.
+Now, messages addressed to ``{\tt roses}'' will be distributed to all
+the people listed in the alias.
+
+The {\it ali\/} command is used to show you what an alias expands to.
+You just type
+
+       \comarg{ali}{alias}
+
+and {\it ali\/} will respond with the expansion of the {\it alias.}  {\it
+Ali\/} searches the system aliases file in addition to your private ones.
+
+\subsection{Blind Lists}
+
+There are two different types of so-called ``blind addressing'' of messages.
+Users of \MM/ may already be familiar with the ``Blind Carbon Copy'', or
+{\tt BCC:} field.  It allows you to add recipients to your message just
+like those who are CC'd, but the normal recipients will not see that the
+BCC recipients were copied on the message, their replies will not go to the
+blind recipients, and the blind recipients cannot (easily) reply to the
+message.
+
+The second type of blind mailing is actually called a ``group address list'',
+although it is commonly referred to as a ``blind list''.
+The format of this type of address is
+
+       \oneline{{\it phrase\/}: {\it address\_list\/};}
+
+where the ``{\it phrase\/}'' is any English phrase of one or more words,
+and the {\it address\_list\/} consists of one or more addresses separated by
+commas.  The recipients of a message addressed in this fashion will
+see simply
+
+       \oneline{{\it phrase\/}: ;}
+
+so when they reply to the message, their reply will come only to the sender
+(or the {\tt Reply-To:} field, if one was specified), rather than going to
+all the recipients of the original list. For example, to use a group
+address list for the ``{\tt roses}'' alias you would type:
+
+       \oneline{To: People Named Rose: roses;}
+
+This type of group address is very
+useful for making up lists of related people, such as all the people working
+on a particular research project.
+
+\subsection{Folders}\label{Folders}
+
+As mentioned previously, folders are directories within your \MH/ directory
+used to store related messages.  There is no equivalent of the folder
+concept in the \MM/ system. Usually, you will use only the folder ``inbox'',
+so you won't have to worry about folders.  However, if you process a large
+volume of mail, then folders become invaluable in managing the messages
+which you wish to keep for future reference.
+
+Just as there is a ``current message,'' \MH/ maintains a ``current folder,''
+which will normally be ``inbox''.  You can change folders either by
+specifying the folder on the command line of \MH/ programs which take a
+list of messages as an argument, or by using the {\tt folder} command:
+
+       \command{folder +{\it folder\_name}}
+
+In general, the folder name is indicated by a ``{\tt+}'' sign followed
+immediately by the folder name, all preceeding any list of messages. For
+example, you may read the most recent message in a folder called
+``job\_offers'' using the command
+
+       \command{show +job\_offers last}
+
+This command will have the side-effect of setting the current folder to be
+``job\_offers''. You may move messages from the current folder into the
+``job\_offers'' folder using the command
+
+       \comarg{refile +job\_offers}{messages}
+
+where, as usual, the {\it messages\/} list will default to the current
+message in the current folder if none are specified.  Note that, in contrast
+with the {\it show\/} command and most other \MH/ commands, the {\it
+messages\/} are {\em not\/} considered to be in the folder ``job\_offers''.
+You may obtain a summary of all your folders by typing the command
+
+       \command{folders}
+
+When you remove messages from a folder using the {\it rmm\/} command,
+the deleted messages will show up as a ``hole'' in the message numbering.
+The command
+
+       \command{folder -pack}
+
+will cause all the messages within one folder to be renumbered starting
+with~1. Similarly, the command
+
+       \command{folders -pack}
+
+will do the same thing for all your folders.
+
+To remove an empty folder, use the command
+
+       \command{rmf +{\it folder}}
+
+\subsection{Reading BBoards}\label{BBoards}
+
+Two special-purpose programs are utilized in reading BBoards.  The first is
+{\it bbc,} which is used to check a list of BBoards for new messages.
+The list of messages may be given on the command line, or if not, it will be
+taken from the {\tt BBoards:} list in your \verb|.mh_profile|.  You may
+obtain a list of all the available BBoards by typing the command
+
+       \command{bbc -topics}
+
+For each BBoard with unseen messages, {\it bbc\/} will invoke the \MH/
+shell, {\it msh,} whose prompt is
+
+       \oneline{(msh)}
+
+The {\it msh\/} program allows you to read BBoard mail as if it were normal
+messages in one of your folders.  Almost all the \MH/ commands will work
+just as the normally do.  Typing the command ``{\tt quit}'' to {\it msh\/}
+causes it to stop reading the current BBoard and go on to the next one
+containing unseen messages, or to exit if there are no more such BBoards.
+Typing control-D causes {\it msh\/} to exit unconditionally.  The command
+{\tt mark} followed by a message number causes {\it msh\/} to act as if you
+have seen that message and all previous ones.
+
+\subsection{Checking for Mail}
+
+Under \unix/, there are about a dozen different ways to check for new mail.
+The easiest way to do it is to set the {\it csh\/} variable named ``mail''
+to tell {\it csh\/} to check for new mail for you periodically.  To do this,
+add the line
+
+       \oneline{set mail=(60 /usr/spool/mail/\$USER)}
+
+to your {\tt .login} file in your home directory.  This command says to
+check for mail if {\it csh\/} is about to prompt you with a {\tt\%} sign,
+and if it has been at least 60 seconds since it last checked for mail.
+The advantage of this method of mail notification, besides simplicity, is
+that you will never be interrupted by a mail notification.  You will only be
+notified of new mail when you are between commands, when the shell is about to
+prompt you.
+
+If you desire asynchronous mail notification, which will print to your
+terminal regardless of what you are currently doing, you may make use of a
+``Receive Mail Hook'' called ``rcvtty''.  To do this, create a file in your
+home directory called ``{\tt .maildelivery}''.  In this file, put the line
+
+       \oneline{* - pipe R /usr/uci/lib/mh/rcvtty}
+
+Then each time new mail arrives, you will receive a one-line ``scan''
+listing of the mail if your terminal is world-writable. For more information
+on ``maildelivery'' files, type:
+
+       \command{man 5 maildelivery}
+
+
+\subsection{Saving Drafts}
+
+Normally when you use {\it comp,} it creates the message being composed in a
+file called ``{\tt draft}'' in your \MH/ directory. If you use the ``{\tt
+quit}'' option at the ``{\tt What now?}'' prompt, this file will remain
+there.  You may later use the command
+
+       \command{comp -use}
+
+to resume composing the message.
+
+If you begin composing a new message and there is already a ``draft'' file,
+you will be asked for the disposition of this file.  Typing {\tt?}
+\fbox{return} will give you a list of the options at this point.  Normally
+you will either {\tt replace} (delete) the old draft and begin
+a new one or {\tt use} the old one.
+
+The {\tt -file} switch to {\it comp\/} may be used to specify the name of a
+draft other than ``{\tt draft}''.  For example, one might type
+
+       \command{comp -file mary}
+
+to begin composing a message maintained in the draft file ``{\tt mary}''.
+Typing
+
+       \command{comp -file mary -use}
+
+would cause {\it comp\/} to resume composing this same draft after a
+``{\tt quit}'' command to the ``{\tt What now?}'' prompt.
+
+Very advanced users of \MH/ maintain multiple draft files in a {\it draft
+folder.}  This is a normal folder which holds all your drafts, rather than
+having just one draft in your \MH/ directory named ``{\tt draft}''.  If you
+feel that you need to use draft folders, you should consult the {\sl MH
+User's Manual\/} for additional information.

+
+Tue Oct 23 12:35:58 1984  /mtr (agent: Marshall Rose) <address@hidden>
+
+       conf/config/mts.c, mts/mts.h: remove the mbx_lock() and mbx_unlk()
+       routines and replace them with the lock-and-open routines
+       lkopen(), lkclose(), lkfopen(), and lkfclose().  lkopen() acquires
+       an exclusive lock on the named file (which *must* exist) and then the
+       appropriate open.  lkclose() releases the lock and closes the
+       file.  lkfopen() is to lkopen() as fopen() is to open().  lkfclose()
+       is to lkclose() as fclose() is to close().  I had to do all this
+       so with 4.2BSD we can use flock to do the locking instead of the
+       link/unlink business.

+       uip/mhlsbr.c: support libpath for system-wide forms.
+       config/mh.h,mf/mf.c,sbr/getusr.c,uip/post.c: add -DNRTC for MAILID
+           support
+       uip/replsbr.c: don't panic if the host for the sender/from field
+           is unknown.
+       uip/{send,whom}.c: forgot to use m_draft() instead of m_maildir(draft).
+       sbr/m_draft.c: fix things up for show -draft.
+       uip/show.c: add a "-form formfile" switch.  Also, support for -draft
+           to reflect draftfolders.

+
+Wed Oct 24 21:46:22 1984  /mtr (agent: Marshall Rose) <address@hidden>
+
+       conf/config/config.c, config/mh.h: add libpath() which looks first
+           in m_maildir and then etcpath for the file.  Get rid of the
+           std* variables since libpath() now does the same thing.
+       With libpath, we now search m_maildir and then etcpath for
+           alias files for send and whom, form files for comp, dist, forw,
+           and repl, and filter files for forw and mhl.

+           implicit calls to m_getdefs ().
+       {sbr/m_getdefs,uip/rmf}.c: make mp->others checking a bit smarter
+           for #ifdef UCI.

+
+Mon Oct 29 19:23:10 1984  /mtr (agent: Marshall Rose) <address@hidden>
+

+           defeating setbbfile().  They weren't even needed since the
+           first thing that bbc does (even before parsing arguments) is
+           to call setbbent().
+       uip/show.c: force -noformat, -noheader, and -nopr to be at least
+           three characters for recognition.
+       uip/post.c: when invoking fileproc, add a '+' only if it doesn't

+
+
+Tue Oct 30 18:59:45 1984  /mtr (agent: Marshall Rose) <address@hidden>
+
+       mf/mf.c: very minor clean-up of isfrom().

+
+
+Tue Oct 30 21:30:38 1984  /mtr (agent: Marshall Rose) <address@hidden>
+
+       tws/dtimep.c: parse ctime(3) strings, since some fool hosts
+           actually permit that to get into the Internet.
+
+
+Tue Oct 30 22:14:19 1984  /mtr (agent: Marshall Rose) <address@hidden>
+
+       uip/post.c: if we get an address-bearing field without any address,
+           just ignore it instead of complaining about it.

+\section{Acknowledgements}
+The \MH/ system described herein is based on the original Rand \MH/ system.
+It has been extensively developed (perhaps too much so) by Marshall Rose and
+John Romine at the University of California, Irvine.
+Einar Stefferud, Jerry Sweet, and Terry Domae provided numerous suggestions
+to improve the UCI version of \MH/.
+
+\section{Disclaimer}
+The Regents of the University of California wish to make it known that:
+\bigquote
+Although each program has been tested by its contributor,
+no warranty, express or implied,
+is made by the contributor or the University of California,
+as to the accuracy and functioning of the program
+and related program material,
+nor shall the fact of distribution constitute any such warranty,
+and no responsibility is assumed by the contributor
+or the University of California in connection herewith.
+\endbigquote
+
+\section{Conventions}
+In this document,
+certain \TeX -formatting conventions are adhered to:
+\smallskip
+{\advance\leftskip by\parindent
+\item{1.} The names of \unix/ commands, such as \pgm{comp},
+are presented in {\it text italics}.
+\item{2.} Arguments to programs, such as \arg{msgs},
+are presented in {\tt typewriter style} and delimited by single-quotes.
+\item{3.} \unix/ pathnames and envariables,
+such as \file{/usr/uci/} and \file{\$SIGNATURE},
+are presented in {\sl slanted roman}.
+\item{4.} Text presenting an example, such as
+\example comp\ -editor\ zz\endexample
+is presented in {\tt typewriter style}.
+\smallskip}
+
+\bop\section{General Changes}
+The author is pleased to announce that there are actually very few
+user-visible changes to \mh5 from the \mh4 distribution.
+The majority of \mh5 development was in the form of bug fixes and slight
+generalizations.
+In addition, \mh5 is somewhat faster than \mh4:
+all programs have been speeded-up slightly,
+a few, such as \pgm{msh}, have been speeded-up signficantly.
+
+\subsection{Library Paths}
+When a filter or form file argument is given to an \MH/ program,
+and the name specified is not absolute (doesn't start with a \file{/\/}),
+then the \MH/ program will first check in the user's \MH/ directory.
+If the file is not present,
+then program will consult the standard \MH/ library for the file.
+This convention allows the PostMaster to make available system-wide
+templates and skeletons.
+
+\subsection{MH Directory}
+If the \MH/ directory of a user doesn't exist,
+then \MH/ will query the user if it should be created.
+This is primarily useful when copying a \profile/ from one host to another,
+or when the site administrator creates a \profile/ for a user when creating
+the associated login.
+
+\subsection{Documentation}
+Two new documents have been prepared for the \mh5 distribution:
+{\sl The Rand MH Message Handling System: Tutorial},
+which is cited as \cite{MH.TUT};
+and,
+{\sl The Rand MH Message Handling System: The UCI BBoards Facility},
+which is cited as \cite{MH.BB}.
+The former is a useful tutorial for novice users of \MH/.
+The latter describes BBoard handling and \MH/.
+
+\section{Draft Handling}
+This section discusses how the handling of drafts has been changed in \mh5.
+
+The most important change is that the {\it draft-folder} notation
+and the {\it push} option at \whatnow/ level have been explicitly made
+visible in the \MH/ system.
+There's a new profile entry called \eg{Draft-Folder} which defines the
+default draft-folder for the \MH/ user.
+By using this entry, such as \example Draft-Folder:\ +drafts\endexample
+the \MH/ user needn't add \switch{draftfolder\ drafts} to the entries
+for \pgm{comp}, \pgm{dist}, \pgm{forw}, and \pgm{repl} in the user's
+\profile/ file.
+
+\subsection{What Happens if the Draft Exists}
+A new option has been added to \pgm{comp}, \pgm{dist}, \pgm{forw}, and
+\pgm{repl} when the draft already exists: \eg{refile\ +folder}.
+This allows you to \pgm{refile} the draft into another folder and then get a
+fresh draft.
+
+\subsection{Editing Environment}
+In previous versions of \MH/,
+when \pgm{comp}, \pgm{dist}, \pgm{forw}, and \pgm{repl} allowed the user to
+edit the draft,
+the \MH/ user's current working directory was somewhere inside of the user's
+\MH/ directory.
+This often lead to confusing results.
+In \mh5,
+when the user edits a draft,
+the current working directory is unchanged.
+Furthermore, two envariables are defined during the editing session for
+\pgm{dist} and \pgm{forw}:
+\file{\$editalt},
+which is the name of the message (\unix/ file) being distributed or replied-to;
+and,
+\file{\$mhfolder},
+which is the name of the folder (\unix/ directory) containing the message
+being distributed or replied-to.
+
+\subsection{Rapid Composition}
+The \pgm{prompter} command has two new switches \switch{rapid} and
+\switch{norapid}.
+If the \switch{rapid} option is given then \pgm{repl} won't display an
+existing body of the draft being edited.
+This is useful for using \pgm{forw} with a slow terminal.
+
+\subsection{Ultra Rapid Composition}
+The \pgm{comp}, \pgm{dist}, \pgm{forw}, and \pgm{repl} commands have a new
+option, \switch{noedit}.
+If \switch{noedit} is given,
+then the initial edit is supressed.
+This is useful for various canned applications
+(and perhaps more graceful than \switch{-editor /bin/true\/}).
+
+\subsection{Digest Generation}
+The \pgm{forw} command has the beginnings of a digest-composition facility,
+with the \switch{digest\ list}, \switch{issue\ number},
+and \switch{volume\ number} switches.
+
+If \pgm{forw} is given the argument \eg{list} to the \switch{digest} switch,
+and the \switch{issue\ number} switch is not given,
+then \pgm{forw} looks for a profile entry called
+\eg{digest-issue-list:} and increments its value to use as the issue
+number.
+Similarly,
+if the \switch{volume\ number} switch is not given,
+then \pgm{forw} looks for \eg{digest-volume-list:}
+(but does not increment its value) to use as the volume number.
+
+Having calculated the name of the digest and the volume and issue numbers,
+\pgm{forw} will look for a profile entry called \eg{sedproc:}
+(which defaults to \pgm{/bin/sed\/})and filter the components file
+(as specified with the \switch{form\ formfile} switch)
+with the following definitions:
+\eg{@(digest)}, \eg{@(issue)}, \eg{@(volume)}, and \eg{@(date)}.
+
+\tagdiagram{1}{Sample skeleton for digest composition}{digestcomps}
+A good components file to use, (which might be called \file{digestcomps\/}) is
+shown in Figure~\digestcomps.
+
+\pgm{Forw} will now compose the draft,
+using the standard digest encapsulation algorithm
+(even putting a \eg{End of list Digest} trailer in the draft).
+Once the draft is composed by \pgm{forw},
+it writes out the volume and issue profile entries for the digest,
+and then invokes the editor.
+
+\tagdiagram{2}{Sample template for digest messages}{mhldigest}
+Naturally, when composing the draft,
+the \pgm{forw} program will honor the\hbreak
+\switch{filter\ filterfile} switch,
+which is given to \pgm{mhl} to filter each message being forwarded prior to
+encapsulation in the draft.
+A good filter file to use, (which might be called \file{mhl.digest\/})
+is shown in Figure~\mhldigest.
+
+\subsection{Replies}
+The \pgm{repl} command has two new switches \switch{query} and
+\switch{noquery}.
+If the \switch{query} option is given then for each address that would go in
+the \eg{cc:} field of the reply,
+\pgm{repl} asks the user if the address should be included.
+This is sometimes useful for replying to mail sent to a large number of people.
+(Obviously, one could simply edit the draft produced by \pgm{repl},
+but the \switch{query} option is useful if \pgm{prompter} is the editor used
+by \pgm{repl} and one doesn't want to invoke a second editor.)
+
+Previous versions of \pgm{repl} would terminate if a \eg{From:} or
+\eg{Sender:} field was not found or could not be parsed.
+The \pgm{repl} program in \mh5 will continue to compose the reply draft,
+after advising you of this anomaly.
+
+\subsection{Blind Carbon Copies}
+After much experimentation, \MH/ has finally stabilized on the format of
+blind-carbon-copies.
+As in \mh4, when \pgm{post} generates a draft for blind recipients,
+a new draft is composed with a minimal set of headers.
+In \mh5 however, the \eg{BCC-Disclaimer:} field is no longer used.
+Instead, the draft for the blind recipients contains the original message as a
+forwarded message.
+This more clearly identifies a blind-carbon-copy to the blind recipient.
+
+\subsection{File Carbon Copies}
+A message draft can now have more than one folder listed in a \eg{Fcc:} field.
+Each folder should be separated by a comma, just like the addresses in a
+\eg{cc:} field.
+In addition, the folders listed in a \eg{Fcc:} field may use the
+relative-folder addressing notation
+(though this latter activity is not recommended).
+
+\subsection{Refiling the Draft}
+At \whatnow/ level, there is a new option, \eg{refile}.
+This options takes any arguments acceptable to the \pgm{refile} program,
+and \pgm{refile\/}'s the message draft into the named folder(s).
+
+\subsection{Annotations}
+If the \switch{annotate} switch is given to \pgm{dist}, \pgm{forw}, or
+\pgm{repl}, and the message is (re)moved by the user prior to the successful
+posting of the draft, the \MH/ program will not complain as before.
+Hence, users of the \eg{push} option at \whatnow/ level need not worry about
+asynchronous error messages.
+
+\section{Other Changes}
+This last section describes the other more program-specific changes made to
+\MH/.
+
+\subsection{Bursting}
+The bursting mechanism in \MH/ has been made sufficiently general to allow
+\pgm{burst} to work on forwarded messages and blind-carbon-copies in addition
+to digests.
+Although \pgm{burst} can not always successfully decapsulate messages
+encapsulated by sites not running \MH/,
+it handles forwarded messages and blind-carbon-copies,
+as constructed by \pgm{forw} and \pgm{send}, easily.
+
+In addition, the \pgm{send} program has two new switches,
+\switch{forward}, and \switch{noforward}.
+If the \switch{forward} option is given,
+then if a \pgm{send} which has been \pgm{push\/}'d in the background fails,
+in addition to containing the reasons for the failure,
+the failure notice contains the draft as a forwarded message.
+This means one can simply \pgm{burst} the failure notice to get the draft
+back,
+instead of hunting around for it.
+
+\subsection{Incorporation of Mail}
+There's a new profile entry called \eg{MailDrop} which can be used to define
+the default maildrop that \pgm{inc} should use.
+In addition, if the envariable \file{\$MAILDROP} is defined,
+then \pgm{inc} will use its value as the default maildrop.
+
+The \pgm{inc} program also has a new option:
+\switch{truncate} and \switch{notruncate},
+which indicates if the maildrop should be truncated.
+By default, \switch{truncate} is used defualt maildrop is used,
+otherwise \switch{notruncate} is used.
+
+\subsection{Clearing the Display}
+The \switch{ff} and \switch{noff} switches have been removed from the
+\pgm{scan} and \pgm{mhl} programs.
+Instead, the \pgm{scan} has been given two switches,
+\switch{clear} and \switch{noclear}
+(\pgm{mhl} already has these switches).
+The action of the \switch{clear} option is simple:
+if the standard output to the \MH/ program is a terminal,
+then the program will output the correct ``escape sequence'' to clear the
+terminal's screen;
+if the standard output is not a terminal,
+then the program will output a formfeed.
+
+In addition,
+both \pgm{scan} and \pgm{mhl} consult the \file{\$TERM} envariable to
+determine such things as the length and width of your terminal.
+The \pgm{scan} program uses this to determine how long each line of the scan
+listing should be.
+The \pgm{mhl} program uses this to determine the default length and width
+of your terminal (instead of the $40$ by $80\/$),
+prior to reading the template or consulting command line options.
+
+\subsection{Folder Handling}
+If the \pgm{folder} command is given the name of a folder that does not exist,
+\pgm{folder} will query the user if the folder should be created.
+This is useful for creating a folder that the \MH/ user intends to access
+later.
+
+In previous releases of \MH/,
+the \pgm{rmf} program would consider a folder writable if it was writable by
+the user.
+Since \pgm{rmf} ultimately removes the folder itself,
+\pgm{rmf} considers a folder writable if the folder and its parent are
+writable by the user.
+If not, the folder is treated as a read-only folder by \pgm{rmf}.
+
+\subsection{MailDrops}
+The name of the \pgm{pack} program has been changed to \pgm{packf}.
+The author didn't want to do this.
+Some people don't know when to leave well enough alone.
+
+\subsection{Refiling}
+The \pgm{refile} program now has a \switch{draft} switch saying to file the
+current draft.
+
+\subsection{RcvMail Support}
+In addition to the standard \pgm{rcvpack} and \pgm{rcvtty} receive mail hooks,
+and the \pgm{rcvtrip} shell script,
+there's a new rcvmail hook called \pgm{rcvdist}.
+The \pgm{rcvdist} hook allows a user of \MH/ to have his/her mail forwarded
+without the intervention of the PostMaster.
+(By the way, the \pgm{rcvpack} hook used to be called \pgm{rcvcron\/}.)
+
+\subsection{Reading BBoards}
+The \pgm{msh} program (which used to be called \pgm{bbr\/})
+implements an \MH/ shell.
+In addition to the commands that the old \pgm{bbr} program had,
+\pgm{msh} also has the
+\pgm{inc}, \pgm{mhmail}, \pgm{pack}, \pgm{rmm} and \pgm{sortm} commands.
+
+In addition, \pgm{msh} uses a ``maildrop mapping'' mechanism to
+significantly speed-up its start-up time compared to the old \pgm{bbr}.
+The \pgm{pack} program supports this mechanism as well,
+so \pgm{msh} starts quickly on ordinary \pgm{pack\/}'d files as well.
+
+Finally, \pgm{mhl} is now built-in to \pgm{msh},
+so with a \eg{showproc} of \pgm{mhl},
+the \pgm{msh} user gets speedy response in listing messages.

+\begin{abstract}
+This document describes the user-visible change to the
+UCI version of the Rand \MH/ system that were made from \mh5 to \MH/ \#6.5.
+It is based on the \mh6 changes document,
+but has been updated to accurately reflect the \MH/ distributed with
+4.3\bsd/~\unix/.
+This document does not describe bug-fixes, per se,
+or internal changes,
+unless these activities resulted in a visible change for the \MH/ user.
+
+This document is meant to supplement,
+not supersede, the standard \MH/ User's manual\cite{MH.USR}.
+
+Comments concerning this documentation should be addressed to the Internet

+\newpage
+\section*     {Acknowledgements}
+The \MH/ system described herein is based on the original Rand \MH/ system.
+It has been extensively developed (perhaps too much so) by Marshall T.~Rose
+and John L.~Romine at the University of California, Irvine.
+Einar A.~Stefferud, Jerry N.~Sweet,
+and Terry P.~Domae provided numerous suggestions
+to improve the UCI version of \MH/.
+Of course,
+a large number of people have helped \MH/ along.
+The list of ``\MH/~immortals'' is too long to list here.
+However, Van Jacobson deserves a special acknowledgement for his tireless
+work in improving the performance of \MH/.
+Some programs have been speeded-up by a factor of 10 or 20.
+All of users of \MH/, everywhere, owe a special thanks to Van.
+
+\section*     {Disclaimer}
+The Regents of the University of California wish to make it known that:

+\section*     {Conventions}
+In this document,
+certain \LaTeX -formatting conventions are adhered to:
+\begin{enumerate}
+\item  The names of \unix/ commands, such as \pgm{comp},
+are presented in {\it text italics}.
+
+\item  Arguments to programs, such as \arg"msgs",
+are presented in {\tt typewriter style} and delimited by single-quotes.
+
+\item  \unix/ pathnames and envariables,
+such as $$\file{/usr/uci/}\hbox{\qquad and\qquad}\file{\$SIGNATURE},$$
+are presented in {\sl slanted roman}.

+\end{enumerate}
+
+\newpage
+\section*     {General Changes}
+Unlike the changes between \mh4 and \mh5,
+a large number of user-visible changes have been made in \mh6.
+These changes have been in the form of bug fixes and several generalizations.
+The majority of these will not affect novice users.
+In addition, \mh6 is a great deal faster than \mh5:
+all programs have been speeded-up significantly,
+thanks to work done by Van Jacobson as part of the process of including \mh6
+in the 4.3\bsd/~\unix/ distribution.
+
+This document describes all user-visible changes to \mh5 from it's initial
+release to the intermediate release of \MH/ \#6.5.
+
+\subsection*   {System-5 Support}
+In addition to support for \bsd/~\unix/, V7~\unix/ and \xenix/ variants of
+\unix/,
+\MH/ finally has support for the AT\&T variant of \unix/, System~5.
+Hopefully this will greatly expand the number of system which can run \MH/.
+Ironically,
+it appears that five ports of earlier versions of \MH/ (including \mh5)
+were done,
+but news of the work was not widespread.%
+\footnote{In fact,
+three groups in one large organization ported \MH/ independently,
+each without knowledge of the others' work.}
+
+\subsection*   {Documentation}
+Several new documents have been included in the \mh6 distribution:
+The paper {\em MH.5: How to process 200 messages a day and still get some
+real work done}
+was presented at the 1985 Summer Usenix Conference and Exhibition in
+Portland, Orgeon.
+Another paper, {\em MH: A Multifarious User Agent},
+has been accepted for publication by Computer Networks.
+Both describe \MH/,
+the former from a more technical and somewhat humorous perspective,
+the latter from a more serious and research-oriented perspective.
+In addition,
+a third paper has been included,
+{\em Design of the TTI Prototype Trusted Mail Agent},
+which describes a so-called ``trusted'' mail agent built on top of \MH/.
+This paper was presented at the Second International Symposium on
+Computer Message Systems in Washington, D.C.
+A fourth paper,
+{\em MZnet: Mail Service for Personal Micro-Computer Systems},
+is also included.
+This paper,
+which was presented at the First International Symposium on Computer Message
+Systems in Nottingham, U.K.,
+describes a \cpm/-based version of \MH/.
+
+In addition,
+the \MH/ tutorial, {\em The Rand MH Message Handling System: Tutorial},
+and,
+{\em The Rand MH Message Handling System: The UCI BBoards Facility},
+have both been updated by Jerry N.~Sweet.
+
+For \MH/ administrators (PostMasters and the like),
+there's an entirely new document,
+{\em The Rand MH Message Handling System: Administrator's Guide}.
+It explains most of the ``ins and outs'' of maintaining an \MH/ system.
+
+Finally, all of the manual entries and the \MH/ manual have had a thorough
+working over.
+The documentation is expanded, more accurate, and more detailed.
+
+\subsection*   {Help Listings}
+When any \MH/ command is invoked with the \switch"help" switch,
+in addition to listing the syntax of the command and version information,
+the \MH/ configuration options will be listed.
+\MH/ has so many configuration options,
+that when debugging problems, this information is invaluable.
+
+\subsection*   {The \MH/ Profile}
+There are two new profile entries worth noting:
+\verb"MH-Sequences" tells \MH/ the name of the file to record public
+sequences in.
+Users of \pgm{vm}, a proprietary, visual front-end to \MH/,
+make use of this to disable the public sequences feature of \MH/.
+
+The profile entry \verb"Unseen-Sequence" names those sequences which should be
+defined as those messages recently incorporated by \pgm{inc}.
+The \pgm{show} program knows to remove messages from this sequence once it
+thinks they have been seen.
+If this profile entry is not present, or is empty, then no sequences are
+defined.
+Otherwise, for each name given, the sequence is first zero'd and then each
+message incorporated is added to the sequence.
+As such, this profile entry is rather analogous to the
+\verb"Previous-Sequence" entry in the user's \MH/ profile.
+
+In addition, the \verb"Alternate-Mailboxes" entry in the profile has been
+expanded to support simple wild-carding.
+Also, the default for this profile entry is now the user's mail-id at any host.
+This change was made since \MH/ can no longer reliably figure out what
+the user's real outgoing address looks like.
+
+Finally,
+when the \pgm{install-mh} program is automatically invoked by \MH/,
+it won't prompt the user for information.
+Instead, it notes that it's setting up the default environment.
+In addition,
+the \MH/ administrator may set-up a file called \file{mh.profile} in the \MH/
+library area which is consulted by \pgm{install-mh} when initializing the
+user's \profile/.
+
+\subsection*   {The \MH/ Context}
+The \pgm{folder}, \pgm{scan}, and \pgm{show} programs have been modified to
+update the user's \MH/ context prior to writing to the user's terminal.
+This allows the \MH/ user interrupt output to the terminal and still have the
+expected context.
+This is especially useful to interrupt long \pgm{scan} listings.
+This change also introduces a subtle bug between \pgm{show} and messages
+denoted by the \verb"Unseen-Sequence".
+See \man show(1) for the details.
+
+\subsection*   {Addresses and 822 support}
+\MH/ now fully supports the RFC-822 routing syntax for addresses
+(it used to recognize the syntax, but ignore the information present).
+In addition,
+there are three major modes for support of non-822 addressing in \MH/:
+\begin{itemize}
+\item  BERK\\
+This is useful on sites running \SendMail/.
+It doesn't support full 822--style addressing,
+in favor of recognizing such formats as ACSnet, and so on.
+For sites that can't run in an 822--compliant environment,
+this is the option to use
+(at the price of sacrificing some of the power of 822--style addressing).
+This also drastically reduces the address formatting facilities described
+below.
+
+\item  DUMB\\
+Although not as liberal as BERK,
+the DUMB option is useful on sites in which the message transport system
+conforms to the 822 standard,
+but wants to do all the defaulting itself.
+
+\item  BANG\\
+From out in left field,
+the BANG option favors \UUCP/-style addressing over 822--style addressing.
+Hopefully when all the \UUCP/ sites around get around to adopting domain-style
+addresses, this option won't be needed.
+\end{itemize}
+
+The \pgm{ap} program (mentioned momentarily) and the \pgm{ali} program
+both support a \switch"normalize" switch indicate if addresses should be
+resolved to their ``official'' hostnames.
+
+\subsection*   {New Programs}
+There are five new programs available:
+The \pgm{ap} program is the \MH/ stand-alone address parser.
+It's useful for printing address in various formats
+(and for debugging address strings).
+The \pgm{dp} program is similar, but works on dates instead of addresses.
+
+The \pgm{msgchk} program checks for new mail,
+possibly using the Post Office Protocol, POP, described below.
+
+A new receive mail hook,
+the \pgm{rcvstore} program,
+which was written by Julian L.~Onions is available.
+
+Finally, a visual front-end to \pgm{msh} called \pgm{vmh} has been included.
+(This program is discussed in greater detail later on.)
+
+\subsection*   {Message Numbering}
+\MH/ now no longer restricts the number of messages which may reside in a
+folder
+(beyond that of system memory constraints).
+This means that message numbers larger than 2000 are permissible.
+Hopefully this will make life easier for people reading the network news
+using \MH/.
+
+\section*     {The WhatNow Shell}
+In \mh6,
+there is now the concept of a unified \whatnow/ processor that
+the four composition programs, \pgm{comp}, \pgm{dist}, \pgm{forw},
+and \pgm{repl} all invoke.
+This permits a greater flexibility in building mail applications with \MH/.
+As a result, there's a new program, \pgm{whatnow}, which acts as the default
+\whatnow/ program.
+Consult the \man whatnow(1) manual entry for all the details.
+The only important user-visible change is the \verb"headers" option went away,
+which wasn't used that much anyway.
+
+
+The only other thing worth noting is that unless \MH/ has been compiled with
+the UCI option,
+the user's \file{\$HOME/.signature} file is not consulted for the user's
+personal name.
+
+\section*     {Format Strings}
+A general format string facility has been added to allow \MH/ users to tailor
+the output of certain commands.
+
+The \pgm{inc}, \pgm{scan}, \pgm{ap}, and \pgm{dp} programs all consult a
+file containing format strings.
+Format strings,
+which look a lot like \man printf(3) strings,
+give these \MH/ commands precise instructions on how to format their output.
+
+As a result,
+the \pgm{inc} and \pgm{scan} programs no longer have the
+\switch"size", \switch"nosize",
+\switch"time", \switch"notime",
+\switch"numdate", and \switch"nonumdate"
+switches.
+These switches have been replaced with the
+\switch"form formatfile" switch and the \switch"format string" switch.
+The former directs the program to consult the named file for the format
+strings.
+The latter directs the program to use the named string as the format.
+To get the behavior of the old \switch"time" option,
+use the \switch"form scan.time" option.
+Similarly,
+to get the effect of \switch"size",
+use \switch"form scan.size".
+
+A fun form to use is \switch"form scan.timely" with \pgm{scan}.
+Try it sometime.
+
+
+The \pgm{repl} command uses a file containing format files to
+indicate how the reply draft should be constructed.
+Note that reply templates prior to \mh6 are incompatible with \mh5.%
+\footnote{In fact, reply templates between \mh6 and \MH/ \#6.5 are
+imcompatible.}
+Don't worry though,
+it's quite easy to convert the templates by hand.
+(Those clever enough to have written a reply template to begin with won't
+have {\em any\/} problem.)
+
+Similarly, when the \pgm{forw} program is constructing a digest,
+it uses a file containing format strings to indicate how to build the
+encapsulating draft.
+
+Finally, you can use these facilities in \pgm{mhl} as well.
+
+\section*     {News}
+The depreciated \MH/ news system (from \mh1) is now de-supported.
+Use the ``hoopy'' BBoards facility instead.
+
+\section*     {BBoards}
+\MH/ maintainers take note:
+the default home directory for the bboards login has changed from
+\file{/usr/bboards/} to \file{/usr/spool/bboards/}.
+Use the \verb"bbhome" directive in your \MH/ configuration file to set
+it back to the old value if you wish.
+
+In addition, the aliases field for a BBoard in the BBoards file is now
+deemed useful only for addressing, not for user input to \pgm{bbc}.
+This means when giving the name of a BBoard to \pgm{bbc},
+only the official name should be used.
+
+A final note for mailsystem maintainers:
+the \MMDFII/ BBoards channel and the \SendMail/ BBoards mailer have been
+modified to use the standard message encapsulation format when returning
+failed messages to the list maintainer.
+This means that the failure notices that the maintainer receives can
+simply be \pgm{burst}.
+
+\subsection*   {New Switches in bbc}
+The \pgm{bbc} program permits you to specify the \verb"mshproc" to use on the
+command line by using the \switch"mshproc program" option.
+There's also a \switch"rcfile file" option which does ``the obvious thing''.
+In addition, options which aren't understood by \pgm{bbc} are passed along to
+the \verb"mshproc".
+
+In addition, the following commands
+pass any unrecognized switches on to the program that they invoke:
+\pgm{bbc}, \pgm{next}, \pgm{show}, \pgm{prev}, and \pgm{vmh}.
+
+\subsection*   {Distributed BBoards}
+If both BBoards and POP (see the next section) are enabled,
+then distributed BBoards can be supported on top of the POP service.
+This allows the \MH/ user to read BBoards on a server machine
+instead of the local host
+(which saves a lot of wasted disk space when the same BBoards are replicated
+several times at a site with several hosts).
+See the {\em Administrator's Guide\/} for information on how this can be made
+completely transparent to the \MH/ user.
+
+If you have several machines at your site running 4.2\bsd/~\unix/
+and connected by an \ethernet/ (or other high-speed LAN),
+you {\em want\/} this software.
+
+\subsection*   {Visual Front-End to msh}
+A simple window management protocol has been implemented for \MH/ programs
+that might wish to act as a back-end to a sophisticated visual front-end.
+
+The first implementation of a server side (front-end) program is \pgm{vmh},
+which uses \man curses(3) to maintain a split-screen interface.
+Perhaps look for a \pgm{mhtool} program for the SUN next!
+
+The \pgm{msh} program has been modified to speak the client side (back-end)
+of this protocol, if so directed.
+At present, \pgm{msh} is the only program in the \MH/ distribution which
+implements the client side of the window management protocol.
+
+\subsection*   {Updates in msh}
+Prior to quitting,
+the \pgm{msh} command now asks if the \pgm{packf\/}'d file you've been
+perusing should be updated if you've modified it and the file is writable by
+you.
+The file can be modified by using \pgm{burst}, \pgm{rmm}, \pgm{rmm},
+or \pgm{sortm} commands.
+The file can also be modified by using the \pgm{refile} command without the
+\switch"link" option.
+(Or course,
+the \switch"link" option doesn't actually link anything to the file.)
+
+\section*     {Distributed Mail}
+\MH/ now contains a powerful facility for doing distributed mail
+(having \MH/ reside on a host different than the message transport agent).
+For general information,
+consult either the 
+{\em MH.5: How to process 200 messages a day and still get some real work
+done} paper,
+or the {\em MH: A Multifarious User Agent} paper.
+For specific information,
+consult the {\em Administrator's Guide}.
+Here's a brief synopsis:
+
+This POP facility in \MH/ is based on a modification of the ARPA Post
+Office Protocol (POP).
+A POP {\em subscriber\/} is a remote user,
+on a POP {\em client host},
+that wishes to pick-up mail on a POP {\em service host}.
+
+There are two ways to administer POP:
+\begin{itemize}
+\item  Naive Mode\\
+Each user-id in the \man passwd(5) file is considered a POP subscriber.
+No changes are required for the mailsystem on the POP service host.
+However,
+this method requires that each POP subscriber have an entry in the password
+file.
+The POP server will fetch the user's mail from wherever maildrops are kept on
+the POP service host.
+This means that if maildrops are kept in the user's home directory,
+then each POP subscriber must have a home directory.
+
+\item  Smart Mode\\
+This is based on the notion that the list of POP subscribers and the list of
+login users are completely separate name spaces.
+A separate database (similar to the \man BBoards(5) file)
+is used to record information about each POP subscriber.
+Unfortunately,
+the local mailsystem must be changed to reflect this.
+This requires two changes (both of which are simple):
+\begin{enumerate}
+\item  Aliasing\\
+       The aliasing mechanism is augmented so that POP subscriber addresses
+       are diverted to a special delivery mechanism.
+       \MH/ comes with a program, \man popaka(8), which generates the
+       additional information to be put in the mailsystem's alias file.
+\item  Delivery\\
+       A special POP delivery channel (for \MMDFII/)
+       or POP mailer (for \SendMail/) performs the actual delivery (\mh6
+       supplies both).
+       All it really does is just place the mail in the POP spool area.
+\end{enumerate}
+Clever mailsystem people will note that
+the POP mechanism is really a special case of the more general
+BBoards mechanism.
+\end{itemize}
+These two different philosophies are not compatible on the same POP service
+host: one or the other, but not both, may be run.
+
+In addition, there is one user-visible difference,
+which the administrator controls the availability of.
+The difference is whether the POP subscriber must supply a password to the POP
+server:
+\begin{itemize}
+\item  ARPA standard method\\
+This uses the standard ARPA technique of sending a username and a password.
+The appropriate programs (\pgm{inc}, \pgm{msgchk}, and possibly \pgm{bbc\/})
+will prompt the user for this information.
+
+\item  \unix/ remote method\\
+This uses the Berkeley \unix/ reserved port method for authentication.
+This requires that the two or three mentioned above programs be {\em setuid\/}
+to root.
+(There are no known holes in any of these programs.)
+\end{itemize}
+These two different philosophies are compatible on the same POP service host:
+to selectively disable RPOP for hosts which aren't trusted,
+either modify the \file{.rhosts} file in the case of POP subscribers being
+\unix/ logins,
+or zero the contents of network address field of the \man pop(5) file for the
+desired POP subscribers.
+
+The \pgm{inc} command also has two other switches when \MH/ is enabled for
+POP:
+\switch"pack file" and \switch"nopack".
+Normally,
+\pgm{inc} will use the POP to incorporate mail from a POP service host into
+an \MH/ folder (\verb"+inbox").
+However,
+there are some misguided individuals who prefer to \pgm{msh} to read their
+maildrop.
+By using the \switch"pack file" option,
+these individuals can direct \pgm{inc} to fetch their maildrop from the POP
+service host and store it locally in the named file.
+As expected, \pgm{inc} will treat the local file as a maildrop,
+performing the appropriate locking protocols.
+And,
+if the file doesn't exist,
+the user is now asked for confirmation.
+
+\section*     {Rcvmail hooks}
+In order to offer users of \MH/ increased rcvmail hook functionality,
+the \pgm{slocal} program has been upgraded to support the semantics of
+the \MMDFII/ mail-delivery mechanism.
+This means that users of \mh6 can maintain identical \file{.maildelivery}
+files regardless of the underlying transport system.
+See \man mhook(1) for all the details.
+
+\subsection*   {Change in rcvdist}
+The \pgm{rcvdist} rcvmail hook now uses the \MH/ formatting facility when
+redistributing a message.
+
+\subsection*   {Field change in rcvpack}
+The \pgm{rcvpack} rcvmail hook now adds the field name \verb"Delivery-Date:"
+instead of \verb"Cron-Date:" to messages it \pgm{pack\/}s.
+
+\section*     {GNU Emacs Support}
+James Larus' \pgm{mh-e} macro package for GNU Emacs (version~17) is included
+in the distribution.
+When loaded in Emacs, this provides a handy front-end.
+
+\section*     {Other Changes}
+Here's the miscellany:
+
+\subsection*   {Continuation Lines}
+Alias files used by \MH/,
+display templates used by \pgm{mhl},
+and format files used by \pgm{forw}, \pgm{repl}, and \pgm{scan} all support
+a standard continuation line syntax.
+To continue a line in one of these files,
+simply end the line with the backslash character (`$\backslash$').
+All the other files used by \MH/ are in 822--format,
+so the 822--continuation mechanism is used.%
+\footnote{Looking back,
+it would have been best had all files in \MH/ used the 822--format.}
+
+\subsection*   {Default Date Format}
+\MH/ now uses numeric timezones instead of locally-meaningful alpha timezones
+when generating mail.
+This change was made to encourage the use of unambiguous, globally-meaningful
+timezone strings.
+A local configuration option can disable this correct behavior.
+All of the \pgm{mhl} templates have been modified to use locally-meaningful
+alpha timezones when displaying messages.
+
+\subsection*   {New switch in ali}
+The \pgm{ali} command now has a \switch"noalias" switch to prevent
+system-wide aliases from being interpreted.
+
+\subsection*   {Modifications to show}
+The \switch"format", \switch"noformat", \switch"pr", and \switch"nopr"
+options to \pgm{show} have gone away in favor of a more general mechanism.
+The \switch"showproc program" option tells \pgm{show}
+(or \pgm{next} or \pgm{prev\/}) to use the named program as the 
\verb"showproc".
+The \switch"noshowproc" option tells \pgm{show}, et. al.,
+to use the \man cat(1) program instead of a \verb"showproc".
+As a result, the profile entry \verb"prproc" is no longer used.
+
+\subsection*   {Switch change in inc}
+The \switch"ms ms-file" switch in \pgm{inc} has been changed to
+\switch"file name" to be more consistent.
+
+\subsection*   {Front-End to mhl}
+When outputting to a terminal,
+the \pgm{mhl} program now runs the program denoted by the profile entry
+\verb"moreproc".
+If this entry is not present,
+the default is the UCB \pgm{more} program.
+If the entry is non-empty,
+then that program is spliced between \pgm{mhl} and the user's terminal.
+The author uses the \pgm{less} program as his \verb"moreproc".
+
+Of course,
+if \pgm{mhl} isn't outputting to a terminal,
+then \verb"moreproc" is not invoked.
+
+Finally,
+to aid in the construction of replies,
+a prefix string may be specified for the \verb"body" component of the message
+being replied-to.
+Simply use the \verb"component=" construct in \pgm{mhl} for \verb"body:".
+
+\subsection*   {Confirmation in packf}
+If the file specified by the \switch"file name" switch doesn't exist,
+the user is now asked for confirmation.
+
+\subsection*   {Complex Expressions in pick}
+The \pgm{pick} command now handles complex boolean expressions.
+
+\subsection*   {Defaults change in prompter and burst}
+The \switch"prepend" option is now the default in \pgm{prompter}.
+The \switch"noinplace" option is now the default in \pgm{burst}.
+
+\subsection*   {Fcc:s and post}
+If multiple Fcc:s for a message are specified during posting,
+\pgm{post} will try much harder to preserve links.
+
+\subsection*   {Interactive option in rmf}
+The \pgm{rmf} program has been changed to support an \switch"interactive"
+switch.
+If given,
+then the user is prompted regarding whether the folder should be deleted.
+If the folder to be removed is not given by the user,
+this switch is defaulted to on.
+
+\subsection*   {Trusted Mail Interface}
+\MH/ now has an interface for so-called ``trusted mail'' applications.
+Although the modifications to \MH/ to support this are in the public domain,
+the actual library that \MH/ uses is not.
+Contact Professor David J.~Farber ({\sf address@hidden/}) for more information.

+
+       uip/{ap,dp,{repl,scan}sbr}.c: the old echo controversy raises it's
+           ugly head: suppose we have a line in a replcomps file which is
+           entirely in a %<...%> conditional and the conditional is false.
+           In that case, we still get a blank line.  This is very BAD if it
+           occurs in the headers.  Two solutions possible:
+               1. If a call to FSprintf() returns a empty string, don't
+                  put out a \n.
+               2. In new_fs, put the \n's in and just return one big
+                  string instead of an array of strings.
+           Option [2] was implemented initially because it lets conditionals
+           span multiple lines in the file.  In order to keep the format files
+           from looking too complicated, EOL was ignored in format files,
+           \n's should be embedded where appropriate.  A single format
+           string argument is considered to have an implicit \n.  This is
+           inconsistent, but it keeps the format files readable.  Option [2]
+           was discarded though since it required a \n at the end of each
+           line in the format file if there was no conditional stuff
+           there.  So, option [1] got implemented even though it doesn't
+           allow conditionals to be multi-line (which is okay, since you
+           can use \n in a line).

+\section*     {Acknowledgements}
+The \MH/ system described herein is based on the original Rand \MH/ system.
+It has been extensively developed (perhaps too much so) by Marshall T.~Rose
+and John L.~Romine at the University of California, Irvine.
+Einar A.~Stefferud, Jerry N.~Sweet,
+and Terry P.~Domae provided numerous suggestions
+to improve the UCI version of \MH/.
+Of course,
+a large number of people have helped \MH/ along.
+The list of ``\MH/~immortals'' is too long to list here.
+

+
+\section*     {General Changes}
+Unlike the changes between \mh4 and \mh5,
+a large number of user-visible changes have been made in \mh6.
+These changes have been in the form of bug fixes and several generalizations.
+The majority of these will not affect novice users.
+In addition, \mh6 is a great deal faster than \mh5:
+all programs have been speeded-up significantly,
+thanks to work done by Van Jacobson as part of the process of including \mh5
+in the 4.3\bsd/~\unix/ distribution.
+
+This document describes all user-visible changes to \mh5 from it's initial
+release to the initial release of \mh6.
+
+\subsection*   {System-5 Support}
+In addition to support for \bsd/~\unix/, V7~\unix/ and \xenix/ variants of
+\unix/,
+\MH/ finally has support for the AT\&T variant of \unix/, System~5.
+Hopefully this will greatly expand the number of system which can run \MH/.
+Ironically,
+it appears that five ports of earlier versions of \MH/ (including \mh5)
+were done,
+but news of the work was not widespread.%
+\nfootnote{In fact,
+three groups in one large organization ported \MH/ independently,
+each without knowledge of the others' work.}
+
+\subsection*   {Documentation}
+Several new documents have been included in the \mh6 distribution:
+The paper {\em MH.5: How to process 200 messages a day and still get some
+real work done}
+was presented at the 1985 Summer Usenix Conference and Exhibition in
+Portland, Orgeon.
+Another paper, {\em MH: A Multifarious User Agent},
+has been accepted for publication by Computer Networks.
+Both describe \MH/,
+the former from a more technical and somewhat humorous perspective,
+the latter from a more serious and research-oriented perspective.
+In addition,
+a third paper has been included,
+{\em Design of the TTI Prototype Trusted Mail Agent},
+which describes a so-called ``trusted'' mail agent built on top of \MH/.
+This paper was presented at the Second International Symposium on
+Computer Message Systems in Washington, D.C.
+A fourth paper,
+{\em MZnet: Mail Service for Personal Micro-Computer Systems},
+is also included.
+This paper,
+which was presented at the First International Symposium on Computer Message
+Systems in Nottingham, U.K.,
+describes a \cpm/-based version of \MH/.
+
+In addition,
+the \MH/ tutorial, {\em The Rand MH Message Handling System: Tutorial},
+and,
+{\em The Rand MH Message Handling System: The UCI BBoards Facility},
+have both been updated by Jerry N.~Sweet.
+
+For \MH/ administrators (PostMasters and the like),
+there's an entirely new document,
+{\em The Rand MH Message Handling System: Administrator's Guide}.
+It explains most of the ``ins and outs'' of maintaining an \MH/ system.
+
+Finally, all of the manual entries and the \MH/ manual have had a thorough
+working over.
+The documentation is expanded, more accurate, and more detailed.
+
+\subsection*   {Help Listings}
+When any \MH/ command is invoked with the \switch{help} switch,
+in addition to listing the syntax of the command and version information,
+the \MH/ configuration options will be listed.
+\MH/ has so many configuration options,
+that when debugging problems, this information is invaluable.
+
+\subsection*   {The \MH/ Profile}
+There are two new profile entries worth noting:
+\eg{MH-Sequences} tells \MH/ the name of the file to record public
+sequences in.
+Users of \pgm{vm}, a proprietary, visual front-end to \MH/,
+make use of this to disable the public sequences feature of \MH/.
+
+The profile entry \eg{Unseen-Sequence} names those sequences which should be
+defined as those messages recently incorporated by \pgm{inc}.
+The \pgm{show} program knows to remove messages from this sequence once it
+thinks they have been seen.
+If this profile entry is not present, or is empty, then no sequences are
+defined.
+Otherwise, for each name given, the sequence is first zero'd and then each
+message incorporated is added to the sequence.
+As such, this profile entry is rather analogous to the
+\eg{Previous-Sequence} entry in the user's \MH/ profile.
+
+In addition, the \eg{Alternate-Mailboxes} entry in the profile has been
+expanded to support simple wild-carding.
+Also, the default for this profile entry is now the user's mail-id at any host.
+This change was made since \MH/ can no longer reliably figure out what
+the user's real outgoing address looks like.
+
+Finally,
+when the \pgm{install-mh} program is automatically invoked by \MH/,
+it won't prompt the user for information.
+Instead, it notes that it's setting up the default environment.
+In addition,
+the \MH/ administrator may set-up a file called \file{mh.profile} in the \MH/
+library area which is consulted by \pgm{install-mh} when initializing the
+user's \profile/.
+
+\subsection*   {The \MH/ Context}
+The \pgm{folder}, \pgm{scan}, and \pgm{show} programs have been modified to
+update the user's \MH/ context prior to writing to the user's terminal.
+This allows the \MH/ user interrupt output to the terminal and still have the
+expected context.
+This is especially useful to interrupt long \pgm{scan} listings.
+This change also introduces a subtle bug between \pgm{show} and messages
+denoted by the \eg{Unseen-Sequence}.
+See \man show(1) for the details.
+
+\subsection*   {Addresses and 822 support}
+\MH/ now fully supports the RFC-822 routing syntax for addresses
+(it used to recognize the syntax, but ignore the information present).
+In addition,
+there are three major modes for support of non-822 addressing in \MH/:
+\begin{itemize}
+\item  BERK\hbreak
+This is useful on sites running \SendMail/.
+It doesn't support full 822--style addressing,
+in favor of recognizing such formats as ACSnet, and so on.
+For sites that can't run in an 822--compliant environment,
+this is the option to use
+(at the price of sacrificing some of the power of 822--style addressing).
+
+\item  DUMB\hbreak
+Although not as liberal as BERK,
+the DUMB option is useful on sites in which the message transport system
+conforms to the 822 standard,
+but wants to do all the defaulting itself.
+
+\item  BANG\hbreak
+From out in left field,
+the BANG option favors \UUCP/-style addressing over 822--style addressing.
+Hopefully when all the \UUCP/ sites around get around to adopting domain-style
+addresses, this option won't be needed.
+\end{itemize}
+
+The \pgm{ap} program (mentioned momentarily) and the \pgm{ali} program
+both support a \switch{normalize} switch indicate if addresses should be
+resolved to their ``official'' hostnames.
+
+\subsection*   {New Programs}
+There are five new programs available:
+The \pgm{ap} program is the \MH/ stand-alone address parser.
+It's useful for printing address in various formats
+(and for debugging address strings).
+The \pgm{dp} program is similar, but works on dates instead of addresses.
+
+The \pgm{msgchk} program checks for new mail,
+possibly using the Post Office Protocol, POP, described below.
+
+A new receive mail hook,
+the \pgm{rcvstore} program,
+which was written by Julian L.~Onions is available.
+
+Finally, a visual front-end to \pgm{msh} called \pgm{vmh} has been included.
+(This program is discussed in greater detail later on.)
+
+\subsection*   {Message Numbering}
+\MH/ now no longer restricts the number of messages which may reside in a
+folder
+(beyond that of system memory constraints).
+This means that message numbers larger than 2000 are permissible.
+Hopefully this will make life easier for people reading the network news
+using \MH/.
+
+\section*     {The WhatNow Shell}
+In \mh6,
+there is now the concept of a unified \whatnow/ processor that
+the four composition programs, \pgm{comp}, \pgm{dist}, \pgm{forw},
+and \pgm{repl} all invoke.
+This permits a greater flexibility in building mail applications with \MH/.
+As a result, there's a new program, \pgm{whatnow}, which acts as the default
+\whatnow/ program.
+Consult the \man whatnow(1) manual entry for all the details.
+
+The only other thing worth noting is that unless \MH/ has been compiled with
+the UCI option,
+the user's \file{\$HOME/.signature} file is not consulted for the user's
+personal name.
+
+\section*     {Format Strings}
+A general format string facility has been added to allow \MH/ users to tailor
+the output of certain commands.
+
+The \pgm{inc}, \pgm{scan}, \pgm{ap}, and \pgm{dp} programs all consult a
+file containing format strings.
+Format strings,
+which look a lot like \man printf(3) strings,
+give these \MH/ commands precise instructions on how to format their output.
+
+As a result,
+the \pgm{inc} and \pgm{scan} programs no longer have the
+\switch{size}, \switch{nosize},
+\switch{time}, \switch{notime},
+\switch{numdate}, and \switch{nonumdate}
+switches.
+These switches have been replaced with the
+\switch{form~formatfile} switch and the \switch{format~string} switch.
+The former directs the program to consult the named file for the format
+strings.
+The latter directs the program to use the named string as the format.
+To get the behavior of the old \switch{time} option,
+use the \switch{form~scan.time} option.
+Similarly,
+to get the effect of \switch{size},
+use \switch{form~scan.size}.
+
+The \pgm{repl} command uses a file containing format files to
+indicate how the reply draft should be constructed.
+Note that reply templates prior to \mh6 are incompatible with \mh5.
+Don't worry though,
+it's quite easy to convert the templates by hand.
+(Those clever enough to have written a reply template to begin with won't
+have {\em any\/} problem.)
+
+Similarly, when the \pgm{forw} program is constructing a digest,
+it uses a file containing format strings to indicate how to build the
+encapsulating draft.
+
+\section*     {News}
+The depreciated \MH/ news system (from \mh1) is now de-supported.
+Use the ``hoopy'' BBoards facility instead.
+
+\section*     {BBoards}
+\MH/ maintainers take note:
+the default home directory for the bboards login has changed from
+\file{/usr/bboards/} to \file{/usr/spool/bboards/}.
+Use the \eg{bbhome} directive in your \MH/ configuration file to set
+it back to the old value if you wish.
+
+In addition, the aliases field for a BBoard in the BBoards file is now
+deemed useful only for addressing, not for user input to \pgm{bbc}.
+This means when giving the name of a BBoard to \pgm{bbc},
+only the official name should be used.
+
+A final note for mailsystem maintainers:
+the \MMDFII/ BBoards channel and the \SendMail/ BBoards mailer have been
+modified to use the standard message encapsulation format when returning
+failed messages to the list maintainer.
+This means that the failure notices that the maintainer receives can
+simply be \pgm{burst}.
+
+\subsection*   {New Switches in bbc}
+The \pgm{bbc} program permits you to specify the \eg{mshproc} to use on the
+command line by using the \switch{mshproc~program} option.
+In addition, options which aren't understood by \pgm{bbc} are passed along to
+the \eg{mshproc}.
+
+In addition, the following commands
+pass any unrecognized switches on to the program that they invoke:
+\pgm{bbc}, \pgm{next}, \pgm{show}, \pgm{prev}, and \pgm{vmh}.
+
+\subsection*   {Distributed BBoards}
+If both BBoards and POP (see the next section) are enabled,
+then distributed BBoards can be supported on top of the POP service.
+This allows the \MH/ user to read BBoards on a server machine
+instead of the local host
+(which saves a lot of wasted disk space when the same BBoards are replicated
+several times at a site with several hosts).
+See the {\em Administrator's Guide\/} for information on how this can be made
+completely transparent to the \MH/ user.
+
+If you have several machines at your site running 4.2\bsd/~\unix/
+and connected by an \ethernet/ (or other high-speed LAN),
+you {\em want\/} this software.
+
+\subsection*   {Visual Front-End to msh}
+A simple window management protocol has been implemented for \MH/ programs
+that might wish to act as a back-end to a sophisticated visual front-end.
+
+The first implementation of a server side (front-end) program is \pgm{vmh},
+which uses \man curses(3) to maintain a split-screen interface.
+Perhaps look for a \pgm{mhtool} program for the SUN next!
+
+The \pgm{msh} program has been modified to speak the client side (back-end)
+of this protocol, if so directed.
+At present, \pgm{msh} is the only program in the \MH/ distribution which
+implements the client side of the window management protocol.
+
+\subsection*   {Updates in msh}
+Prior to quitting,
+the \pgm{msh} command now asks if the \pgm{packf\/}'d file you've been
+perusing should be updated if you've modified it and the file is writable by
+you.
+The file can be modified by using \pgm{burst}, \pgm{rmm}, \pgm{rmm},
+or \pgm{sortm} commands.
+The file can also be modified by using the \pgm{refile} command without the
+\switch{link} option.
+(Or course,
+the \switch{link} option doesn't actually link anything to the file.)
+
+\section*     {Distributed Mail}
+\MH/ now contains a powerful facility for doing distributed mail
+(having \MH/ reside on a host different than the message transport agent).
+For general information,
+consult either the 
+{\em MH.5: How to process 200 messages a day and still get some real work
+done} paper,
+or the {\em MH: A Multifarious User Agent} paper.
+For specific information,
+consult the {\em Administrator's Guide}.
+Here's a brief synopsis:
+
+This POP facility in \MH/ is based on a modification of the ARPA Post
+Office Protocol (POP).
+A POP {\em subscriber\/} is a remote user,
+on a POP {\em client host},
+that wishes to pick-up mail on a POP {\em service host}.
+
+There are two ways to administer POP:
+\begin{itemize}
+\item  Naive Mode\hbreak
+Each user-id in the \man passwd(5) file is considered a POP subscriber.
+No changes are required for the mailsystem on the POP service host.
+However,
+this method requires that each POP subscriber have an entry in the password
+file.
+The POP server will fetch the user's mail from wherever maildrops are kept on
+the POP service host.
+This means that if maildrops are kept in the user's home directory,
+then each POP subscriber must have a home directory.
+
+\item  Smart Mode\hbreak
+This is based on the notion that the list of POP subscribers and the list of
+login users are completely separate name spaces.
+A separate database (similar to the \man BBoards(5) file)
+is used to record information about each POP subscriber.
+Unfortunately,
+the local mailsystem must be changed to reflect this.
+This requires two changes (both of which are simple):
+\begin{enumerate}
+\item  Aliasing\hbreak
+       The aliasing mechanism is augmented so that POP subscriber addresses
+       are diverted to a special delivery mechanism.
+       \MH/ comes with a program, \man popaka(8), which generates the
+       additional information to be put in the mailsystem's alias file.
+\item  Delivery\hbreak
+       A special POP channel (for \MMDFII/) or POP mailer (for \SendMail/)
+       performs the actual delivery (\mh6 supplies both).
+       All it really does is just place the mail in the POP spool area.
+\end{enumerate}
+Clever mailsystem people will note that
+the POP mechanism is really a special case of the more general
+BBoards mechanism.
+\end{itemize}
+These two different philosophies are not compatible on the same POP service
+host: one or the other, but not both, may be run.
+
+In addition, there is one user-visible difference,
+which the administrator controls the availability of.
+The difference is whether the POP subscriber must supply a password to the POP
+server:
+\begin{itemize}
+\item  ARPA standard method\hbreak
+This uses the standard ARPA technique of sending a username and a password.
+The appropriate programs (\pgm{inc}, \pgm{msgchk}, and possibly \pgm{bbc\/})
+will prompt the user for this information.
+
+\item  \unix/ remote method\hbreak
+This uses the Berkeley \unix/ reserved port method for authentication.
+This requires that the two or three mentioned above programs be {\em setuid\/}
+to root.
+(There are no known holes in any of these programs.)
+\end{itemize}
+These two different philosophies are compatible on the same POP service host:
+to selectively disable RPOP for hosts which aren't trusted,
+either modify the \file{.rhosts} file in the case of POP subscribers being
+\unix/ logins,
+or zero the contents of network address field of the \man pop(5) file for the
+desired POP subscribers.
+
+The \pgm{inc} command also has two other switches when \MH/ is enabled for
+POP:
+\switch{pack~file} and \switch{nopack}.
+Normally,
+\pgm{inc} will use the POP to incorporate mail from a POP service host into
+an \MH/ folder (\eg{+inbox}).
+However,
+there are some misguided individuals who prefer to \pgm{msh} to read their
+maildrop.
+By using the \switch{pack~file} option,
+these individuals can direct \pgm{inc} to fetch their maildrop from the POP
+service host and store it locally in the named file.
+As expected, \pgm{inc} will treat the local file as a maildrop,
+performing the appropriate locking protocols.
+
+\section*     {Rcvmail hooks}
+In order to offer users of \MH/ increated rcvmail hook functionality,
+the \pgm{slocal} program has been upgraded to support the semantics of
+the \MMDFII/ mail-delivery mechanism.
+This means that users of \mh6 can maintain identical \file{.maildelivery}
+files regardless of the underlying transport system.
+See \man mhook(1) for all the details.
+
+\subsection*   {Field change in rcvpack}
+The \pgm{rcvpack} rcvmail hook now adds the field name \eg{Delivery-Date:}
+instead of \eg{Cron-Date:} to messages it \pgm{pack\/}s.
+
+\section*     {Other Changes}
+Here's the miscellany:
+
+\subsection*   {Continuation Lines}
+Alias files used by \MH/,
+display templates used by \pgm{mhl},
+and format files used by \pgm{forw}, \pgm{repl}, and \pgm{scan} all support
+a standard continuation line syntax.
+To continue a line in one of these files,
+simply end the line with the backslash character (`$\backslash$').
+All the other files used by \MH/ are in 822--format,
+so the 822--continuation mechanism is used.%
+\nfootnote{Looking back,
+it would have been best had all files in \MH/ used the 822--format.}
+
+\subsection*   {Modifications to show}
+The \switch{format}, \switch{noformat}, \switch{pr}, and \switch{nopr}
+options to \pgm{show} have gone away in favor of a more general mechanism.
+The \switch{showproc~program} option tells \pgm{show}
+(or \pgm{next} or \pgm{prev\/}) to use the named program as the \eg{showproc}.
+The \switch{noshowproc} option tells \pgm{show}, et. al.,
+to use the \man cat(1) program instead of a \eg{showproc}.
+As a result, the profile entry \eg{prproc} is no longer used.
+
+\subsection*   {Front-End to mhl}
+When outputting to a terminal,
+the \pgm{mhl} program now runs the program denoted by the profile entry
+\eg{moreproc}.
+If this entry is not present,
+the default is the UCB \pgm{more} program.
+If the entry is non-empty,
+then that program is spliced between \pgm{mhl} and the user's terminal.
+The author uses the \pgm{less} program as his \eg{moreproc}.
+
+Of course,
+if \pgm{mhl} isn't outputting to a terminal,
+then \eg{moreproc} is not invoked.
+
+\subsection*   {Switch change in inc}
+The \switch{ms~ms-file} switch in \pgm{inc} has been changed to
+\switch{file~name} to be more consistent.
+
+\subsection*   {Complex Expressions in pick}
+The \pgm{pick} command now handles complex boolean expressions.
+
+\subsection*   {Defaults change in prompter and burst}
+The \switch{prepend} option is now the default in \pgm{prompter}.
+The \switch{noinplace} option is now the default in \pgm{burst}.
+
+\subsection*   {Interactive option in rmf}
+The \pgm{rmf} program has been changed to support an \switch{interactive}
+switch.
+If given,
+then the user is prompted regarding whether the folder should be deleted.
+If the folder to be removed is not given by the user,
+this switch is defaulted to on.
+
+\subsection*   {Trusted Mail Interface}
+\MH/ now has an interface for so-called ``trusted mail'' applications.
+Although the modifications to \MH/ to support this are in the public domain,
+the actual library that \MH/ uses is not.
+Contact Professor David J.~Farber ({\sf address@hidden/}) for more information.

+\appendix{A}{MH Commands}
+\MH/ is composed of several \unix/ programs,
+which in theory are fairly simple and single-purposed.
+These commands are functionally grouped below:
+
+\psect{Composing Mail}
+\pitem{comp} compose a message.
+A program to originate a message.
+Usually, a special prompting editor front-end, \pgm{prompter},
+is used to fill-in a composition template with the addressees of
+the message, subject, and so forth.
+
+\pitem{dist} redistribute a message to additional addresses.
+A program that re-enters a message previously received by the user
+into the message transport system.
+Only new addresses are added;
+the body of the message is not changed in any way.
+
+\pitem{forw} forward messages.
+A program that encapsulates one or more messages in a new message draft.
+In addition, the user may add initial and/or closing comments.
+
+\pitem{repl} reply to a message.
+A program that constructs a reply to a message using a reply template.
+The template mechanism has sufficient generality to permit the user to
+``program'' the form of the reply draft based on the contents of the message
+being replied-to.
+
+\pitem{send} send a message.
+A program that posts a draft with the message transport system.
+The \pgm{send} program is
+usually invoked by one of the four preceding programs,
+and performs simple front-end pre-processing prior to invoking the
+\pgm{post} program.
+For example,
+if invoked in {\it push}'d mode,
+\pgm{send} will immediately relinquish control of the user's terminal and
+post the message in the background.
+If the posting fails,
+\pgm{send} will send back a failure notice to the user.
+If the user had \pgm{push\/}'d the sending of the draft,
+then by default
+the draft being sent is encapsulated in the failure notice.
+This permits easy \pgm{burst}'ing of the failure notice to retrieve the
+original draft.
+Otherwise,
+if the posting was successful,
+the draft is marked as having been sent.
+
+\pitem{whatnow} prompting front-end for send.
+A program which is called by  \pgm{comp}, et. al.,
+after the initial draft has been generated.
+The \MH/ user can specify a different \pgm{whatnow} program,
+which yields considerable extensibility.
+
+\pitem{whom} report to whom a message would go.
+A program which examines the addresses of the draft and expands
+all user-defined aliases contained therein.
+Optionally,
+\pgm{whom} may actually interact with the message transport system
+to determine the validity of the final addresses.
+This program is also usually invoked by \pgm{comp}, et.~al.
+
+\psect{Posting Mail}
+\pitem{ali} list mail aliases.
+A simple front-end to the \MH/ aliasing mechanism.
+
+\pitem{ap} parse addresses 822--style.
+A useful debugging tool for PostMasters who wish to examine how \MH/
+interprets an Internet address.
+
+\pitem{conflict} search for alias/password conflicts.
+Another program used by system administrators to check the consistency of
+\MH/ alias files, and portions of the local message transport agent.
+
+\pitem{install-mh} initialize the MH environment.
+A program which is automatically executed the first time a user issues an
+\MH/ command.
+This program performs once-only initialization of the user's \MH/ environment.
+
+\pitem{mhmail} send or read mail.
+A simple program generally used by other programs to generate messages.
+The \pgm{mhmail} command is similar in purpose to the old \pgm{BellMail}
+program.
+
+\pitem{post} deliver a message.
+A complex \MH/ back-end that interacts with the local message transport agent
+to enter messages through the posting slot.
+(See the description of \pgm{send} above).
+
+\psect{Reading Mail}
+\pitem{inc} incorporate new mail.
+A program that interacts with the local message transport agent
+to retrieve messages from the user's maildrop.
+
+\pitem{msgchk} check for waiting mail.
+A program which reports the status of mail waiting in the user's maildrop.
+
+\pitem{show} show (list) messages.
+A program which lists messages to its standard output
+(usually the user's terminal),
+possibly invoking another program to do the actual listing.
+Most users of \MH/ have \pgm{show} automatically call the \pgm{mhl} program
+to format the message.
+The \pgm{next} and \pgm{prev} programs are simply
+\eg{show\ next} and \eg{show\ prev},
+respectively.
+
+\pitem{mhl} produce formatted listings of MH messages.
+A program which displays a message as directed by a template.
+This permits the user to filter out uninteresting headers
+and re-arrange other headers to a particular preference.
+In addition to being invoked by \pgm{show},
+the \pgm{mhl} program is optionally also
+invoked by \pgm{forw} to format each message being forwarded;
+invoked by \pgm{repl} to format the body of a message being replied-to,
+if that message is being included in the reply draft;
+and,
+invoked by \pgm{post} to format a message being sent as a blind-carbon-copy.
+
+\pitem{rmm} remove messages.
+A program that removes messages from an \MH/ folder,
+optionally running a user-defined program instead of deleting them.
+If no program is given,
+the messages are ``softly'' removed,
+so they may possibly be recovered later.
+
+\pitem{scan} produce a one-line-per-message scan listing.
+A program that generates a scan listing for messages.
+Each line of the listing contains date, source, subject,
+and possibly the initial body of the message.
+
+\psect{Folder Handling}
+\pitem{folder} set/list current folder/message.
+A program used to list information concerning the current folder,
+or set the current folder and/or message.
+
+\pitem{folders} list all folders.
+A program to list information on all folders
+(actually, just a special case of the \pgm{folder} command).
+Since the \MH/ folder structure may be recursive,
+the user can indicate that \pgm{folders} should recursively examine all
+folders.
+
+\pitem{refile} file message(s) in (an)other folder(s).
+A program to move (or copy) messages from a source folder to one or more
+destination folders.
+
+\pitem{rmf} remove folder.
+A program that deletes a folder and all messages therein.
+
+\psect{Message Selection}
+\pitem{anno} annotate messages.
+A program to arbitrarily annotate messages.
+If the user so desires,
+after distributing, forwarding, or replying-to a message,
+\MH/ will automatically attach an annotation to the
+original message indicating the date and addresses.
+
+\pitem{mark} mark messages.
+A program to manipulate user-defined sequences (lists of messages).
+Usually, \pgm{mark} is not employed directly by the \MH/ user.
+
+\pitem{pick} select messages by content.
+A program to examine a list of messages and choose those which meet a
+particular selection criterion.
+The \pgm{pick} program is often used in \unix/ back-quoted operations to pass
+message sequences to other \MH/ commands.
+
+\pitem{sortm} sort messages.
+A program to sort a list of messages according to the date given in a
+particular field.
+
+\psect{Distribution List Handling}
+\pitem{bbc} check on BBoards.
+A front-end to run \pgm{msh} on a list of distribution lists which the
+user isn't current on.
+
+\pitem{bbl} manage a BBoard.
+A (depreciated) program used to manually manage the local archives of a
+distribution list.
+These functions (archiving, expunging) are performed automatically by \MH/.
+
+\pitem{burst} explode digests into messages.
+A program used to decapsulate messages from ARPA Internet digests.
+In addition,
+messages which have been encapsulated during forwarding
+(i.e., with \pgm{forw\/})
+can also be decapsulated using \pgm{burst}.%
+\nfootnote{Similarly, blind-carbon-copies may be decapsulated,
+though only socially mature users should do so.}
+
+\pitem{msh} MH shell (and BBoard reader).
+A monolithic program used to implement \MH/ commands on
+messages arranged in a single file (maildrop format).
+Useful
+since distribution lists are kept in this format to minimize consumption of
+system resources.
+
+\pitem{pack} compress a folder into a single file.
+A program which takes messages stored in \MH/ format and places them in a
+single file (using the same format known by \pgm{msh\/}).
+
+\psect{Interface to the \unix/ File System}
+\pitem{mhpath} print full pathnames of \MH/ messages and folders.
+A program which maps \MH/-style names into the \unix/ file naming convention.

+{\rightskip=0pt
+\lp
+The UCI version of the Rand Message Handling System (\MH/) is discussed,
+including important extensions.
+\MH/ is a powerful user agent which operates in the ARPA Internet and UUCP
+environments.
+In addition to the basic functions provided by a user agent,
+such as reading and sending mail,
+\MH/ has several distinguishing characteristics which give the user
+additional message handling capabilities.
+In particular,
+\MH/ provides mechanisms for organizing messages,
+tailoring its own behavior,
+and extending its functions.
+
+\lp
+This document describes \MH/ from several perspectives.
+Particular emphasis is given to:
+the \MH/ user environment,
+advanced features of \MH/ which have proven to be particularly useful for
+sophisticated users of electronic mail,
+\MH/'s potential as a record manager,
+and
+\MH/ as a part of a distributed mail environment.
+Although \MH/ as been widely used since its creation in 1979,
+a discussion of its perspectives and functionality has not appeared in the
+open literature.

+\section{Introduction}                         % mtr
+\tagfigure{0}{\MTS/ model}{mtsmodel}
+
+The UCI version of the Rand Message Handling System, \MH/,
+is a user agent.
+In the interests of brevity,
+we dispense with the usual definition of terms,
+refer the reader to Figure~\mtsmodel,
+and simply note that \MH/ is not responsible for delivering mail.
+Rather,
+it interacts with a {\it message transport system}, \MTS/,
+at two interfaces:
+it sends mail by placing it through a {\it posting slot} to the \MTS/,
+and it receives mail by retrieving it through a {\it delivery slot} from the
+\MTS/.
+Besides these two \MTS/-specific activities,
+the tasks which \MH/ addresses are:
+the composition of messages
+(which may, or may not, be in reference to previously sent messages),
+the reading of messages,
+and the organization of messages.
+
+\MH/ was originally developed by the Rand Corporation,
+and initially was proprietary software.
+The Department of Information and Computer Science at
+University of California, Irvine,
+shortly after joining the Computer Science Network (CSnet),
+acquired a copy of \MH/,
+and began additional development of the software.
+Since that time,
+the Rand Corporation has declared \MH/ to be in the public domain,
+and the UCI version of \MH/ has passed through four major releases.
+
+Much credit must be given to the initial designers and implementors of \MH/:
+Bruce Borden, Stockton Gaines, and Norman Shapiro.
+Although \MH/ has suffered significant development at UCI
+since Rand's initial release,
+the fundamental concepts of \MH/'s environs have remained nearly unchanged.
+In addition,
+the current maintainers of \MH/ gratefully acknowledge the comments of the
+many sites which have run various releases of \MH/ in the past.
+
+\MH/ runs on different versions of the \unix/ operating system
+(such as 4.2\bsd/~\unix/ and various flavors of v7~\unix/).
+In addition,
+\MH/ supports four different \MTS/ interfaces:
+\SendMail/\cite{EAllm83},
+the standard mailer for 4.2\bsd/ systems;
+\MMDF/\cite{DCroc79} and \MMDFII/\cite{DKing84},
+the Multi-Channel Memo Distribution Facility developed by the University of
+Delaware
+which forms the software-backbone for CSnet\cite{DCome83} mail relays service;
+SMTP,
+the ARPA Internet Simple Mail Transfer Protocol\cite{SMTP};
+and,
+a stand-alone delivery system.
+
+The organization of this paper is straight-forward,
+given space considerations.
+Initially,
+the \MH/ philosophy of mail handling is presented,
+along with a description of the environment which the \MH/ user is given to
+process mail.
+Following this,
+certain advanced features of \MH/ are discussed in more detail.
+In particular,
+the notion of a {\it draft folder} is introduced,
+which permits the handling of multiple drafts during composition.
+In addition,
+message selection facilities are described.
+Next,
+two different aspects of \MH/'s power as a software system are discussed:
+record handling, in which \MH/ facilitates record processing systems;
+and,
+how \MH/ can be employed in a distributed mail environment.
+This latter section raises questions as to the location of the posting and
+delivery slots,
+along with authentication mechanisms.
+Finally,
+we conclude by discussing areas of future development which \MH/ may endure.
+
+Although familiarity with \MH/ is not assumed on the part of the reader,
+some knowledge of the \unix/ operating system is useful.
+Appendix~A gives a short synopsis of the \MH/ commands.
+
+\section{The \MH/ Philosophy}                  % mtr
+Although \MH/ has many traits which tend to differ it from other user agents,
+the design aspect which fundamentally influences the interface between \MH/
+and the user is that it is composed of many small
+programs instead of one very large one.
+This architecture gives \MH/ much of its strength,
+since intermediate and advanced users are able to take advantage of this
+flexibility.
+
+The key to this flexibility is that the \unix/ shell
+(usually the {\it C} shell or the {\it Bourne} shell),
+is the user's interface to \MH/.
+This means that when handling mail,
+the entire power of the shell is at the user's disposal in addition to the
+facilities which \MH/ provides.
+Hence,
+the user may intersperse mail handling commands with other commands in an
+arbitrary fashion,
+making use of command handling capabilities that the user's shell provides.
+
+Furthermore,
+rather than storing messages in a complicated data structure
+within a monolithic file,
+in \MH/, each message is a \unix/ file,
+and each folder (an object which holds groups of messages)
+is a \unix/ directory.
+That is,
+the directory and file structure of \unix/ is used directly.
+As a result,
+any \unix/ file-handling command can be applied to any message.
+
+To the novice,
+this may not make much sense or may not seem important.
+From three years of observation, we have seen that
+as users of \MH/ have become more experienced
+they have found this capability to be quite attractive.
+In addition,
+this approach is often quite pleasing to system implementors,
+because it minimizes the amount of coding to be performed
+and,
+given a modular design,
+changes to the software system can be maintained easily.
+Our empirical findings confirm our theoretical expectations regarding the
+\MH/ architecture.
+
+Having described how \MH/ fits into the \unix/ environment,
+we now discuss the mail handling environment which is available to the \MH/
+user.
+
+\subsection{The \MH/ Environs}                 % jns
+\MH/ provides a complementary environment to the user's shell.
+While the shell maintains a context related to the user's focus in the file
+system (a {\it current working directory\/}),
+mail handling is performed in a separate mail folder context.
+Operations on mail can therefore be
+performed entirely without regard to the current file system context,
+although \MH/ does not prevent the user from making use of that context.
+Certain mail handling functions do make use of information
+maintained by the shell.
+For instance, by setting certain shell parameters,
+called {\it environment variables},
+alternate mail handling contexts can be selected.
+
+\MH/ conventions often have direct analogs to shell or file system
+conventions.
+The shell has a current working directory; \MH/ has a current mail folder.
+When the user begins a session on the system,
+the user's ``home directory'' is the base context;
+\MH/'s default base area, the \Mail/ directory, 
+is found under the user's home directory.
+The user's default shell parameters are set upon beginning a new
+session from a startup profile
+(called \file{.profile} for \pgm{sh} users
+or \file{.cshrc} for \pgm{csh} users);
+the default parameters for \MH/ commands are taken from a file called
+\profile/ in the user's home directory.
+The shell has an {\it environment\/};
+\MH/ has a \context/ file.
+Each of the user's directories has files;
+each of the user's \MH/ folders has messages.
+
+These parallels have a basis not only in \MH/'s high level mail
+handling model,
+but also in the way low level shell and file
+system conventions have been abstracted to implement \MH/ conventions.
+Directories are folders; files are messages.
+The \Mail/ directory forms the root of a virtual file subsystem within
+which the user operates on mail without disturbing files outside this
+mail handling domain. 
+
+\tagfigure{1}{\MH/ File Subsystem\\(directories are shaded)}{MHfiles}
+\tagdiagram{2}{Elaborated \MH/ Profile}{elab}
+\subsection{The \MH/ Profile}
+The \profile/ contains plaintext that describes the user's default mail
+handling parameters.
+An example of an elaborated profile is shown in Figure~\elab.
+
+Each line in the profile consists of an \MH/ parameter name terminated
+with a colon (`:') followed by parameter values.
+In this example,
+``global'' parameters are listed in the first few lines,
+with program-specific parameters following.
+Each \MH/ program examines global parameters as well as any parameter
+with the same name by which the program was invoked.
+For example,
+the \pgm{comp} program, which is used to compose new messages to be sent,
+examines the entries:
+\medskip
+{\advance\leftskip by2\parindent
+\uitem{Path}
+The path parameter specifies the name of the \MH/ root directory.
+This is normally named \Mail/.
+
+\uitem{Editor}
+The editor parameter specifies which text editor is first invoked to create
+the header information and body of a message draft.
+In most cases, this editor is the \MH/ default editor, \pgm{prompter}.
+
+\uitem{Draft-Folder}
+This parameter specifies a folder within which new message drafts
+are to be created.
+The draft folder mechanism is an advanced feature of \MH/ that is
+given separate treatment in a later segment of this paper.
+
+\uitem{comp}
+The program-specific parameter examined by \pgm{comp} lists
+user-default options.
+\par}
+\medskip
+
+\noindent
+Other programs invoked by \pgm{comp}
+(e.g. \pgm{prompter} and \pgm{send\/}) would examine their own profile 
+entries as well.
+\MH/ programs have reasonable compiled-in defaults and also permit options to
+be specified on the shell command line with which the programs are invoked.
+The order of override precedence is: command line options first,
+\profile/ options second, and compiled-in defaults last.
+
+Each program option is prefixed by a dash (`-') following the \unix/
+convention.
+Unlike most \unix/-style options,
+however, the options are words rather than single letters.
+An option may be abbreviated to an unambiguous prefix.
+Each \MH/ program has a \switch{help} option that
+displays a brief summary of the program's available options.
+
+\subsection{Folders and Messages}
+In a typical paper-oriented office,
+new correspondence arrives and is stacked in an ``in box'',
+while outgoing correspondence is placed in an ``out box''.
+Processed material is stored in
+appropriately labelled folders and filed away for future reference.
+This state of affairs is modelled in \MH/ with {\it folders}
+and {\it messages},
+which are simply text files (one message per file) stored
+under the folder directories.
+Most of the user's folders are kept under the \Mail/ directory.
+
+A folder is given an alphanumeric name permissible within the \unix/ file
+system structure,
+and each message stored therein is given a numeric name in the range 1..1999.
+The upper bound on message numbers was
+selected for efficient access to an internal representation,
+an array of bits (a ``bit set''),
+with each bit indicating the presence or
+absence of a message with a number in the range 1..1999.
+This internal representation also restricts the order of multiple
+message reference to an ascending numerical sequence.
+Other representations have been studied
+(e.g., an unsorted sparse array of integers),
+but have been rejected for reasons of efficiency.
+Folders may contain subfolders,
+corresponding to \unix/ tree-structured directories.
+For the sake of completeness,
+it might be said that ``sub-messages'' exist insofar as message ``digests'',
+which nest messages inside other messages,
+are supported by certain advanced \MH/ functions.
+
+The current working folder is the default folder selected for almost
+all \MH/ commands.
+To select explicitly a folder for mail handling
+commands entails specifying the name of the folder, prefixing the name
+with a plus-symbol (`+').
+An example is: \example refile\ 1\ 2\ 3\ +chron/yr.1984\endexample
+This command re-files the selected messages
+(\file{1}, \file{2}, and \file{3} here)
+from the current working folder to a subfolder under the
+folder \file{chron} named \file{yr.1984}.
+To see the folder/subfolder relationship, refer to Figure~\MHfiles.
+
+The plus-symbol notation is specific to those folders immediately
+subordinate to the \Mail/ directory.
+This is analogous to ``absolute pathnames'' in \unix/---those
+files whose positions in the file system
+hierarchy are given starting with the system root,
+names prefixed with the slash character (`/').
+To specify folders subordinate to the current working folder,
+an at-sign (`@') is substituted for (`+').
+It is permitted to use \unix/ dot notation to specify parent folders.
+Referring to Figure~\MHfiles,
+if the current working folder were \eg{+chron/yr.1985},
+then the command \example folder\ @../yr.1984\endexample
+\noindent
+selects the subfolder \file{yr.1984} in the parent directory
+\file{chron}, as the new current working folder.
+While the current working folder is normally the default, it may be
+specified explicitly as address@hidden
+
+\subsection{The Context File}
+The \profile/ contains static information about the user's
+preferences.
+A \context/ file, contained in the \Mail/ directory,
+contains the current mail handling environment information,
+which changes as different folders, messages, and named message lists
+(called {\it message sequences\/})  are selected, created, and updated.
+This information is retained between invocations of \MH/ commands,
+and is preserved across system sessions.
+
+\tagdiagram{3}{Elaborated Reply Template}{replcomps}
+\subsection{Templates}
+The message draft composition functions
+(\pgm{comp}, \pgm{repl}, \pgm{forw}, and \pgm{dist\/})
+use certain default header formats,
+which may be changed by the user through the use of message templates.
+The exact format of a template may vary among commands.
+An example of an elaborated template for the reply command \pgm{repl} is
+shown in Figure~\replcomps.
+
+This template specifies how the automatically-generated header for a
+draft message in reply to a source message is to be formatted.
+The syntax is capable of directing output of header lines based on the
+presence or absence of other header lines in the source message.
+
+Other kinds of templates are used to specify the display formats of
+messages, or to specify the way that messages are to be included in
+other messages.  This is similar to the functionality provided by BBN
+Hermes\cite{HERMES},
+another powerful mail handling system for \tops20/ based systems.
+
+\subsection{Explaining All This to New Users}
+There do exist people who do not like \MH/.%
+\nfootnote{At UCI, these
+people are reported to be weeded out at an early stage and quietly taken to the
+Ministry of Love to be made {\it uncrimethinkful}.}
+The emerging pattern of complaints from such people indicates that \MH/
+accentuates their perceptions of the deficiencies of \unix/,
+to wit, lack of interactivity and lack of easily found help facilities.
+Also,
+some feel that the proximity of the mail handling environment to the
+operating system is a distraction, rather than an asset.
+There have been some attempts to make \MH/ more accessible to users who prefer
+menu-oriented or monolithic mail system interfaces.%
+\nfootnote{For example,
+\pgm{mhe} from Brian Reid of Stanford University
+and \pgm{emh} from Marshall Rose
+are instances of macro packages for James Gosling's \EMACS/ extensible editor,
+while the \pgm{hm} program from Jim Guyton of the Rand Corporation is a
+monolithic \MH/ interface.
+As of this writing,
+none of these programs is documented in the literature.}
+
+In truth,
+users new to \unix/ do not always acclimate to \MH/ easily.
+The command set is undistinguishably mixed in with all other \unix/
+utilities, and it is not easy, without aid of a manual,
+to pick out the necessary commands.
+\MH/ does not provide any ``hand-holding'' to guide
+the user through a minimally useful command subset.
+
+Another problem is that the initial default user profile is too often sparse,
+containing only a \eg{Path:} parameter.
+\MH/ commands will perform adequately without specific information
+in the profile,
+so new users often neglect optionally useful \MH/ capabilities,
+eventually becoming frustrated with the limited default capabilities,
+yet unable to determine without researching through the user's manual,
+the necessary options that would solve their problems.
+
+The currently available means for learning how to use \MH/ are:
+\medskip
+{\advance\leftskip by 2\parindent
+\item{$\bullet$}
+One-on-one tutoring by knowledgeable \MH/ users,
+which has so far shown the best results with new users.
+
+\item{$\bullet$}
+Consulting the {\it \MH/ Tutorial\/}\cite{MRose84b},
+or the {\it \MH/ User's Manual\/}\cite{MRose85a}.
+
+\item{$\bullet$}
+Using the \pgm{msh} (``\MH/ shell'') program as a training shell to read
+bulletin boards.
+The \pgm{msh} command is an interactive program that provides some help
+messages and can list available \MH/ commands.
+\par}
+\medskip
+
+\noindent
+No on-line tutorial materials are presently distributed with the \mh5
+system, although there are some plans in the works to provide a program
+to help with setting up the user profile that would also provide
+operational tips for \MH/ and \unix/. 
+
+It should be noted that these perceived defects of \MH/ do not affect its
+utility any more than analogous problems with any operating system
+will diminish its actual capabilities.
+Users may quarrel with the means chosen for orchestrating \MH/,
+but the fact remains that \MH/ is a very
+useful set of mail handling tools that is flexible,
+infinitely interoperable with other \unix/ text handling tools,
+and yet simple enough for new users to grasp once they are given the 
+proper start.
+The fact that better tutorial materials and training do not exist only means
+that some further work needs to be done in the area of user-education.
+
+\section{A Few Advanced Features}              % mtr
+We now consider certain advanced features in \MH/.
+These features have been chosen to demonstrate some useful capabilities
+available to the \MH/ user.
+It should be noted that many capabilities of \MH/,
+such as shell scripts for extensibility,
+mail delivery hooks,
+the personal aliasing facility,
+and so forth,
+are not described here for lack of space.
+
+\subsection{Draft Folders}                     % jns
+The {\it draft folder} facility provides a method by which several
+message drafts can be simultaneously composed and maintained until
+sent.
+The rationale for this is that partially composed message drafts,
+perhaps elaborate sets of separate messages,
+can be incrementally completed,
+while a folder provides a consistent organization for drafts in progress.
+This is comparable to similar situations in the ``paper world'' where
+contracts, business correspondence, and other communications,
+rather than being created serially with each posted in turn before composing
+the next,
+are usually left in various stages of
+completion before they are eventually mailed.
+
+The \eg{Draft-Folder:} parameter value in the \MH/ profile is used to
+specify a default draft folder,
+where each draft is given a number and an ``artificial'' date stamp.
+Provided that the proper header fields have been completed,
+a \pgm{scan} listing of the draft folder provides a summary of
+each draft in progress:
+to whom the message is to be sent,
+the subject,
+the date of the draft's initial creation and optionally,
+the current size of the draft in terms of characters.
+Experienced users of \MH/ may often keep as many as five to ten unfinished
+drafts in their draft folder.
+``Draft clutter'' can be remedied easily with the \pgm{rmm} command.
+
+\subsection{Message Selection}                 % stef
+\MH/ commands accept {\it message sequence} specifications to specify which
+\arg{msg} or \arg{msgs} are to be operated upon.
+Here are some examples:
+\example scan\ 1\ 3\ 5\ 19\ 185\endexample
+to get a scan listing of messages 1, 3, 5, 19 and 185.
+\example scan\ pseq\endexample
+to get a scan listing of whatever message sequence was given to the previous
+MH command (in this case 1, 3, 5, 19, and 185).
+\example show\ first\ last\endexample
+to get a display of the first and last messages in the folder.
+The \MH/ sequences named \eg{first} and \eg{last} are system defined pseudo
+sequences which act like explicit sequences when given to MH commands.
+Others are \eg{cur}, \eg{next}, \eg{prev},
+and \eg{all} which respectively specify the ``current'' message,
+the ``next'' after cur,
+the ``previous'' message before cur,
+or ``all'' messages in the current-folder.
+The \pgm{scan} assumes \eg{all} while show assumes \eg{cur},
+unless overridden on the command line.
+Over-ride precedence is: command-line first,
+\profile/ second,
+and compiled-in default last.
+
+Users can define additional sequences for similar use,
+but must avoid using reserved names.
+A few optional sequence names have been preempted by \MH/,
+such as \eg{pseq} to mean the
+``sequence used by the previous MH command,''
+and \eg{unseen} to mean the ``messages not yet seen by the user.''
+Sometimes these preempted names can be changed by resetting them in the
+user's \MH/ profile,
+but these facilities are beyond the scope of this discussion.
+
+The mark command can be used to set the values for user-defined sequences:
+\example mark\ 1\ 3\ 5\ -seq\ zzz\\
+        mark\ 4\ 5\ 9\ -seq\ zzz\ -nozero\endexample
+will create a user-sequence named \eg{zzz} and put the sequence \eg{1 3 5}
+in it.
+The \pgm{mark} command assumes that any prior content in an
+existing user-sequence should be ``zeroed'' before the new sequence value is
+recorded.
+This can be prevented with a \switch{nozero} switch on the command line,
+to add \eg{4 5 9} to the original \eg{1 3 5} to yield \eg{1 3 4 5 9}.
+\example mark\ pseq\ zzz\ -seq\ zzznew\endexample
+will create a new sequence named \eg{zzznew} and set its value to the combined
+(inclusive or) of the existing user-sequences in \eg{pseq} and \eg{zzz} for
+its value.
+
+Another more powerful way to set the values of a user-sequence is with
+the pick command, which provides full string search capabilities:
+\example pick\ -from\ mrose\ -seq\ yyy\\
+        pick\ -from\ mrose\ -seq\ yyy\ -list\endexample
+will search though all the \eg{From:} fields in the current folder for the
+string \eg{mrose} and place the list of ``hits''
+in the sequence named \eg{yyy}.
+The \switch{list} switch will cause the resulting list to also be displayed on
+the user's terminal.
+If no \switch{seq\ name} switch is given,
+pick will assume \switch{list}
+and will simply display the resulting list of hits on the user's terminal.
+
+This \switch{list} behavior of pick allows users to take advantage of the
+\unix/ backquoting facility to embed searches in other \MH/ commands.
+\example scan\ \bq{pick\ -from\ mrose}\endexample
+will produce a scan listing of \switch{from\ mrose} hits because the
+\unix/ shell will spawn a process to execute the
+\eg{pick\ -from\ mrose} segment and return the \switch{list}
+results as the message sequence to be scanned.
+\example mark\ pseq\ -seq\ zzz\endexample
+could then be used to capture the ``previous sequence'' in zzz for later use.
+
+One last facility should be mentioned here.
+It is also possible to negate a sequence to specify a new sequence.
+The default negation string is \eg{not}.
+\example scan\ notzzz\\
+        mark\ notzzz\ -seq\ zzznot\endexample
+will give the user a scan listing of all the messages in the current folder
+that are not included in the sequence \eg{zzz}.
+The mark example will of course record the negation of zzz in zzznot.
+It is a bad idea to use the string \eg{not} as the beginning of any
+user-sequence name,
+if \eg{not} is defined as the negation string.
+(Users can choose a different negation string.)
+
+From this discussion,
+it should be clear that \MH/ provides a uniform set of ways to capture
+and use sequences to augment the user's short- and long-term
+memory and to manipulate lists of interesting messages.
+User-sequences are normally stored as RFC822 labeled text lines in a file
+(e.g., \sequences/)
+in the folder with the messages referred to in the sequence.
+If a user does not have write access to a folder,
+then the \MH/ \pgm{mark} and \pgm{pick} commands will
+create a ``private'' sequence in the user's \context/ file.
+Switches are available to give the user control over
+the choice of \switch{private} or \switch{public} sequence options.
+
+Since user-sequences are stored as ordinary text lines in RFC822 labeled
+fields,
+there is no prohibition against someone writing programs to perform
+any kind of useful manipulation on \MH/ sequences.
+Boolean operators can be implemented,
+or complex indexing structures could be developed to serve special purposes.
+If a DBMS can utilize \unix/ pathnames or \MH/ \arg{+folder} and
+message names,
+then the full power of the DBMS might be applied.
+The intention of \MH/ development teams has always been to leave open the
+widest possible array of options for later extension.
+The only restrictions should be the user's ingenuity,
+programming prowess, and the available machine resources.
+Unfortunately these resources always seem to be available in
+limited quantities.
+
+\subsection{Distribution Lists}                        % mtr
+\MH/ has a convenient interface to the UCI BBoards facility\cite{MRose84a}.%
+\nfootnote{The UCI BBoards facility can run under either the \MMDF/ or
+\SendMail/,
+or in a more restricted form under stand-alone \MH/.}
+This facility permits the efficient distribution of interest group messages
+on a single host,
+to a group of hosts under a single administration,
+and to the ARPA Internet community.
+
+Described simply, an interest group is composed of a number of subscribers
+with a common interest.
+These subscribers post mail to a single address, known as a
+{\it distribution} address (e.g., {\tx address@hidden).
+From this distribution address, a copy of the message is sent to each
+subscriber.
+Each group has a {\it moderator},
+which is the person that runs the group.
+This moderator can usually be reached at a special address,
+known as a {\it request} address (e.g., {\tx address@hidden).
+Usually, the responsibilities of the moderator are quite simple,
+since the mail system handles distribution to subscribers automatically.
+In some interest groups,
+instead of each separate message being distributed directly to subscribers,
+a batch of (related) messages are put into a {\it digest} format by the
+moderator and then sent to the subscribers.
+Although this requires more work on the part of the moderator
+and introduces delays,
+such groups tend to be better organized.
+
+Unfortunately, some problems arise with the scheme outlined above.
+First, if two users on the same host subscribe to the same interest group,
+two copies of the message will be delivered.
+This is wasteful of both processor and disk resources at that host.
+
+Second,
+some groups carry a lot of traffic.
+Although subscription to a group does indicate interest on the part of a
+subscriber,
+it is usually not interesting to get 50 messages or so delivered to 
+the user's private maildrop each day,
+interspersed with {\it personal} mail,
+that is likely to be of a much more important and timely nature.
+
+Third, if a subscriber's address in a distribution list 
+becomes ``bad'' somehow and causes failed mail to be returned,
+the originator of the message is normally notified.
+It is not uncommon for a large list to have several bogus addresses.
+This results in the originator being flooded with ``error messages'' from
+mailers across the Internet stating that a given address on the list was
+bad.
+Needless to say,
+the originator usually does not care if the bogus addresses got a copy
+of the message or not.
+The originator is merely interested in posting a message
+to the group at large.
+On the other hand,
+the moderator of the group does care if there are bogus addresses on the list,
+but ironically does not receive notification.
+
+To solve all of these problems,
+the UCI BBoards facility introduces a new entity into the picture:
+all interest group mail is handled by a special component of the mail system.
+The distribution address maps to a special {\it channel} that performs
+several actions.
+First, if local delivery is to be performed,
+then a copy of the message is placed in a global maildrop for the interest
+group with a timestamp and a unique number.
+Local users can read messages posted for the interest group by reading this
+``public'' maildrop.
+Second, if further distribution is to take place,
+a copy of the message is sent to the distribution address in such a way that
+if any of the addresses are bogus,
+failure notices will be returned to the local maintainer of the group
+address list, rather than the originator of the message.
+
+This scheme has several advantages:
+First, messages delivered to the local host are processed and saved once
+in a globally accessible area.
+The UCI BBoards facility supports software which allows a user to query an
+interest group for new messages and to read and process
+those messages in the \MH/-style.
+Second, once a host administrator subscribes to an interest group,
+each user can join or quit the list's readership without
+contacting anyone.
+Third, a hierarchical distribution scheme can be constructed to
+reduce the amount of delivery effort.
+Fourth, errors are prevented from propagating.
+When an address on the distribution list goes bad,
+the list moderator who is immediately responsible for the address is notified.
+If a local moderator does not exist,
+then the local PostMaster is notified (not the global group moderator).
+
+In addition to solving the problems outlined above,
+the UCI BBoards facility supports several other capabilities.
+BBoards may be automatically archived in order to conserve disk space and
+reduce processing time when reading current items.
+Also,
+the archives can be separately maintained on tape for access by interested
+researchers.
+
+Special alias files may be generated which allow the \MH/ user to shorten
+address type-in.
+For example, instead of sending to {\tx address@hidden,
+a user of \MH/ usually sends to \eg{SF-Lovers} and the \MH/ aliasing
+facility automatically makes the appropriate expansion in the headers of the
+outgoing message.
+Hence,
+the user need only know the name of an interest group and not its global
+network address.
+
+Finally, the UCI BBoards facility supports {\it private} interest groups
+using the \unix/ group access mechanism.
+This allows a group of people on the same or different machines to conduct a
+private discussion.
+
+The practical upshot of all this is that the UCI BBoards facility automates
+the vast majority of BBoards handling from the point of view of both the
+PostMaster and the user.
+
+\MH/ provides three programs to deal with interest groups.
+The \pgm{bbc} program is used to check on the status of one or more groups,
+and to optionally start an \MH/ shell on those groups which the user is
+interested in.
+The \pgm{bbl} program can be used to perform manual maintenance on a
+discussion group beyond the normal automatic capabilities of the UCI BBoards
+facility.
+Finally,
+the \pgm{msh} program implements an \MH/ shell for reading BBoards,
+in which nearly all of the \MH/ commands are implemented in a single program.
+
+Observant readers may note that the use of \pgm{msh} is contrary to the \MH/
+philosophy of using relatively small, single-purposed programs.
+Sadly,
+the authors admit that this is true.
+In an effort to avoid some problems with shared-access and message naming
+conventions (which are beyond the scope of this paper),
+BBoards are kept in maildrop format (monolithic) instead of folders.
+Some research has gone into overcoming this problem in order to restore
+\MH/'s purity of purpose,
+but all solutions proposed to date are either unworkable or require
+significant recoding of \MH/'s internals.
+
+\subsection{Encapsulation}                     % mtr
+As described above,
+some interest groups appear in digest form.
+This means that the messages which appear in such a forum actually
+encapsulate other messages in their body.
+It turns out that the generation of a digest is not at all unlike the
+generation of a draft which forwards one or more messages.
+In RFC934\cite{MRose85b},
+a method is proposed to standardize message encapsulation for the ARPA
+Internet community.
+\MH/ uses this method for the generation of digests,
+forwardings,
+and blind-carbon-copies.
+
+A key requisite for using an encapsulation technique for digests and
+forwardings is the ability to later decapsulate the contents.
+Without this ability,
+the forwarded messages are of little use to the recipients because they can
+not be distributed, forwarded, replied-to, searched-for,
+or otherwise processed as separate individual messages.
+In the case of a digest,
+a bursting capability is especially useful.
+Not only does the ability to burst a digest permit a recipient of the digest
+to reply to an individual digestified message,
+but it also allows the recipient to selectively process the other messages
+encapsulated in the digest.
+
+For example,
+a single digest issue usually contains more than one topic.
+A subscriber may only be interested in a subset of the topic discussed in a
+particular issue.
+With a bursting capability,
+the subscriber can burst the digest,
+scan the headers,
+and process those messages which are of interest.
+The others can be ignored,
+if the user so desires.
+
+Note that with proper encapsulation technology,
+one can argue for the re-distribution of messages simply becoming
+special cases of message forwarding.
+For example,
+the NBS Standard for Mail Interchange\cite{FIPS98}
+and the recent CCITT draft on Mail Handling Systems standards\cite{X.400}
+both discourage the re-distribution facility in favor of forwarding
+by encapsulation.
+
+\subsection{Encapsulation and Blind-Carbon-Copies} % mtr
+Many user agents support a blind-carbon-copy facility.
+\MH/ implements this using a form of encapsulation.
+It may not be apparent to the reader as to why encapsulation of the original
+message is a good way to deliver blind-carbon-copies.
+With a blind-carbon-copy facility,
+two types of addressees are possible in the draft to be sent:
+{\it visible} and {\it blind}.
+The visible recipients are listed as addresses in the \eg{To:} and \eg{cc:}
+fields,
+and the blind recipients are listed in the \eg{Bcc:} fields of the draft.
+The idea behind this facility is that copies of the draft which are
+delivered to the \eg{To:} and \eg{cc:} recipients should show the visible
+recipients only.
+
+A major concern with a blind-carbon-copy facility
+is that blind recipients should be prevented from accidentally replying to the
+message in such a way that the visible recipients are included as addressees
+in the reply.
+
+There are several methods to implement this facility.
+Most rely on posting two drafts with the \MTS/.
+One draft is destined for visible recipients,
+and simply lacks the \eg{Bcc:} fields of the original draft.
+The second draft is destined for the blind recipients.
+The question then arises as to what form this latter draft posted should take.
+
+One approach might be to disable the \eg{To:} and \eg{cc:} fields of the
+draft sent to the blind recipients
+(e.g., by prefixing the string \eg{BCC-} to these fields).
+Unfortunately,
+this is often very confusing to the blind recipients
+because it differs from what the visible recipients got.
+Although accidental replies are not possible,
+it is often difficult to tell that the message received is the result of a
+blind-carbon-copy.
+
+The method used by \MH/ is to post two drafts,
+a visible draft for the visible recipients,
+and a blind draft for the blind recipients.
+The visible draft consists of the original draft without any \eg{Bcc:} fields.
+The blind draft contains the visible message as a forwarded message.
+The headers for the blind draft contain the minimal RFC822 headers
+(\eg{From:} and \eg{Date:})
+and,
+if the original draft had a ``Subject:'' field,
+then this header field is also included.
+In addition,
+\MH/ alerts the recipient that the message is a blind-carbon-copy by
+placing this information in the initial encapsulation information in the
+blind recipient's copy.
+This scheme prevents inadvertent replies while allowing the recipient
+full access to an exact copy of what was sent to the visible recipients.
+
+\section{\MH/ as a Record Handler}             % stef
+Although message format standards such as RFC822
+(and its predecessors) were originally devised to facilitate
+computer processing of interpersonal messages,
+there is no special reason why the concept should be
+limited to interpersonal message processing.
+Messages are just one of a variety of useful record forms that might
+be created in one place and transfered to another for processing.
+In this regard,
+RFC822 wisely left open the option for higher level applications to use
+arbitrary header names or field contents by proscribing \MTS/ use
+of header names beginning with \eg{X-}.
+
+\MH/ carries though on this idea by allowing the \pgm{pick} command
+to accept any arbitrary field name for string searches,
+so MH users can select on any arbitrary field name without prior definition.
+Beyond this,
+since all messages are simply files in \unix/ directories,
+applications can be developed to apply any programmable process to
+any selected message.
+
+For example,
+a {\it Time Card Form} might be called up by an \MH/ user with
+\example comp\ -form\ timecomps\endexample
+to enter time and attendance information into \eg{X-time$\tdots$:} fields in a
+draft message record.
+The \file{timecomps} form would include the address of a
+supervisor who should validate the information,
+along with empty fields to be filled in with data.
+In fancy applications,
+this might be done with a sophisticated interactive data entry tool
+which would validate entered information,
+but this is an open choice within the \MH/ framework.
+Another
+alternative would be to use a received message as the blank form to add a
+degree of central control over time and attendance reporting forms.
+
+Receiving supervisors could simply register approval by using the \MH/
+\pgm{dist} command to resend subordinates' time cards to higher approval
+levels, or
+to send them to a time card collection address.
+The \MH/ \pgm{dist} command automatically inserts ``ReSent'' header fields
+showing who resent it and the resending date.
+Alternatively,
+the MH \pgm{forw} command could be used to transfer a batch of approved time
+cards to the next processing station.
+If desired, a new ``approval'' command could be programmed to provide a more
+trusted authentication, perhaps with encryption of the content.
+Trusted mail systems, such as \trustedmail/\cite{MRose85c},
+are becoming available for this purpose.
+
+At the final collection destination,
+an automated User Agent could be programmed to directly load the data into
+the Time and Attendance DBMS by
+parsing and decoding the data contained in the \eg{X-time$\tdots$:} fields.
+It might be noted that while the RFC822 does not restrict the
+internal forms of messages,
+it is necessary to conform to the interchange standard if specialized filters
+for message headers are not to be built to serve as {\it export laundries}
+(a term originating with Stephen H.~Willson to describe conformance
+transformations in \Ada/).
+
+\subsection{Mapping Between Record Modes (DBMS/MHS)}
+This time and attendance example suggests that it is possible to define
+one-to-one mappings between RFC822 fields and DBMS data elements.
+For every DBMS data element definition,
+there is a potential corresponding RFC822 transferable equivalent
+definition which can facilitate mail transfers of record information.
+Indeed,
+a large portion of the definitional work is already done where a Data Base
+has already been defined.
+All that remains is to define the RFC822 equivalents.
+
+The suggestion that a batch of time cards be forwarded inside a ``cover''
+message implies that it is possible in the \MH/ framework to recursively
+bundle messages within messages, and be able to recover the originals for
+separate processing at a receiving destination.
+The \MH/ \pgm{burst} command can be applied recursively for this purpose
+because \MH/ encapsulation uses an unambiguous scheme to delimit messages
+that are enclosed inside other messages.
+Thus,
+it should be possible to extract a structured set of records from a DBMS
+and mail the set to a foreign site for processing, or reinsertion into
+another DBMS.
+As long as the DBMS data element definitions
+correctly correspond to the RFC822 definitions,
+it is not even necessary
+for the source and destination DBMS systems to be the same.
+
+From this discussion,
+it is concluded that the \MH/ framework can be useful
+for building distributed record handling systems where people at widely
+scattered locations must create and submit record forms for processing
+at distant locations.
+This might prove to be especially effective when
+a mail system is also needed for other communication purposes.
+A network of sales offices is a good example,
+where general message service would be used for communications
+with remote manufacturing and distribution centers,
+and could also be used for an order entry system.
+
+Another example might be for structured communications, as occur in
+requisition and purchasing systems.
+Requisitions could be filled in and mailed to approval offices,
+and resent or forwarded to others for action.
+At some point,
+the requisitions could flow into other other more suitable
+processing systems as needed.
+At the very least, the ability to originate
+requisitions can be distributed to anyone with access to a mail system
+that can originate a proper requisition form.
+
+As a last example,
+\MH/ already supports group discussions with its BBoard facilities
+which allow for automatic sorting of mail by group address,
+with shared private or public group access to contributed items.
+As has been shown to be possible with administrative record systems,
+there is no obvious limit to the ways that group discussion traffic
+might be organized into structured collections with indices,
+annotations, or reference pointers
+to aid in making conference archives more useful.
+Indeed, \MH/ tools could even be used to feed discussion items into
+existing conference systems.
+
+\section{Distributed Mail}                     % mtr
+Next, we consider how \MH/ might be used in a distributed mail environment.
+Two schemes are discussed:
+one in which connectivity is high and connections are relatively ``cheap'',
+and one in which connectivity is low and connections are ``expensive''.
+
+\subsection{The ARPA Internet Environs}                % mtr
+The ARPA Internet community consists of many types of heterogeneous nodes.
+Some hosts are large mainframe computers,
+others are personal workstations.
+All communicate using the \milstd/ TCP/IP protocol suite\cite{IP,TCP}.
+Messages which conform to the Standard for the Format of ARPA Internet Text
+Messages\cite{DCroc82}
+are exchanged using the Simple Mail Transfer Protocol\cite{SMTP}.
+
+On smaller nodes in the ARPA Internet it is often impractical to maintain
+a message transport agent.
+For example,
+a workstation may not have sufficient resources (cycles, disk space)
+in order to permit an SMTP server and associated local mail delivery system
+to be kept resident and continuously running.
+Furthermore,
+the workstation could be off-net for extended periods of time.
+Similarly,
+it may be expensive (or impossible) to keep a personal computer
+interconnected to an IP-style network for long periods of time.
+In other words,
+the node is lacking the resource known as ``connectivity''.
+
+Despite this,
+it is often desirable to be able to process mail with \MH/ on these smaller
+nodes,
+and they often support a user agent to aid the tasks of mail handling.
+To solve this problem,
+a network node which can support a message transport entity
+(known as {\it service} host) offers
+a maildrop service to these less endowed nodes
+(known as {\it client} hosts).
+The Post Office Protocol\cite{JReyn84} (POP) is intended to permit a
+workstation to dynamically access a maildrop on a service host to pick-up
+mail.%
+\nfootnote{Actually,
+there are three different descriptions of the POP.
+The first, cited in \cite{JReyn84},
+was the original description of the protocol,
+which suffered from certain problems.
+Since then,
+two alternate descriptions have been developed.
+The official revision of the POP\cite{MButl85},
+and the revision of the POP which \MH/ uses
+(which is documented in an internal memorandum in the \MH/ release).
+This paper considers the POP in the context of the \MH/ release.}
+The level of access includes the ability to
+determine the number of messages in the maildrop and the size of each message,
+as well as to retrieve and delete individual messages.
+More sophisticated implementations of the POP server
+are able to distinguish between the header and body portion of each message,
+and send $n$ lines of a message to the POP client.
+This capability is useful in thinly connected environments where conservation
+of bandwidth is important.
+By utilizing a more intelligent POP client,
+a user may generate ``scan~listings'' and dynamically decide which messages
+are worth taking delivery on.
+The philosophy of the POP is to put intelligence in the
+POP clients and not the POP servers.
+
+The underlying paradigm in which the POP functions is that of a
+split-slot/remote-\UA/ model.
+The client host (such as a workstation) is without a co-resident
+{\it message transport agent} (\MTA/),
+and thus makes use of a service host with an \MTA/ to obtain posting (SMTP)
+and delivery (POP) services.
+The entity which supports this type of environment is called a remote-\UA/
+since the user agent resides on a different host than its associated message
+transport agent.
+
+One very important issue which must be raised at this point is one of
+authentication.
+The POP requires that a client identify itself to the server using a
+server-specific user-id and a server/user-specific password.
+This authentication is required to prevent unauthorized entities from
+accessing a maildrop on a POP service host.
+It must be emphasized that the POP client is not a ``trusted'' entity of the
+\MTS/ in any sense at all.
+
+Ideally,
+one would also like to authenticate mail as it is posted on the POP service
+host using the SMTP.
+Currently,
+in the ARPA Internet community,
+no authentication is done with SMTP transactions.
+This is considered a shortcoming by those interested in researching the
+split-\UA/ model of distributed mail.
+The MZnet environment,
+discussed in the next section,
+has authentication facilities for posting mail.
+
+The current release of \MH/ supports the above model fully:
+a POP client program is available to retrieve a maildrop on a POP service
+host.
+In addition,
+using the SMTP configuration for delivery in \MH/,
+a user is able to specify a search-list of service hosts (and networks)
+with which to try to post mail.
+Using this search-list,
+when an \MH/ user posts a draft,
+the \pgm{post} program will attempt to establish an SMTP connection
+with each host in the list to post the message until it succeeds.
+Initial experimentation with the split-\UA/
+in a local network environment has proved quite successful.
+
+\subsection{The MZnet Environs}                        % jns
+In 1983,
+the MZnet project\cite{EStef84} at the University of California, Irvine
+set out to study the problems involved with bringing
+Internet-class mail handling facilities to personal computers.
+The project used Apple~II computers running the CP/M 2.2 operating system.
+Programming was done in a subset of the C language called BDS C.
+The transport system was based on the \MMDF/ PhoneNet software,
+and implemented a {\it split-slot} arrangement between a personal computer
+and a larger,
+centralized mail distribution system that performed user
+authentication and provided a relatively secure mail transfer channel.
+The user agent, CP/MH, was based on \MH/.
+
+A conclusion of the experiment was that small personal computer systems
+with dial-up phone connections constrain user agent systems design in
+ways that require use of a {\it split-slot} interface between the \UA/
+and its supporting \MTA/, and that this interface
+best provides the required services if it has error controlled command
+and data transfer facilities, with interactive behavior. 
+Another conclusion indicated that a good design for a user agent in such
+a small personal computer
+environment could be based on a very modular architecture,
+such as \MH/.
+A final conclusion was that session-level authentication of the client \UA/
+is required for both posting and delivery.
+
+It should be noted that the MZnet project had a profound influence on the
+development of the POP used by \MH/.
+A somewhat more detailed discussion of the relations between the two
+environments can be found in the POP description contained
+in the \MH/ release.
+
+\section{A Final Note}                         % jns
+With the fifth major release of the \MH/ system,
+it has become clear that most major increases in functionality can come
+only at the expense of either efficiency or portability.
+Although there has been great effort to keep \MH/ portable to a number of
+\unix/ implementations,%
+\nfootnote{As of this writing,
+there are approximately 75~sites running \mh5
+on five different implementations of \unix/.}
+the divergence in process management facilities,
+file system enhancements,
+and even C~compiler capabilities
+has already presented obstacles to some attempts to rehost the \MH/ code.
+
+There has been some discussion of implementing specialized \MH/ daemons
+that maintain context information over one or more sessions,
+thus decreasing the amount of overhead involved in starting each \MH/ command.
+Unfortunately,
+even if such daemons were to be implemented,
+they would be very difficult to move to versions of \unix/
+without sophisticated process management facilities,
+and even then the differences in ``philosophies''
+of process management\cite{WJoy83,EOlse84}
+would tend to keep such daemons system specific.
+A better solution seems to be simply to tune existing code.

+Traditional computer mail systems involve a co-resident User Agent (UA)
+and Mail Transfer System (MTS) on a time-shared host computer 
+which may be connected to other hosts in a network,
+with new mail posted or delivered directly through 
+co-resident mail-slot programs.
+To introduce personal micro-computers (PCs) into this environment 
+requires modification of the traditional mail system architecture.
+To this end, the MZnet project uses a {\it split-slot} model,
+placing UA programs on the PCs while leaving MTA programs
+on a mail relay host which can provide authentication and buffering.
+The split-slot arrangement might be viewed as a new protocol level which 
+operates somewhere between the currently defined MTS-MTS and UA-UA levels.

+\section*     {Introduction}
+Mail systems were born and have grown up on large central
+time sharing systems,
+often imbedded in large networks of inter-operating computers with 
+a set of distributed processes automatically transferring mail
+between users.  
+This is certainly the case with the U.S. Department of Defense (DoD) 
+Advanced Research Projects Agency Network (ARPANET)
+\cite{ARPANET-Literature}
+where much of the original computer network mail systems 
+research and development has taken place.  
+Other mail networks such as the Computer Science Network
+\cite{CACM-83}
+sponsored by the U.S. National Science Foundation,
+have also used relatively large shared computers 
+lodged in an institutional setting,
+though they are often connected together with ordinary dial-up
+telephone links to form a large geographic network.    
+Another U.S. example is USENET
+\cite{USENET-Literature}
+which connects thousands of Unix\footnote{UNIX is
+a Trademark of Bell Laboratories, Inc.}
+systems together with informally-supported dial telephone links.
+Although there have been several attempts, there appear to be no 
+successful mail networks based on small personal computers, 
+such as those that use the CP/M\footnote{CP/M is a
+Trademark of Digital Research, Inc.}
+or MS-DOS\footnote{MS-DOS is a Trademark of Microsoft Corporation.}
+operating systems.  
+
+\tagfigure{figure1}{The MHS Model}{mhsmodel}
+The accepted architectural model (see Figure~\ref{mhsmodel})
+for computer network mail
+(first articulated by the IFIP 6.5 Systems Environment Working Group) 
+involves a User Agent (UA) which posts new mail items through a mail slot
+\cite{Vittal81,Deutsch81,Pickens81,Kerr81}
+to a Mail Transfer Agent (MTA) which delivers posted items 
+to designated UA recipients through corresponding delivery slots.  
+When mail is to be delivered to a UA on another host, it is transferred
+first to another MTA on the recipient user's host, which in turn puts
+the mail item through its local delivery slot.  
+In this model, a Mail Transfer System (MTS) may be viewed 
+as a collection of MTAs with network connections among them 
+to provide Mail Transfer Services for a large number of users on 
+different host computers.
+
+Replicating this UA/MTA/MTS model on a personal micro-computer (PC)
+is not an easy task.
+Aspects of PCs that make support of this model difficult include
+limited storage capacities,
+limited processing capabilities,
+and the fact that PCs are geared to support a single user
+rather than several users at once.
+A PC with limited secondary diskette storage and 
+limited processing capacity (often single-thread) is not well suited 
+to support the full range of automatic interactions between a UA and 
+an MTA, or the necessary interactions between MTAs in an MTS. 
+For example,
+we do not see any way to certify PC systems for authentication 
+of posted mail.  
+A PC can change its entire character and behavior with insertion of a new 
+program diskette, suggesting that it is the operating system 
+diskettes and their users that must be certified, rather than the computers.  
+Review of certification issues shows that it is not the computer, 
+but its operators and managers that must be certified, 
+and this involves the notions of central management and control.  
+All this is lost in the maze of PCs that we see proliferating 
+on and off our campuses, in and out of our offices and homes.  
+
+Thus, we see a need for a new arrangement with the UA separated from 
+its MTA, and using communication protocols to interact with it in ways 
+that resemble MTA-to-MTA interactions.
+The UA is placed on the PC end, while the more complex
+tasks performed by the MTA are relegated to the remote host end.
+The remote MTA must authenticate mail items offered by the PC-based 
+UA, just as it would for a co-located UA, but the task is more difficult 
+because the PC UA is potentially anyone among the public telephone 
+connectable population.  
+This can be handled with password systems, but recognition and 
+identification are not the only services to be provided at the posting slot.  
+Posting also requires some validation of recipient addresses, 
+and validation of the syntax and semantics of certain header fields.
+Example standards are provided by the U.S. National Bureau of Standards 
+(NBS) and the U.S. DoD ARPANET for the format of mail to be transferred
+\cite{RFC-822,NBS,CCITT}.
+
+The new arrangement described in this paper might be called a
+{\it split mail slot} in that the UA side of the slot is split away from 
+the MTA side.  
+Although the UA and MTA may be on opposite ends of a telephone connection, 
+they must still act together as a single processing unit 
+to move mail from one to the other, with all that this may entail.  
+This gives rise to a number of new MTA/UA requirements such as error 
+control for service requests, user intervention to select items for 
+delivery, and user postponement or rejection of delivery without 
+triggering failure notices to senders.  
+These are not serious problems when both MTA and UA are 
+programs running on a single host.  
+For example, with both UA and MTA on the same host, 
+unwanted junk mail is simply deleted at low cost, 
+compared to the cost of deletion after a long delivery transmission time.  
+Better that our PC users be able to discard items 
+without delivery transmission.  
+
+\subsection*  {Overview of the MZnet Environment}
+The MZnet project is an undergraduate student effort sponsored within 
+the Information and Computer Science (ICS) Department of the 
+University of California at Irvine (UCI) in Southern California.  
+For the past 2 years, the UCI mail network, known as
+ZOTnet, has been connected into the Computer Science 
+Network (CSnet) and in 1984, has joined the DoD ARPA Internet with a 
+{\it Split-Gateway} connection \cite{Rose84}
+to the University of Southern California 
+Information Sciences Institute (USC-ISI).  
+The MZnet split-slot arrangement may have some similarities to the 
+Split-Slot Internet Gateway
+at least in name, 
+but the problems and the implementations are quite different.  
+
+The UCI ZOTnet environment \cite{Rose83-1}
+gives the MZnet project a full-fledged
+Internet-class mail system as its foundation.  
+The MZnet project objective is to extend this class 
+of mail service to personal computers located in student and faculty 
+residences, offices and laboratories, without waiting for full-blown 
+local area networking to first provide connections.  
+This follows a pattern of making the most of existing facilities 
+to provide a reasonable level of service.
+
+The UCI ZOTnet uses the CSnet-provided MMDF
+(Multi-channel Memo Distribution Facility) software \cite{MMDF}
+from the University of Delaware to interconnect 
+two VAX 750 Unix systems with two DEC TOPS-20 systems 
+through a port selector, with dial telephone connection to a CSnet relay
+\cite{CSNET-UCI}.
+The ZOTnet has since evolved into an ethernet-connected 
+local area network with the aforementioned
+gateway connection into the DoD Internet.
+The ZOTnet also connects to USENET with the UUCP protocols,
+and provides format transformations for mail flowing between 
+protocol domains
+\cite{Rose83-2,RFC-MMM}.
+Adding to the reach of the ZOTnet with MZnet 
+is a natural part of its evolution\footnote{For those who are
+properly curious about such things, 
+the name ``ZOTnet'' derives from the cry of the UCI mascot which 
+is the Anteater from the B.C. comic strip, and MZnet is simply 
+a contraction for Micro-ZOTnet.}.
+
+To this point we have set the context of the MZnet project.
+The remainder of this paper is devoted to relatively technical 
+discussions of implementation of the PC user agent programs 
+and the split-slot UA/MTA interface. 
+
+\section*     {The MZnet User Agent: CP/MH}
+CP/MH is a collection of programs designed to work in conjunction
+with the Micro ZOTnet (MZnet) as an extension of the UCI ZOTnet.
+CP/MH programs permit a user of a CP/M 2.2-based microcomputer to
+send and receive ZOTnet mail messages, as well as to manipulate
+them locally on floppy disks.  
+The CP/MH programs are written in the C programming language and 
+should be portable to similar operating environments, such as MS-DOS, etc.
+
+CP/MH is based on the UCI version of the Rand MH message handling system
+\cite{MH}
+for the Unix operating system.  
+The major philosophical differences between CP/MH and typical user agents
+such as MSG
+\cite{Vittal81}
+and its descendants are those of modularity and of user interface.  
+In CP/MH (as in MH) the user does not invoke a single monolithic program 
+to deal with mail, but rather invokes individual, 
+non-interactive programs with common knowledge
+of the way messages are stored.  
+Each program has default behavior which can be modified by using Unix-style 
+command line options at time of invocation or through a user profile.  
+Help messages can also be evoked from CP/MH programs.
+
+\subsection*  {Messages and Folders}
+The format of a CP/MH message adheres more or less to the syntax
+described in RFC 822
+in which a message consists of headers containing information pertaining 
+to the message source and destination, 
+and the message body, separated from the headers by a blank line.  
+An example of such a message might be:
+
+\begin{verbatim}
+     Date: 02 Nov 83 23:04:53 PST (Wed) 
+     To: Toto <address@hidden>
+     From: The Great And Powerful Oz <address@hidden>
+     Subject: What Be Your Excuse?
+
+     What's the matter?  I ask you for a simple thing like
+     "distribute this to address@hidden," and you can't do it.
+     You undergrads will do anything to get out of work!
+
+     --ozzie
+\end{verbatim}
+
+Following the MH convention, each message is kept in a separate file.  
+Since a message is simply ASCII text, it can be operated upon by 
+non-CP/MH programs (such as text editors, in particular).
+
+Collections of messages are called {\it folders}.  Under CP/MH,
+folders are represented by several files: an {\it info} file,
+containing maintenance information about the folder, and a set
+of message files with the same name as the info file, but with
+unique numeric suffixes ({\it extensions} in CP/M parlance).  
+An example of this naming scheme might be:
+
+{\tt
+\begin{description}
+\item[{\tt DRAFT}]     {\rm the info file for the {\tt DRAFT} folder}
+\item[{\tt DRAFT.001}]  {\rm message 1 in the folder}
+\item[{\tt DRAFT.002}]  {\rm message 2 in the folder}
+\item[{\tt DRAFT.003}]  {\rm message 3 in the folder}
+\end{description}
+}
+
+The number of messages that may be stored in a folder is limited
+primarily by the storage capacity of a floppy disk, but also by
+the three-digit limit of a CP/M extension.  
+
+The info file contains a field named {\tt CURRENT:} specifying the
+current message number.  
+The current message number signifies the default message operated upon 
+by CP/MH commands using a particular folder.  
+The current message number may be modified by some commands.  
+An example of the contents of the info file {\tt DRAFT} might be
+
+\begin{flushleft}
+\hspace{.5in} {\tt CURRENT: 3}
+\end{flushleft}
+
+This indicates that the file {\tt DRAFT.003} would be operated upon
+when default conditions apply (i.e. when no message number is
+explicitly given to a CP/MH command).
+
+Possible future uses for the info file include named message sequences
+(a set of messages to which commands may be applied as a whole) and
+user profile information for application to particular folders (there
+is presently a single user profile, described shortly).
+
+A floppy diskette may contain more than one folder, but folders
+do not extend over more than one floppy diskette; therefore two
+different diskettes may contain folders with the same name.
+
+\subsection*  {CP/MH Commands}
+Commands operating on messages can be divided into several general categories:
+\medskip
+\begin{description}
+\item[Transporting:]   sending, receiving
+\item[Viewing:]                selecting for display, showing header summaries
+\item[Creating:]       composing, replying, forwarding
+\item[Archiving:]      categorizing, refiling, deleting, sorting
+\end{description}
+
+\medskip
+The architecture of CP/MH permits the simulation of some of these
+categories using standard CP/M commands when CP/MH, in its present
+primitive state, does not cover them.
+
+A minimal functionality is presently provided by the following four commands:
+\medskip
+\begin{description}
+\item[COMP]
+composes mail items:
+creates a file containing header information taken 
+from a standard or user-specified template.  
+This newly-created file may be edited to fill in
+the header fields and body.
+\item[REPL]
+replies to mail items:
+creates a file containing header
+information appropriate for answering a given mail item.
+This newly-created file may be edited to
+change header fields and fill in the body.
+\item[SEND]
+sends mail items:
+posts selected items through the split-slot from a draft folder.
+\item[INC]
+receives mail items:
+takes delivery of selected items
+across the split-slot, incorporating
+them into a mailbox folder.
+\end{description}
+\medskip
+These commands, with a few enhancements and modifications
+appropriate to the CP/M environment, are functionally almost
+identical to their Unix MH counterparts.
+
+CP/MH commands are invoked like any other 
+CP/M commands such as ED, PIP, or DIR.  
+Command line options are generally preceded by a dash 
+(e.g. {\tt -editor A:ED}), and may be abbreviated.  
+Folder names are preceded by a plus (e.g. {\tt +B:DRAFT}).
+Messages are identified by numbers or by the special names {\tt first},
+{\tt last}, {\tt current}, {\tt next}, and {\tt previous}.
+
+An example of use of a CP/MH command is:  
+
+\begin{flushleft}
+\hspace{1in} {\tt comp -edit a:ed -use last +b:draft -log}
+\end{flushleft}
+
+This particular example will edit the last-composed message (the
+{\tt -use last} option) in the folder {\tt DRAFT} on disk drive {\tt B:}
+(the {\tt +b:draft} option), using the standard CP/M editor ED on disk
+drive {\tt A:} (the {\tt -edit a:ed} option), and prompting the user when
+it is appropriate to change disks (the {\tt -log} option).
+
+All CP/MH commands have a {\tt -help} option which displays all
+available options for the particular command invoked.
+Another common option is {\tt -log} which permits the user to change
+({\it relog}) diskettes after invoking a command, for purposes of
+selecting diskettes with message folders or with editor programs.
+This is particularly useful on single-drive systems or on systems
+with diskettes of low storage capacity.
+
+\subsection*  {The Profile}
+If there are options commonly used with a particular CP/MH command, 
+they may be entered in the user profile contained in the file called 
+(naturally enough) {\tt PROFILE}, which must exist on the same diskette on 
+which CP/MH commands reside and from which the commands are invoked.  
+A profile entry consists of a program name followed by a colon and 
+the options to be used with that program, for example:
+
+{\tt
+\begin{flushleft}
+\hspace{1in} comp: -editor A:VEDIT +B:outbox -log \\
+\hspace{1in} repl: -editor A:VEDIT -log \\
+\hspace{1in} send: +B:outbox \\
+\hspace{1in} inc: +B:inbox -log
+\end{flushleft}
+}
+
+Individual profile components are overridden by options given at
+the time of invocation (e.g. {\tt -noedit} given on the command line
+will override the {\tt -editor} profile component for a particular command).
+
+\section*     {The MZnet Split-Slot Mail Transfer System}
+The MZnet split-slot software implements a peer-to-peer
+communication protocol between a time-sharing host's MTA and a personal 
+micro-computer (PC) UA.
+This MZnet protocol extends the UA/MTA/UA model of
+computer-based message systems (CBMS) to provide a
+split gateway function between individual PCs and the ZOTnet
+similar to the UCI ICS split Internet gateway described previously
+(see Figure~\ref{splitslot}).
+\tagfigure{figure2}{The Split-Slot Model}{splitslot}
+
+\subsection*  {The Structure of the Split-Slot}
+The MZnet Split Gateway consists of three distributed processing components: 
+\medskip
+\begin{itemize}
+\item A PC running a UA (in MZnet, CP/MH) acting as the mail server.
+\item A mini/mainframe host running a full MTA (MMDF in MZnet)
+providing mail relay services.
+\item A communication protocol (a modified version of MMDF PhoneNet) to
+connect the two ends of the split-slot.
+\end{itemize}
+\medskip
+Although this combination may not be unique, the method by which the MZnet 
+split-slot bonds these parts together uniquely deals with the 
+problems of remote user agents.
+In addition to overcoming limited storage and processing capacities,  
+remote user agents must deal with noisy modem lines, 
+mail software certification, and mail system security problems.  
+The MZnet architecture appears to solve these problems with
+a clean mail interface for PCs.
+
+\subsection*  {The MZnet Mail Server}
+The split-slot mail server consists of a set of {\it command packet}
+programs run from the PC.
+These programs simply present commands
+through the PhoneNet communication protocol to the mail relay slave program
+on the host.
+Some basic commands are:
+
+\medskip
+\begin{description}
+\item[PostMail]                posts mail drafts to MTA
+\item[GetMail]         accepts mail from MTA
+\item[RemoteScan]      displays information about waiting mail
+\item[Quit]            drops connection between PC and Host
+\end{description}
+
+\medskip
+Each command has the form:
+
+\begin{flushleft}
+\hspace{.5in} Command Request \\
+\hspace{.5in} Data Transmission \\
+\hspace{.5in} Command Termination
+\end{flushleft}
+
+For example, the PostMail command is a small program that:
+\medskip
+\begin{itemize}
+\item initiates a command with the Mail Slave by sending the command
+name (PostMail) encoded within a PhoneNet packet;
+\item sends a series of PhoneNet packets that contain pieces of
+the mail item to be posted; 
+\item finally sends a command termination signal to end
+the transaction without
+terminating the connection between host and PC.
+\end{itemize}
+
+\subsection*  {The MZnet Channel To MMDF}
+The MZnet Channel runs on the MTA host under the University of Delaware's
+MMDF (Version 1) and is responsible for both delivery of received mail
+to MZnet users, and posting of MZnet user-originated mail.
+The MMDF MZnet channel maintains a unique message queue for each
+registered MZnet user.
+As new mail items arrive,
+they are posted to the appropriate queues,
+where MZnet holds the mail items for pickup by their registered
+recipients.
+
+To send or receive mail,
+the MZnet user must attach to the host,
+log into the public MZnet account,
+and identify (authenticate) himself.
+During the MZnet session with the host,
+the user has access only to that restricted set of functions
+provided by the MZnet split gateway protocol:
+he may request delivery of queued mail with GetMail,
+or post new mail with PostMail.
+Prior to taking delivery of queued mail,
+a survey of waiting mail also may be requested with RemoteScan to obtain
+message size information (among other data)
+to allow intelligent disposition 
+of mail in the queue.
+
+Hidden within these activities are issues of security and certification.
+To certify and establish the identity of the user,
+a second password is requested after logging into the 
+public MZnet account.
+This certification procedure allows MZnet to certify the source
+of originated mail.
+A relatively secure environment is provided by MZnet,
+as it is the only interface to the host permitted to MZnet users
+(once beyond the public login procedure),
+and it offers only the severely restricted set of
+PhoneNet-encoded commands.
+Aside from security issues,
+using a single account to handle all MZnet users
+reduces demands on system resources.
+
+\subsection*  {The MZnet-PhoneNet Protocol}
+A unique facet of the MZnet system derives from the PhoneNet File 
+Transfer Protocol (FTP).
+PhoneNet FTP is a simple error-checked packet protocol which transfers
+ASCII plaintext.
+PhoneNet encodes any non-plaintext character (or any other character
+``forbidden'' by the idiosyncrasies of the communicating systems) by
+mapping it onto an ``accepted'' character set.
+The accepted character set mapping is determined by
+a ``negotiating'' session between the two systems at the start of
+the PhoneNet session.
+
+MZnet transfers all information (both commands and data) in PhoneNet
+packets to obtain error control.
+The MZnet-PhoneNet command FTP tolerates noise with a high degree
+of success, and in effect, connects both ends of the Split Slot
+together with a reliable set of virtual wires.
+
+\subsection*  {MZnet Session Example}
+Here, a typical MZnet session is presented, with the UA commands
+issued from the PC side of the connection printed
+in a {\tt typewriter} typeface, and the responses
+from the host side printed
+in an {\it italic} typeface.
+PhoneNet interactions are indented.
+The initial connection to the host is accomplished with the
+{\tt term} program, which provides a simple terminal emulation
+function.
+The prompt of the PC for a UA command is ``A$\rangle$''.
+Note that passwords are never echoed by the host system.
+
+\begin{tabbing}
+xxxxxxxx \= xxxxxxx \= \kill
+\> A$\rangle$ {\tt term} \\
+\> {\it login:} {\tt mznet} \\
+\> {\it password:} \\
+\> {\it MZ-Password:} \\
+\> \> PhoneNet packet negotiation \\
+\> {\it Connected.} \\
+\> \> exit terminal mode \\
+\> A$\rangle$ {\tt send cur} \\
+\> \> PostMail command \\
+\> \> message text packet transmission \\
+\> \> command terminator \\
+\> A$\rangle$ {\tt quit} \\
+\> \> Quit command \\
+\> {\it Disconnecting.}
+\end{tabbing}
+
+\section*     {Conclusions}
+The main conclusions of this paper are that 
+small personal computer systems 
+with dial-up phone connections constrain User Agent systems design
+in ways that require use of a {\it split-slot} interface between
+the UA and its supporting Mail Transfer Agent (MTA), and that
+this interface will best provide the required services if it
+has error controlled command and data transfer facilities, with 
+interactive behavior.
+
+It is also believed that a good design for the small PC UA
+is based on a very modular architecture, such as the Rand MH
+system, which has been used as a pattern for the MZnet UA.
+
+By bringing these concepts together,
+we expect MZnet to provide reliable UA/MTA
+service to a distributed set of small personal computers, to match
+the quality of service that is normally only available from larger
+mainframe host systems with co-resident UA/MTA pairs.

+\appendix{A}{MH Commands}
+\MH/ is composed of several \unix/ programs,
+which in theory are fairly simple and single-purposed.
+These commands are functionally grouped below:
+
+\psect{Composing Mail}
+\pitem{comp} compose a message.
+A program to originate a message.
+Usually, a special prompting editor front-end, \pgm{prompter},
+is used to fill-in a composition template with the addressees of
+the message, subject, and so forth.
+
+\pitem{dist} redistribute a message to additional addresses.
+A program that re-enters a message previously received by the user
+into the message transport system.
+Only new addresses are added;
+the body of the message is not changed in any way.
+
+\pitem{forw} forward messages.
+A program that encapsulates one or more messages in a new message draft.
+In addition, the user may add initial and/or closing comments.
+
+\pitem{repl} reply to a message.
+A program that constructs a reply to a message using a reply template.
+The template mechanism has sufficient generality to permit the user to
+``program'' the form of the reply draft based on the contents of the message
+being replied-to.
+
+\pitem{send} send a message.
+A program that posts a draft with the message transport system.
+The \pgm{send} program is
+usually invoked by one of the four preceding programs,
+and performs simple front-end pre-processing prior to invoking the
+\pgm{post} program.
+For example,
+if invoked in {\it push}'d mode,
+\pgm{send} will immediately relinquish control of the user's terminal and
+post the message in the background.
+If the posting fails,
+\pgm{send} will send back a failure notice to the user.
+If the user had \pgm{push\/}'d the sending of the draft,
+then by default
+the draft being sent is encapsulated in the failure notice.
+This permits easy \pgm{burst}'ing of the failure notice to retrieve the
+original draft.
+Otherwise,
+if the posting was successful,
+the draft is marked as having been sent.
+
+\pitem{whatnow} prompting front-end for send.
+A program which is called by  \pgm{comp}, et. al.,
+after the initial draft has been generated.
+The \MH/ user can specify a different \pgm{whatnow} program,
+which yields considerable extensibility.
+
+\pitem{whom} report to whom a message would go.
+A program which examines the addresses of the draft and expands
+all user-defined aliases contained therein.
+Optionally,
+\pgm{whom} may actually interact with the message transport system
+to determine the validity of the final addresses.
+This program is also usually invoked by \pgm{comp}, et.~al.
+
+\psect{Posting Mail}
+\pitem{ali} list mail aliases.
+A simple front-end to the \MH/ aliasing mechanism.
+
+\pitem{ap} parse addresses 822--style.
+A useful debugging tool for PostMasters who wish to examine how \MH/
+interprets an Internet address.
+
+\pitem{conflict} search for alias/password conflicts.
+Another program used by system administrators to check the consistency of
+\MH/ alias files, and portions of the local message transport agent.
+
+\pitem{install-mh} initialize the MH environment.
+A program which is automatically executed the first time a user issues an
+\MH/ command.
+This program performs once-only initialization of the user's \MH/ environment.
+
+\pitem{mhmail} send or read mail.
+A simple program generally used by other programs to generate messages.
+The \pgm{mhmail} command is similar in purpose to the old \pgm{BellMail}
+program.
+
+\pitem{post} deliver a message.
+A complex \MH/ back-end that interacts with the local message transport agent
+to enter messages through the posting slot.
+(See the description of \pgm{send} above).
+
+\psect{Reading Mail}
+\pitem{inc} incorporate new mail.
+A program that interacts with the local message transport agent
+to retrieve messages from the user's maildrop.
+
+\pitem{msgchk} check for waiting mail.
+A program which reports the status of mail waiting in the user's maildrop.
+
+\pitem{show} show (list) messages.
+A program which lists messages to its standard output
+(usually the user's terminal),
+possibly invoking another program to do the actual listing.
+Most users of \MH/ have \pgm{show} automatically call the \pgm{mhl} program
+to format the message.
+The \pgm{next} and \pgm{prev} programs are simply
+\eg{show\ next} and \eg{show\ prev},
+respectively.
+
+\pitem{mhl} produce formatted listings of MH messages.
+A program which displays a message as directed by a template.
+This permits the user to filter out uninteresting headers
+and re-arrange other headers to a particular preference.
+In addition to being invoked by \pgm{show},
+the \pgm{mhl} program is optionally also
+invoked by \pgm{forw} to format each message being forwarded;
+invoked by \pgm{repl} to format the body of a message being replied-to,
+if that message is being included in the reply draft;
+and,
+invoked by \pgm{post} to format a message being sent as a blind-carbon-copy.
+
+\pitem{rmm} remove messages.
+A program that removes messages from an \MH/ folder,
+optionally running a user-defined program instead of deleting them.
+If no program is given,
+the messages are ``softly'' removed,
+so they may possibly be recovered later.
+
+\pitem{scan} produce a one-line-per-message scan listing.
+A program that generates a scan listing for messages.
+Each line of the listing contains date, source, subject,
+and possibly the initial body of the message.
+
+\psect{Folder Handling}
+\pitem{folder} set/list current folder/message.
+A program used to list information concerning the current folder,
+or set the current folder and/or message.
+
+\pitem{folders} list all folders.
+A program to list information on all folders
+(actually, just a special case of the \pgm{folder} command).
+Since the \MH/ folder structure may be recursive,
+the user can indicate that \pgm{folders} should recursively examine all
+folders.
+
+\pitem{refile} file message(s) in (an)other folder(s).
+A program to move (or copy) messages from a source folder to one or more
+destination folders.
+
+\pitem{rmf} remove folder.
+A program that deletes a folder and all messages therein.
+
+\psect{Message Selection}
+\pitem{anno} annotate messages.
+A program to arbitrarily annotate messages.
+If the user so desires,
+after distributing, forwarding, or replying-to a message,
+\MH/ will automatically attach an annotation to the
+original message indicating the date and addresses.
+
+\pitem{mark} mark messages.
+A program to manipulate user-defined sequences (lists of messages).
+Usually, \pgm{mark} is not employed directly by the \MH/ user.
+
+\pitem{pick} select messages by content.
+A program to examine a list of messages and choose those which meet a
+particular selection criterion.
+The \pgm{pick} program is often used in \unix/ back-quoted operations to pass
+message sequences to other \MH/ commands.
+
+\pitem{sortm} sort messages.
+A program to sort a list of messages according to the date given in a
+particular field.
+
+\psect{Distribution List Handling}
+\pitem{bbc} check on BBoards.
+A front-end to run \pgm{msh} on a list of distribution lists which the
+user isn't current on.
+
+\pitem{bbl} manage a BBoard.
+A (depreciated) program used to manually manage the local archives of a
+distribution list.
+These functions (archiving, expunging) are performed automatically by \MH/.
+
+\pitem{burst} explode digests into messages.
+A program used to decapsulate messages from ARPA Internet digests.
+In addition,
+messages which have been encapsulated during forwarding
+(i.e., with \pgm{forw\/})
+can also be decapsulated using \pgm{burst}.%
+\nfootnote{Similarly, blind-carbon-copies may be decapsulated,
+though only socially mature users should do so.}
+
+\pitem{msh} MH shell (and BBoard reader).
+A monolithic program used to implement \MH/ commands on
+messages arranged in a single file (maildrop format).
+Useful
+since distribution lists are kept in this format to minimize consumption of
+system resources.
+
+\pitem{pack} compress a folder into a single file.
+A program which takes messages stored in \MH/ format and places them in a
+single file (using the same format known by \pgm{msh\/}).
+
+\psect{Interface to the \unix/ File System}
+\pitem{mhpath} print full pathnames of \MH/ messages and folders.
+A program which maps \MH/-style names into the \unix/ file naming convention.

+\appendix{B}{Distribution Mechanics}
+The \mh5 distribution is available in two forms:
+\smallskip
+{\advance\leftskip by\parindent
+\item{1.} Anonymous FTP\hbreak
+If you can FTP to the ARPA Internet,
+use anonymous FTP to the ARPAnet host UDel-Huey [10.2.0.96]
+and retrieve the file portal/mh.5--tar.
+This is a \pgm{tar} image of size 2.1~MB (approximately).
+
+\item{2.} 9--track tape, 1600~bpi, \pgm{tar} format\hbreak
+Otherwise, you can send \$50.00 to the address below.
+This covers the cost of a magtape, handling, and shipping.
+In addition,
+you'll get a laser-printed hard-copy of the \MH/ documentation.
+The documentation includes installation guide,
+\MH/ Tutorial,
+\MH/ User's Manual,
+changes document (from \mh4 to \mh5),
+and BBoards Manual.
+
+\item{} If you go with this option,
+be sure to include your USPS address with your check.
+Checks should be made payable to
+$$\hbox{Regents of the University of California}$$
+It's also a good idea (though not mandatory) to send a computer mail message
+to {\tx address@hidden when you send your check via USPS to ensure minimal
+turn-around time.
+The distribution address is:
+$$\displayindent=\leftskip     \advance\displayindent by1.5\parindent
+    \halign{\leftline{#}\cr
+       Support Group\cr
+       Attn: MH Distribution\cr
+       Department of Information and Computer Science\cr
+       University of California, Irvine\cr
+       Irvine, CA  92717\cr
+       \cr
+       714/856--6852\cr
+}$$
+
+\item{} Sadly, if you just want the hard-copies of the documentation,
+you still have to pay the \$50.00.
+The \pgm{tar} image has the documentation source
+(the man is in \ROFF/ format, but the rest are in \TeX\ format).
+\smallskip}
+\noindent
+In addition,
+there is some hope that \mh5, or a successor,
+might be found in a future 4.x~Berkeley distribution.
+
+Although \MH/ is not ``supported'' per se,
+it does have a bug reporting address.
+Normally,
+the address {\tx address@hidden is used to report bugs and bug fixes.
+There are however, 
+two discussion groups which concern themselves with \MH/:
+\smallskip
+{\advance\leftskip by\parindent
+\item{1.} address@hidden
+A discussion group for the \MH/ user community at large.
+Appropriate topics include:
+questions about how to use \MH/,
+tips on \MH/ usage,
+and exchange of \MH/ shell scripts.
+All requests to be added to or deleted from this list,
+along with problems,  questions and suggestions,
+should be sent to {\tx address@hidden
+
+\item{2.} address@hidden
+A discussion group for \MH/ maintainers and experts.
+Appropriate topics include:
+questions on how to configure \MH/,
+tips on \MH/ configuration,
+exchange of \MH/ bug reports (and fixes).
+All requests to be added to or deleted from this list,
+along with problems, questions and suggestions,
+should be sent to {\tx address@hidden
+\smallskip}
+\noindent
+The \eg{UCI} host is also known as \eg{ucivax},
+so a possible \UUCP/ path might be {\tx $\tdots$!ucbvax!ucivax!bug-mh}.
+
+Updates to \MH/ are published on the {\tx MH-Workers} list
+in the form of context diffs,
+and the appropriate distribution images are updated as well.

+{\rightskip=0pt\narrower
+\lp
+The UCI version of the Rand Message Handling System (\MH/) is discussed.
+\MH/ is a powerful user agent which operates in the ARPA Internet and UUCP
+environments.
+In addition to the usual functions provided by similar programs,
+\MH/ has several distinguishing characteristics which give the user
+additional message handling capability.
+In particular,
+\MH/ provides mechanisms for maintaining an organized mail environment,
+tailoring its behavior,
+and extending its functions.
+
+\lp
+This document describes \MH/ from several perspectives.
+Particular emphasis is given to:
+the \MH/ user environment,
+advanced features of \MH/ which have proven to be particularly useful for
+sophisticated users of electronic mail,
+the user interface issues in \MH/,
+and the \mh5 distribution.
+The paper concludes with a summary of the authors' experiences with \MH/,
+and a discussion of future areas of enhancement.

+\section{Introduction}                         % mtr
+The UCI version of the Rand Message Handling System, \MH/,
+is a software system that performs two functions:
+\underbar{first},
+it interfaces a user to a message transport system,
+so the user may receive and send mail;
+\underbar{second},
+it permits the user to maintain an organized mail environment to facilitate
+the composition of new messages and the reading of old messages.
+In short,
+while not responsible for the delivery of messages,
+\MH/ aids the user in handling mail.
+
+\MH/ was originally developed by the Rand Corporation,
+and initially was proprietary software.
+The Department of Information and Computer Science at
+University of California, Irvine,
+shortly after joining the Computer Science Network (CSnet),
+acquired a copy of \MH/,
+and began additional development of the software.
+Since that time,
+the Rand Corporation has declared \MH/ to be in the public domain,
+and the UCI version of \MH/ has passed through four major releases.
+The current version, \mh5,
+is available from U.C.~Irvine for a nominal distribution fee,
+or may be retrieved from the University of Delaware via anonymous FTP.
+
+Much credit must be given to the initial designers and implementors of \MH/:
+Bruce Borden, Stockton Gaines, and Norman Shapiro.
+Although \MH/ has suffered significant development at UCI
+since Rand's initial release,
+the fundamental concepts of \MH/'s environs have remained nearly unchanged.
+In addition,
+the authors of the current release gratefully acknowledge the comments of the
+many sites which have run various releases of \MH/ in the past.
+In particular,
+the dozen or so beta test sites for \mh5
+provided tremendous help in stabilizing the current release.
+
+\MH/ runs on different versions of the \unix/ operating system
+(such as Berkeley~4.2\bsd/ and various flavors of v7).
+In addition,
+\MH/ supports four different message transport interfaces:
+\SendMail/\cite{EAllm83},
+the standard mailer for 4.2\bsd/ systems;
+\MMDF/\cite{DCroc79} and \MMDFII/\cite{DKing84},
+the Multi-Channel Memo Distribution Facility developed by the University of
+Delaware
+which forms the software-backbone for CSnet\cite{DCome83} mail relay service;
+SMTP,
+the ARPA Internet Simple Mail Transfer Protocol\cite{SMTP};
+and,
+a stand-alone delivery system.
+
+This paper is organized in a straight-forward fashion:
+Initially,
+the \MH/ philosophy of mail handling is presented,
+along with a description of the environment which the \MH/ user is given to
+process mail.
+Following this,
+certain advanced features of \MH/ are discussed in more detail,
+such as facilities for selecting messages,
+and ``advanced'' concepts in {\it draft} handling.
+In addition,
+user interface issues in mail handling are addressed,
+and the merits of \MH/'s approach is critically examined.
+Next,
+the \mh5 distribution package is described.
+Finally,
+we conclude by discussing the authors' experience with \MH/ development
+and introducing areas where \MH/ may be further developed.
+
+Although familiarity with \MH/ is not assumed on the part of the reader,
+some knowledge of the \unix/ operating system is useful.
+Appendix~A gives a short synopsis of the \MH/ commands.
+
+\section{The \MH/ Philosophy}                  % mtr
+Although \MH/ has many traits which tend to distinguish it from other systems
+which handle mail,
+there is a single fundamental design decision which influences the interface
+between \MH/ and the user:
+\MH/ differs from most other systems in that it is composed of many small
+programs instead of one very large one.
+This architecture gives \MH/ much of its strength,
+since intermediate and advanced users are able to take advantage of this
+flexibility.
+
+The key to this flexibility is that the \unix/ shell
+(usually the {\it C} shell or the {\it Bourne} shell),
+is the user's interface to \MH/.
+This means that when handling mail,
+the entire power of the shell is at the user's disposal,
+in addition to the
+facilities which \MH/ provides.
+Hence,
+the user may intersperse mail handling commands with other commands in an
+arbitrary fashion,
+making use of command handling capabilities which
+the user's shell provides.
+
+Furthermore,
+rather than storing messages in a complicated data structure
+within a monolithic file,
+each message in \MH/ is a \unix/ file,
+and each folder (an object which holds groups of messages)
+in \MH/  is a \unix/ directory.
+That is,
+the directory- and file-structure of \unix/ is used directly.
+As a result,
+any \unix/ file-handling command can be applied to any message.
+
+To the novice,
+this may not make much sense or may not seem important.
+However,
+as users of \MH/ become more experienced,
+they find this capability attractive.
+In addition,
+this approach is often quite pleasing to system implementors,
+because it minimizes the amount of coding to be performed,
+and given a modular design,
+changes to the software system can be maintained easily.
+There are, however, performance penalties to be paid with this scheme.
+This issue is considered later in the paper.
+
+Having described how \MH/ fits into the \unix/ environment,
+we now discuss the mail handling environment which is available to the \MH/
+user.
+
+\subsection{The \MH/ Environs}                 % jlr
+In the \file{\$HOME} directory of each \MH/ user, a file named
+\profile/ contains static information about the user's \MH/ environment, 
+and default arguments for \MH/ programs.
+For the latter case,
+each line of profile takes the form:
+\example program-name:\ options\endexample
+Each \MH/ program consults the user's \profile/ for its options.
+These options are consulted prior to evaluating any command-line arguments,
+and so provide the \MH/ user the capability to customize the defaults for each
+command.
+Futher, by using the \unix/ link facility,
+different names can be given to the same command.
+Since each \MH/ command looks
+in the \profile/
+for a component with the name by which it was invoked,
+it's possible to have different defaults for the same program.
+For example,
+it is not uncommon to link \pgm{prompter}
+(a simple prompting editor front-end)
+under the name \pgm{rapid} in the
+user's \file{bin/} directory, and add to the \profile/:
+\example rapid:\ -prepend\ -rapid\endexample
+As a result,
+when \pgm{prompter} is invoked as \pgm{rapid},
+it automatically uses the \switch{prepend} and \switch{rapid} options.
+
+The profile component \eg{Path:} is the path to the user's
+\MH/-directory, usually \Mail/.
+In addition to containing the user's folders,
+the \MH/-directory also contains {\it skeletons} and
+{\it templates} used by the \MH/ programs,
+and the user's \context/ file.
+This latter file has the same format as the user's \profile/,
+and contains the dynamic,
+context-dependent information about the user's environment.
+Whenever \MH/ looks for an \MH/-specific file,
+such as a template or skeleton,
+it first consults the user's \MH/-directory,
+and then a system-wide library area.
+
+The \MH/ user always has a {\it current folder},
+which is the folder in which
+the user is currently (or was last) working.
+Since any \MH/ program which deals with folders implicitly manipulates this
+information,
+the name of the  current folder is stored in the \file{context}
+component \eg{Current-Folder:}.
+Every folder has a {\it current message} known as \arg{cur}.
+These values are the defaults for \MH/ commands which
+accept folder and/or messages arguments.
+
+\MH/ programs make use of a set of envariables
+which further customize their behavior.
+The \file{\$MH} envariable, if present,
+specifies the name of an alternate profile for the user.
+This allows a user of \MH/ to
+easily maintain multiple mail-handling environments.
+
+In terms of command syntax,
+most \MH/ commands accept an optional {\it folder} argument,
+such as \arg{+outbox}.
+Unlike most \unix/ commands,
+all \MH/ commands have switches which are words, rather than single letters.
+Switches may be abbreviated to the least unambiguous prefix.
+All \MH/ commands also support a \switch{help} switch,
+which lists the syntax of the command along with available switches,
+and the version number of the command.
+Most \MH/ commands also take a \arg{msg} or \arg{msgs} argument
+which takes the form of a message number (\eg{1}), a message range (\eg{1-2}),
+a standard sequence name (\eg{cur}),
+or a user-defined sequence name (\eg{select}).
+
+\tagdiagram{1}{An \MH/ Session}{session}
+\subsection{An \MH/ Transcript}                        % jlr
+Figure~\session\ contains a transcript of a simple \MH/ session.
+First, \pgm{inc} is run to incorporate the new mail into the 
+user's \eg{+inbox} folder.
+
+A \pgm{scan} listing of the mail is printed while
+it is being incorporated.
+(The user could run \pgm{scan} explicitly to generate additional \pgm{scan}
+listings later on.)
+The \pgm{scan} listing gives the message number, followed
+by the date, message sender, and subject.
+(If the message originated from the user generating the listing,
+the \eg{to:} addressee is displayed instead of the sender.)
+If the subject is short,
+the first part of the message body is displayed after the characters \eg{<<}.
+The plus sign (`+') after
+the message number indicates the current message.
+
+The user \pgm{show\/}s the message, and decides to \pgm{repl\/}y.
+A reply draft
+is created using the headers of the message being replied-to,
+using the default \file{replcomps} template.
+The default editor, \pgm{prompter}, is called to edit the draft.
+When an EOT is typed, \pgm{prompter} exits and the
+user is left at the \whatnow/ prompt.
+The option \pgm{send} is chosen.
+Since there were no problems in posting the draft with the message transport
+system, 
+no additional output is produced.
+(\MH/ is not verbose by default.)
+
+The user then decides to compose a new message.
+The default skeleton, \file{components}, is copied to the draft,
+and \pgm{prompter} is once again called.
+After entering the addresses, subject, and body,
+the user then \pgm{send\/}s the \file{draft} from the \whatnow/ prompt,
+using \eg{send\ -verbose}, which causes
+\MH/ to list out the message addresses as it submits them
+to the message transport system.
+
+\section{Some \MH/ Features}                   % mtr
+We now consider certain advanced features in \MH/.
+These features have been chosen to demonstrate some useful capabilities
+available to the \MH/ user.
+
+\subsection{Message Sequences and Selection}   % jlr
+\MH/ has several built-in message sequence names, which may
+be used anywhere a \arg{msg} or \arg{msgs} argument is expected.
+These are:
+\arg{cur}, \arg{next}, \arg{prev}, \arg{first}, \arg{last}, and \arg{all}.
+Message ranges may also be specified.
+For example, \arg{all} is actually \arg{first-last}, and
+\arg{+mh\ last:5} references the last five messages in your
+\arg{+mh} folder.
+A powerful capability of \MH/ is the ability to use not only the pre-defined
+message sequence names,
+but also arbitrary user-defined message sequence names.
+
+Although all \MH/ programs recognize user-defined sequences when appropriate, 
+the \pgm{pick} and \pgm{mark} commands can create and modify 
+user-defined message sequences.
+The \pgm{mark} command allows low-level manipulation of sequences,
+and is not particularly interesting in our discussion.
+
+The \pgm{pick} command selects certain messages out of a folder.
+The criteria used for selection may be a search string and/or a date range.
+
+Searching is performed on either a specific header in the message
+(e.g., \eg{To:}),
+or anywhere within the message.
+By default,
+\pgm{pick} lists out the message numbers that matched
+the selection criteria.
+Thus, \pgm{pick} is useful in backquoted operations to the shell.
+For example, to scan all the messages in the current folder from ``frated'',
+the \MH/ user issues the command:
+\example scan\ \bq{pick\ -from\ frated}\endexample
+To perform more complicated message selection,
+user-defined sequences are employed.
+Supplying a \switch{sequence\ name}
+argument to \pgm{pick}, will cause it to define the
+sequence \arg{name} as those messages matched.
+
+Giving \pgm{pick} a list of messages causes it to limit its search to just
+those messages.
+For example,
+to find all the messages in the current folder from ``frated'' also dated
+before friday:
+\example pick\ -from\ frated\ -sequence\ select\\
+        pick\ select\ -before\ friday\ -sequence\ select\endexample
+With the first \pgm{pick} command,
+the sequence \eg{select} is defined
+to be all those messages from ``frated''.
+In the second command, only those messages already in the \eg{select}
+sequence are searched, and the \eg{select} sequence is redefined to be
+only those messages which are also
+dated before friday.
+Those messages could then be \pgm{show\/}n with:
+\example show\ select\endexample
+When a \switch{sequence\ name} argument is given to \pgm{pick},
+the default behavior --- listing the message numbers
+matched --- is inhibited.
+To re-enable this behavior, the \switch{list} option may be given.
+As a result,
+advanced users of \MH/ often put the following line in their \profile/:
+\example pick:\ -sequence\ select\ -list\endexample
+which allows them to easily make use of the \arg{select} sequence as the
+messages last selected with \pgm{pick}.
+
+Often it is desirable to act upon those messages which
+are {\it not} members of a given sequence.
+For this purpose,
+the \eg{Sequence-Negation:} profile entry is useful.
+If the name of a user-defined sequence is prefixed with the value of the
+sequence-negation profile entry,
+\MH/ commands will operate upon those messages which are {\it not} members
+of that sequence.
+For example, given a profile entry of:
+\example Sequence-Negation:\ not\endexample
+those messages which
+are not in the \arg{select} sequence could be \pgm{scan\/}'d with:
+\example scan\ notselect\endexample
+
+Obviously, some confusion could result if an attempt was made
+to define a sequence name
+which began with the sequence-negation string (e.g., \eg{notselect}).
+For this reason, \MH/ users will often use a single
+character,
+which their shell doesn't interpret,
+as their sequence-negation string
+(e.g., up-caret (`\^{}') for {\it C} Shell users,
+and exclamation-mark (`!') for {\it Bourne} shell users).
+
+\MH/ also provides a way of automatically remembering the last
+message list given to
+an \MH/ command.
+This facility is implemented by using a profile entry called
+\eg{Previous-Sequence:}.
+
+\subsection{Draft Handling}                    % jlr
+After the initial edit of a message draft,
+the \pgm{comp}, \pgm{dist}, \pgm{forw}, and \pgm{repl} programs
+give the user a \whatnow/ prompt.
+The valid responses include:
+\pgm{edit} to re-edit the draft,
+\pgm{quit} to exit without sending the draft,
+\pgm{send} to send the draft, and
+\pgm{push} to send the draft in the background.
+
+When the \pgm{send} option is given,
+the draft is posted with the message transport system.
+If there problems posting the draft,
+the \whatnow/ prompt is re-issued,
+so errors in the draft may be corrected.
+
+Since posting the draft can be slow,
+the \pgm{push} option allows the \MH/ user to send the draft in the
+background, and return immediately to the shell.
+If there are problems posting the message,
+the user will not see the diagnostics produced by
+the message transport system.
+For this reason,
+if \pgm{push} is used instead of \pgm{send},
+and the message is not successfully posted,
+\MH/ mails a message to the user
+containing any diagnostics which the message transport system produced
+along with a copy of the message.
+Later,
+the draft may be re-edited by entering \eg{comp\ -use}.
+
+A relatively new feature of \MH/ is the ability to use a folder to store
+multiple drafts.
+These drafts are kept in an ordinary \MH/ folder,
+and may be operated upon by \MH/ commands.
+To enable this feature,
+the \MH/ user selects a folder-name for the draft-folder,
+and creates an entry in the \profile/:
+\example Draft-Folder:\ +foldername\endexample
+From this point on,
+when a message is composed,
+the draft will be created as a message in that folder,
+instead of using the \file{draft} file in the user's \MH/ directory.
+Unfortunately,
+if posting problems occur on a message which has been \pgm{push\/}'d,
+it may be difficult to re-edit the draft with
+\eg{comp\ -use}.
+This might be the case if the user had started composing another message,
+while that first draft was being posted.
+In that event,
+the current-message in the draft-folder would no longer point
+to the failed draft.
+
+There is a solution for this problem, however.
+By default,
+\pgm{push} assumes the \switch{forward} option,
+which says that if the message draft fails to be posted,
+it should be forwarded back to the user in the
+error report which \pgm{push} generates.
+The failed draft may then be extracted with the \pgm{burst} program
+(discussed later).
+
+\subsection{BBoards}                           % mtr
+\MH/ has a convenient interface to the UCI BBoards facility\cite{MRose84a}.%
+\nfootnote{The UCI BBoards facility can run under either the \MMDF/ or
+\SendMail/,
+or in a more restricted form under stand-alone \MH/.}
+This facility permits the efficient distribution of interest group messages
+on a single host,
+to a group of hosts under a single administration,
+and to the ARPA Internet community.
+
+Although most readers are probably familiar with the concept of an interest
+group in the Internet context, a brief description is now given.
+Observant readers will notice that the distributed nature of the
+``network news'' (a.k.a.~USENET)
+tends to avoid many of the problems described below.
+
+Described simply, an interest group is composed of a number of subscribers
+with a common interest.
+These subscribers post mail to a single address, known as the
+{\it distribution} address (e.g., {\tx address@hidden
+From this distribution address, a copy of the message is sent to each
+subscriber.
+Each group has a {\it moderator},
+who is the person that runs the group.
+This moderator can usually be reached at a special address,
+known as the {\it request} address (e.g., {\tx address@hidden).
+Usually, the responsibilities of the moderator are quite simple,
+since the mail system handles distribution to subscribers automatically.
+In some interest groups,
+instead of each separate message being distributed directly to subscribers,
+a batch of (hopefully related) messages
+are put into a {\it digest} format by the
+moderator and then sent to the subscribers.
+(This is similar to a newsletter format.)
+Although this requires more work on the part of the moderator
+and introduces delays,
+such groups tend to be better organized.
+
+Unfortunately, some problems arise with the scheme outlined above.
+First, if two users on the same host subscribe to the same interest group,
+two copies of the message are delivered.
+This is wasteful of both processor and disk resources at that host.
+
+Second,
+some groups carry a lot of traffic.
+Although subscription to a group does indicate interest on the part of a
+subscriber,
+it is usually not interesting to get 50 or so messages delivered
+each day
+to the user's private maildrop,
+interspersed with {\it personal} mail,
+which is likely to be of a much more important and timely nature.
+
+Third, if a subscriber's address in a distribution list 
+becomes ``bad'' somehow and causes failed mail to be returned,
+the originator of the message is normally notified.
+It is not uncommon for a large list to have several bogus addresses.
+This results in the originator being flooded with ``error messages'' from
+mailers across the Internet stating that a given address on the list was
+bad.
+Needless to say,
+the originator usually does not care if the bogus addresses got a copy
+of the message or not.
+The originator is merely interested in posting a message
+to the group at large.
+On the other hand,
+the moderator of the group does care if there are bogus addresses on the list,
+but ironically does not receive notification.
+
+To solve these problems,
+the UCI BBoards facility introduces a new entity into the picture:
+a {\it distribution channel}.
+All interest group mail is handled by 
+the special mail system component.
+The distribution address for an interest-group
+maps mail for that interest-group to the distribution channel,
+which then performs
+several actions.
+First, if local delivery is to be performed,
+a copy of the message is placed in a global maildrop for the interest
+group with a timestamp and a unique number.
+Local users can read messages posted for the interest group by reading this
+``public'' maildrop.
+Second, if further distribution is to take place,
+a copy of the message is sent to the distribution address in such a way that
+if any of the addresses are bogus,
+failure notices will be returned to the local maintainer of the group
+address list, rather than the originator of the message.
+
+This scheme has several advantages:
+First, messages delivered to the local host are processed and saved once
+in a globally accessible area.
+The UCI BBoards facility supports software which allows a user to query an
+interest group for new messages and to read and process
+those messages in the \MH/-style.
+Second, once a host administrator subscribes to an interest group,
+each user may join or quit the list's readership without
+contacting anyone.
+Third, a hierarchical distribution scheme can be constructed to
+reduce the amount of delivery effort.
+Finally, errors are prevented from propagating.
+When an address on the distribution list goes bad,
+the list moderator who is responsible for the address is notified.
+If a local moderator does not exist,
+then the local PostMaster is notified (not the global group moderator).
+
+In addition to solving the problems outlined above,
+the UCI BBoards facility supports several other capabilities.
+BBoards may be automatically archived in order to conserve disk space and
+reduce processing time when reading current items.
+Also,
+the archives can be separately maintained on tape for access by interested
+researchers.
+
+Special alias files may be generated which allow the \MH/ user to shorten
+address entry.
+For example, instead of sending to {\tx address@hidden,
+a user of \MH/ usually sends to \eg{SF-Lovers} and the \MH/ aliasing
+facility automatically makes the appropriate expansion in the headers of the
+outgoing message.
+Hence,
+the user need only know the name of an interest group and not its global
+network address.
+
+Finally, the UCI BBoards facility supports {\it private} interest groups
+using the \unix/ group access mechanism.
+This allows a group of people on the same or different machines to conduct a
+private discussion.
+
+The practical upshot of all this is that the UCI BBoards facility automates
+the vast majority of BBoards handling from the point of view of both the
+PostMaster and the user.
+
+\MH/ provides three programs to deal with interest groups.
+The \pgm{bbc} program is used to check on the status of one or more groups,
+and to optionally start an \MH/ shell on those groups which the user is
+interested in.
+The \pgm{bbl} program can be used to manually perform maintenance on a
+discussion group beyond the normal automatic capabilities of the UCI BBoards
+facility.
+Finally,
+the \pgm{msh} program implements an \MH/ shell for reading BBoards,
+in which nearly all of the \MH/ commands are implemented in a single program.
+
+Observant readers may note that the use of \pgm{msh} is contrary to the \MH/
+philosophy of using relatively small, single-purpose programs.
+Sadly,
+the authors admit that this is true.
+In an effort to minimize use of system resources however,
+BBoards are kept in maildrop format instead of folders.%
+\nfootnote{When the message transport system delivers a message to a user
+it stores it in a single file, called a {\it maildrop}.
+Since many messages may be present in a single maildrop,
+(in theory) there is a unique string acting as a separator between messages
+in the maildrop.
+Although this is convenient for storage of messages,
+it makes retrieval more difficult unless a separate index into the maildrop
+is kept.
+This latter approach is taken by the \pgm{msg} program available with \MMDFII/
+and by \pgm{msh} as well.}
+Some research has gone into overcoming this problem to restore
+\MH/'s purity of purpose,
+but all solutions proposed to date are either unworkable or require
+significant recoding of \MH/'s internals.
+
+\subsection{Bursting}                  % jlr
+Internet interest group mail is often sent out in digest form.
+The experienced \MH/ user may wish to deal with the digest messages on
+an individual basis, however.
+The \pgm{burst} program allows the \MH/ user to extract these digest
+messages,
+and store each as an individual \MH/ message.
+
+\pgm{Burst} will also extract forwarded messages generated by \pgm{forw}
+(or the forwarded message in the error report generated by \pgm{push},
+as described above).
+Although \pgm{burst} cannot always decapsulate
+messages encapsulated by sites not running \MH/,
+it adheres to the proposed standard described in \cite{MRose85b}.
+
+\subsection{Distributed Mail}                  % mtr
+The ARPA Internet community consists of many types of heterogeneous nodes.
+Some hosts are large mainframe computers,
+others are personal workstations.
+All communicate using the \milstd/ TCP/IP protocol suite\cite{IP,TCP}.
+Messages which conform to the Standard for the Format of ARPA Internet Text
+Messages\cite{DCroc82}
+are exchanged using the Simple Mail Transfer Protocol\cite{SMTP}.
+
+On smaller nodes in the ARPA Internet,
+it is often impractical to maintain
+a message transport system (e.g., \SendMail/).
+For example,
+a workstation may not have sufficient resources (cycles, disk space)
+in order to permit an SMTP server and associated local mail delivery system
+to be kept resident and continuously running.
+Furthermore,
+the workstation could be off-net for extended periods of time.
+Similarly,
+it may be expensive (or impossible) to keep a personal computer
+interconnected to an IP-style network for long periods of time.
+In other words,
+the node is lacking the resource known as ``connectivity''.
+
+Despite this,
+it is often desirable to be able to manage mail with \MH/ on these smaller
+nodes,
+and they often support a user agent to aid the tasks of mail handling.
+To solve this problem,
+a network node which can support a message transport entity
+(known as {\it service} host) offers
+a maildrop service to these less endowed nodes
+(known as {\it client} hosts).
+The Post Office Protocol\cite{JReyn84} (POP) is intended to permit a
+workstation to dynamically access a maildrop on a service host to pick-up
+mail.%
+\nfootnote{Actually,
+there are three different descriptions of the POP.
+The first, cited in \cite{JReyn84},
+was the original description of the protocol,
+which suffered from certain problems.
+Since then,
+two alternate descriptions have been developed.
+The official revision of the POP\cite{MButl85},
+and the revision of the POP which \MH/ uses
+(which is documented in an internal memorandum in the \MH/ release).
+This paper considers the POP in the context of the \MH/ release.}
+The level of access includes the ability to
+determine the number of messages in the maildrop and the size of each message,
+as well as to retrieve and delete individual messages.
+More sophisticated implementations of the POP server
+are able to distinguish between the header and body portion of each message,
+and send $n$ lines of a message to the POP client.
+This capability is useful in thinly connected environments where conservation
+of bandwidth is important.
+By utilizing a more intelligent POP client,
+a user may generate ``scan~listings'' and decide dynamically which messages
+are worth taking delivery on.
+The philosophy of the POP is to put intelligence in the 
+POP clients and not the POP servers.
+
+The current release of \MH/ supports the above model fully.
+A POP client program is available to retrieve a maildrop from a POP service
+host.
+In addition,
+using the SMTP configuration for delivery in \MH/
+(either in conjunction with \SendMail/ or the \MMDF/),
+a user is able to specify a search-list of service hosts (and/or networks)
+to try to post mail.
+Using this search-list,
+when an \MH/ user posts a draft,
+the \pgm{post} program will attempt to establish an SMTP connection
+with each host in the search-list to post the message until it succeeds.
+Initial experimentation using the POP and \MH/
+in a local network environment has proved quite successful.
+
+\section{User Interface Issues in \MH/}                % mtr
+At this point,
+it is perhaps useful to take a step backwards and examine the success
+and problems of \MH/'s approach to user interfaces.
+
+\subsection{Creeping Featurism}                        % mtr
+A complaint often heard about systems which undergo substantial development
+by many people over a number of years, is that more and more options are
+introduced which add little to the functionality but greatly increase the
+amount of information a user needs to know in order to get useful work done.
+This is usually referred to as {\it creeping featurism}.
+
+Unfortunately \MH/,
+having undergone six years of off-and-on development by ten or so
+well-meaning programmers (the present authors included),
+suffers mightily from this.
+For example,
+the \pgm{send} command has twenty-five visible switches,
+and at least nine hidden switches,
+for a total of thirty-four.
+The poor user who types \example send\ -help\endexample watches the options
+scroll off the screen
+(since the \switch{help} switch also lists out four other lines of
+information).%
+\nfootnote{Recently,
+this was fixed by compressing the way in which switches are presented.
+The solution is only temporary however,
+as \pgm{send} will no doubt acquire an {\it endless} number of switches in
+the years to come.}
+The sad part is that all of these switches are useful in one form or another.
+
+There are a lot of good things to be said for the
+``one program, one function'' philosophy of system design.
+In the \MH/ case, however,
+each program really does only one mail handling activity
+(with a few minor exceptions).
+The options associated with each command are present to modify the program's
+behavior to perform similar, but slightly different tasks.
+In further defense of \MH/,
+note that there are~32 \MH/ commands at present,
+all performing different tasks.
+
+The problem with creeping featurism though,
+is that while the functionality of the system increases sub-linearly,
+the complexity of the system increases linearly.
+That is,
+although the number of switches that a program takes might double,
+it is unlikely that the program's functionality or capabilities will double.
+
+\subsection{Templates versus Switches}         % mtr
+One way to trim the explosion of available options,
+while still increasing functionality,
+is to introduce options with a richer domain.
+Hence,
+instead of using options which take {\it on} or {\it off} forms
+or simple numeric or string values,
+the possible values which an option might take on is given a large space.
+There are several ways that this might be accomplished.
+
+\tagdiagram{2}{Draft Skeleton}{components}
+The \pgm{comp}, \pgm{dist}, and \pgm{forw} programs
+use draft {\it skeletons} (simple form fill-in files) to construct the
+general format of the draft being composed.
+An example of a draft skeleton used for composing new messages
+(by \pgm{comp\/}) is shown in Figure~\components.
+The approach is to let the user specify (and later edit) both arbitrary
+headers of draft and the body of the draft.
+Note while most of the fields are empty,
+the first \eg{Fcc:} field already contains a value.
+By using the simple prompting editor, \pgm{prompter},
+the user can speedily enter the headers of the message.
+The \pgm{prompter} program given the skeleton in Figure~\components\ would
+prompt the user for the contents of each field,
+except for the second \eg{fcc:},
+which it would include verbatim.
+It would then read the body of the message up to an end-of-file.
+Naturally,
+the \MH/ user is free to use {\it any} editor to edit {\it any} part of the
+draft (headers or body).
+This example 
+demonstrates the flexibility achieved by not limiting what headers a
+draft may contain (which most mail sending programs do),
+while still retaining the simplicity of being able to treat the entire
+message draft as a \unix/ file.
+
+\tagdiagram{3}{Reply Template}{replcomps}
+Another more interesting approach is used by the \pgm{repl} command,
+which constructs a draft in reply-to a previously received message.
+Instead of adding switches to indicate which fields of the draft should be
+derived from the message being replied-to,
+and how they should be derived,
+a single option,
+the ability to specify a {\it template}, was made available.
+An example of a reply template is shown in Figure~\replcomps.
+Put simply,
+based on the presence of certain fields in the message being replied-to,
+and a few switches given by the user,
+using the reply template,
+\pgm{repl} generates the reply draft automatically.
+
+\tagdiagram{4}{The \file{tripcomps} Reply Template}{tripcomps}
+This facility, for example,
+can be used to generate automatic replies.%
+\nfootnote{\MH/ supports the notion of a user-defined {\it mail hook}
+which is invoked each time a user receives mail.}
+One function might be to write a \pgm{rcvtrip} shell script
+which automatically answered messages when mail wasn't being read for a
+period of time
+(e.g., while attending a conference).
+An example of a reply template at the heart of such a script
+is shown in Figure~\tripcomps.
+
+\tagdiagram{5}{The \file{bombcomps} Reply Template}{bombcomps}
+Finally,
+another application might be to utilize
+the highly useful letter bomb protocol.%
+\nfootnote{The authors wish to credit Ron Natalie of the Ballistics Research
+Laboratory in Aberdeen, Maryland for formalizing the
+use of this protocol in the ARPA Internet community.}
+The important thing to note about this template is that it generates not only
+the headers of the reply draft (with a creative \eg{Reply-to:} address),
+but the body as well.
+Hence,
+the commands
+\example
+    repl\ -form\ bombcomps\ -noedit\ ;\ rmm\\
+    What\ now?\ push%
+\endexample
+are very handy for dealing with disturbing mail in a straight-forward manner.
+Of course, \pgm{repl} could be linked to \pgm{bomb} in the user's \file{bin/}
+directory and an appropriate line could be added to the user's \MH/ profile,
+in order to further shorten type-in.
+
+\tagdiagram{6}{Display Template}{mhlforward}
+A variation on the reply template is the {\it display template}.
+A display template, as used by the \pgm{mhl} program,
+contains instructions on how to format a message.
+In addition to being used by \pgm{show}, et.~al.,
+the \pgm{forw} program can also use a display template to format each
+message being forwarded.
+Similarly,
+although \pgm{repl} uses a reply template to construct the draft
+being composed,
+it also may use a display template to format the body of the message
+being replied-to for enclosure in the reply.
+Furthermore,
+the \pgm{post} program may use a display template to format the body of a
+blind-carbon-copy.
+An example of a display template used for formatting forwarded messages
+is shown in Figure~\mhlforward.
+
+As with reply templates,
+display templates can offer a lot of functionality.
+For example,
+the one line display template:
+\example
+    body:nocomponent,overflowtext=,overflowoffset=0,width=10000%
+\endexample
+can be used to extract the body of a message,
+while ignoring the headers.
+Hence,
+if a \pgm{shar} archive arrived in the mail,
+a convenient way to unpack it,
+assuming the above display template was called \file{mhl.body},
+would be:
+\example show\ -form\ mhl.body\ |\ sh\endexample
+
+The biggest win with display templates,
+of course,
+is that all those annoying header lines which mailers
+everywhere generate can be simply and easily filtered out.
+
+\subsection{Modularity versus Monolithicity}   % jlr
+Since \MH/ is a set of programs
+which perform separate tasks,
+as opposed to being a single, monolithic program,
+the power of the shell is used directly to aid in mail-handling.
+One powerful capability which this design achieves is the ability to extend
+the \MH/ command set,
+by developing shell scripts which use the standard \MH/
+programs to accomplish complicated or specialized tasks.
+
+\tagdiagram{7}{The \pgm{mpick} Script}{mpick}
+For example,
+in the \MH/ distribution there is a shell script
+called \pgm{mpick} (shown in Figure~\mpick)
+which tries to locate all the messages which pertain to a given discussion,
+by looking at the \eg{Message-ID:} and \eg{In-reply-to:} headers,
+to find matching message-ids.%
+\nfootnote{Note that the shell scripts included in the \MH/ distribution
+are written for the {\it Bourne} shell,
+and have a `:' as the first character of the first line,
+so they will be portable to all versions of \unix/,
+not just those which support the
+Berkeley `\#!' enhancement.}
+
+\tagdiagram{8}{The \pgm{append} Editor}{appended}
+Unfortunately, some parts of \MH/ are somewhat monolithic.
+An example of this is the \whatnow/ prompt.
+There are only a few options at this prompt,
+and one cannot give a normal shell command.
+Some \MH/ users seem to feel that more options should be added to
+the \whatnow/ prompt, such as an \pgm{insert-file} option.
+It was argued that just about any editor would allow you to 
+insert a file, and another \whatnow/ option was not needed.
+These users persisted, however, so the
+problem was solved, by writing a trivial shell
+script ``editor'' (see Figure~\appended)
+which could be invoked by the \pgm{edit} option:
+\example What now?\ edit\ append\ filename\endexample
+
+A better interface at this point is really needed, however.
+One possibility is to simply pass any unrecognized commands on
+to a shell for interpretation, supplying the path name of the draft file
+as an argument.
+A solution which shows more promise is to give you a sub-shell
+{\it instead} of the \whatnow/ prompt,
+and setup certain envariables so that
+the \MH/ commands would act upon the \file{draft} by default.
+For example, \pgm{show} with no \arg{msgs} arguments
+would show the draft instead of the current message.
+This alternative has recently been implemented and is under testing.
+
+\section{The \MH/ Distribution}                        % mtr
+The \mh5 distribution is now briefly described,
+both in terms of static configuration methods
+and dynamic tailoring.
+Appendix~B describes the mechanics of receiving an \mh5 distribution.
+
+\subsection{Configurable \MH/}                 % jlr
+The \MH/ distribution currently runs on a large number of different \unix/
+versions,
+ranging from MicroSoft XENIX to Berkeley 4.2\bsd/.
+All the code which is specific to a particular target environment is
+enabled via the C-preprocessor \eg{\#ifdef} mechanism,
+so compilation under different versions of \unix/ is trivial.
+There are,
+however,
+a large number of compile-time options which may vary from site to site,
+so an automated configuration method was needed.
+
+\tagdiagram{9}{Sample \MH/ Configuration File}{mhconfig}
+The \MH/-installer must create a configuration file,
+which contains a list of the compile-time options
+and the values which are desired for them.
+Compile-time options include the installation location for \MH/,
+what kind of message transport system is to be used,
+and the default editor for the installation.
+An example of such a configuration file is shown in Figure~\mhconfig.
+
+After creating this file (several examples are included in the distribution),
+the installer runs the \pgm{mhconfig} program,
+which customizes the \file{Makefile\/}s and some of the programs,
+for that site's particular installation.
+No hand-editing of any source code should be necessary,
+under normal circumstances.
+
+\subsection{Interface to the Message Transport System} % jlr & mtr
+\MH/ will run with a number of message transport systems,
+including \SendMail/, \MMDFII/, and a small stand-alone system.
+One flexible method of posting mail is through an SMTP connection.
+There are a couple of major wins in using this configuration: 
+First,
+none of the \MH/ programs need to know where the interface programs to
+the message transport system are located,
+which makes them easier to move between systems.
+Second,
+mail can be posted on relay hosts,
+and the local host of an \MH/ user may not need a message transport system at
+all (as alluded to in the preceeding discussion on the POP).
+
+\tagdiagram{10}{Sample MTS Tailor File}{mtstailor}
+Those parts of \MH/ which interact with the local message transport agent
+read additional tailoring information when they start.%
+\nfootnote{This simple facility is based on a more extensive
+tailoring capability found in \MMDFII/.}
+This information includes
+the location of standard and alternate maildrops,
+maildrop delimiter strings,
+the locking directory and locking style,
+and other tailoring information specific for the particular
+message transport system in use
+(e.g., the default server search-list when mail is posted with the SMTP).
+In most cases,
+by using a tailor file,
+each site running a similar \MH/ configuration is able to simply transfer
+\MH/ binaries between hosts.
+An example of such a tailor file is shown in Figure~\mtstailor.
+
+A continuing question which is often raised is how intelligent should user
+agents (like \MH/ and UCB \pgm{Mail}\/) be with respect to the environment in
+which they operate.
+At present, \MH/ likes to determine 
+the official hostnames for addresses when posting mail.
+Many argue that this is improper or unnecessary behavior for a user agent,
+and that the local message transport agent should handle these functions.
+Unfortunately,
+this implies that the message transport agent should munge headers when mail
+is posted to remove local host aliases and only permit address fields with
+fully-qualified addresses.
+Sadly, neither \SendMail/ nor \MMDFII/ really gets this right
+(flames to \file{/dev/null} please).
+The current \MH/ maintainers believe that the resolution of host aliases to
+official names should be a well-supported interface with the local message
+transport agent.
+However, to provide equal time to those who hold opposite views,
+\MH/ supports a configuration option called \eg{DUMB} which disables \MH/'s
+attempts to resolve addresses into fully-qualified strings.
+
+\section{Concluding Remarks}                   % jlr and mtr
+While \MH/ has undergone significant development since
+the original
+Rand release, the authors have
+tried to keep the fundamental concepts of
+\MH/ unchanged.
+                                               % specific vs. general
+The authors have continually had to battle against
+well-meaning \MH/ users who wanted to make \MH/
+more like other (less powerful) user agents.
+More and more ``features'' were often suggested for \MH/,
+usually at the expense of making \MH/ less general, and more specific.
+In nearly all cases, the ``features'' which these users wanted
+were already present in \MH/ in a slightly different form,
+or could be realized by simply writing a short shell script.
+A classic example is the repeated requests by one user to have \pgm{dist}
+take a list of messages rather than a single message and distribute each one
+of them in turn.
+A simple shell script which called \pgm{dist} repeatedly,
+perhaps with ``canned'' arguments so the user typed in addressing information
+only once, would easily meet this request.
+
+                                               % generality
+A number of \MH/ comands have a large number of options.
+When adding options, the authors have tried to make the options
+general, while still accomodating the requests of specific users.
+An example of a specific request which was implemented as a
+general feature is the \eg{Previous-Sequence} profile entry
+(mentioned above).
+If you use this profile entry, every \MH/ command is forced to write
+out \context/ changes, making every command somewhat slower.
+Since only a few users wanted this capability, it was implemented
+in such a way that users who didn't want it, didn't have to pay
+the cost of slowing down every \MH/ command.
+
+                                               % naive user :: MH
+\MH/ has a powerful tailoring capability provided by the \profile/.
+Using profile entries, users may
+customize their own environment without affecting others.
+Novice users often take advantage of the \MH/-tailoring
+capabilities to try to make \MH/ work similarly to
+other user agents they've used.
+This has the advantage of allowing them to quickly begin
+using \MH/ to handle their mail.
+However, since these novice users don't take advantange of all the
+capabilities of \MH/,
+they frequently will complain about things they think can't
+be done with \MH/, or could be done ``better'' some other way.
+Fortunately,
+as these users become more experienced with both \MH/ and \unix/,
+they can modify their environment to take better advantage of
+all of \MH/'s capabilities.
+Novice \MH/ users who see features lacking
+are encouraged to take a better look at what \MH/ {\it can} do,
+instead of trying to make \MH/ into something it isn't.
+This may sound rather inflammatory,
+but it would really be a much nicer world for us all if users of software
+systems would read the manual prior to asking questions.
+
+                                               % speed consideration
+For a moment, let's consider the evolution of one \MH/ feature which has
+proved itself to be very useful.
+As users began employing \MH/ to handle their mail,
+the number of messages that could be processed
+in a given amount of time increased greatly.
+As the volume of messages increased however,
+it became clear that some \MH/ operations were too slow,
+in particular the interaction with the (slow) message transport system.
+To overcome this problem, the \pgm{push} option
+was added at the \whatnow/ prompt.
+Originally, this option was hidden from novice users
+and did little more than send the message in the background:
+any output generated by
+the background \pgm{send} process would be printed
+asyncronously on the terminal.
+If a message failed posting with the message transport system,
+it would simply be left in the \file{draft} file.
+
+Gradually, other features were added to \pgm{push}.
+Since users wanted to be able to send more than one draft
+at a time, \pgm{push} was changed to optionally
+rename the draft file before posting it.
+(This is what the hidden \switch{unique} option does.)
+Having message transport system diagnostics
+written asyncronously on the user's terminal was annoying,
+so \pgm{push} was made to intercept these diagnostics,
+and mail the user a report containing them.
+Although the diagnostic report mailed back by \pgm{push} contains
+the name of the draft which failed,
+a useful added feature was the ability to have \pgm{push}
+include the failed draft as well.
+Eventually, the draft-folder mechanism was implemented to make
+handling multiple message drafts much easier.
+
+
+\subsection{TODO}                              % mtr
+There are, no doubt, a number of improvements which could be made to \MH/.
+At the present time,
+what further development should \MH/ suffer?
+Although not by any means inclusive,
+here's a list:
+\smallskip
+{\advance\leftskip by\parindent
+\item{1.} Performance Enhancements\hbreak
+Hardware gets faster all the time, but people always complain that software
+is too slow.
+Owing to its user interface style,
+\MH/ is somewhat slower than monolithic programs like UCB \pgm{Mail}.
+It would be nice if \MH/ could be tuned or accelerated somehow.
+
+\item{2.} Port to System~5\hbreak
+\MH/ runs on 4.2\bsd/~\unix/ and Version~7 variants.
+It should not be difficult to port \MH/ to a SYS5 environment.
+This should significantly increase the number of hosts
+on which \MH/ can run.
+The authors,
+lacking a SYS5 machine (and experience with SYS5) to perform the port,
+are actively seeking a System~5 guru to attempt this feat.
+
+\item{3.} Interface to the Network News\hbreak
+Not all sites that run \MH/ are in the ARPA Internet,
+and as such the UCI BBoards facility may not be of much use to them.
+A good \MH/ interface to the network news would allow users on hosts with a
+news feed to employ the same interface for reading and sending both mail and
+news.
+
+\item{4.} Programmed Instruction for Beginners\hbreak
+The complexity of \MH/ is often intimidating to new users.
+It would be nice to develop a set of \pgm{learn} lessons for those users who
+don't like \pgm{man} pages and non-interactive tutorials.
+
+\item{5.} Message List Expansion\hbreak
+At present, when a list of messages is given to an \MH/ command,
+it expands the list and processes each message in numerical order
+rather than the order in which the messages were given
+(e.g., \eg{show\ 2\ 1} \pgm{show\/}s message~1
+and then message~2).
+It would be nice if \MH/ processed messages in the order
+they were given.
+
+\item{6.} Context Changes\hbreak
+In nearly all cases,
+an \MH/ command does not write out context changes until it is about to exit
+successfully.
+There is some controversy as to whether this is the correct behavior
+in all cases.
+Some argue that once an \MH/ command has fully parsed its argument list,
+the context should be updated.

+\appendix{A}{An MH Session}
+
+\tagdiagram{A1-1}{Sending Encrypted Mail}{sendmail}
+In the following,
+the user \eg{Marshall\ T.\ Rose} logged onto host \eg{udel-dewey},
+wishes to send a message to a user known as
+the \eg{UCI\ Portal} (a system maintenance account).
+As shown in Figure~\sendmail, line~1,
+the user first establishes a mapping between the name \eg{UCI\ Portal} and
+the address {\tx address@hidden
+Once this mapping is performed,
+it remains in effect until the user indicates otherwise to the \TMA/.
+When the \pgm{tma} program is invoked,
+it consults the \TMA/ database to see if that user is known.
+If not,
+it contacts the \KDS/ to ask for the \KDS/ ID associated with the user.
+If the response is successful (in this case, the \KDS/ ID is \eg{3}),
+then the \TMA/ updates its database.
+The \pgm{tma} program indicates in its output the \KDS/ ID associated with
+the user,
+along with all known addresses (in this case, only one).
+So, once the name to address mapping has been described the user,
+the user agent, \MH/, deals only with the address,
+while the trusted mail agent deals with the name and \KDS/ ID aspects of the
+user.
+
+Next, the \pgm{comp} program is invoked to compose a new draft on line~5.
+The user addresses the local user \eg{uci} in the To: field,
+and indicates that a plaintext copy should be kept in the folder \eg{+outbox}.
+After entering the subject and text of the draft,
+the user enters \whatnow/ level on line~13.
+At this point,
+the user directs \MH/ to send the draft in encrypted form.
+The resulting output is verbose (a default for \pgm{send} for this user)
+but instructive.
+Initially,
+all addresses in the draft are verified on lines~14 to~17.
+Two forms of verification occur:
+first, the \MTS/ is asked to verify the address as much as possible.
+For local addresses,
+the \MTS/ decides if the name has a maildrop associated with it.
+For remote addresses,
+the \MTS/ decides if the host is known to it.
+The second type of verification occurs with the \TMA/.
+For all addresses,
+the \TMA/ is asked if it can find a mapping from the address to a \KDS/ ID.
+
+The reason \MH/ goes to all this trouble is a philosophical issue.
+Since the copy of the encrypted draft is different for each recipient,
+\pgm{post} tries to verify that all recipients can be successfully posted
+prior to actually posting the different ciphertext versions of the draft.
+This behavior is not optimal in terms of cycles,
+but is perhaps ``correct'' from a \UA/ perspective.
+
+Finally, the draft is actually posted, and the folder carbon-copy is filed.
+
+\tagdiagram{A1-2}{Receiving Encrypted Mail}{recvmail}
+Some time later, the UCI portal is informed that new mail has arrived.
+As shown in Figure~\recvmail,
+the \pgm{inc} program is run.
+The \eg{E} prior to the date of the message indicates that \pgm{inc} has
+detected the message to be encrypted.
+Since the user did not inhibit \pgm{inc} from deciphering the message,
+it proceeds to do so.
+
+\tagdiagram{A1-3}{Message Prior to Decryption}{before}
+\tagdiagram{A1-4}{Message After Decryption}{after}
+Finally, it may be instructive to see what the encrypted message looked like
+when it was delivered to the portal's maildrop,
+and the final message after deciphering.
+Figures~\before\ and~\after\ show these respectively.
+In particular,
+note that the \eg{X-KDS-ID:} field has been introduced in Figure~\after\
+after successfully deciphering the message.
+The presence of this field authenticates the sender of the message.

+\appendix{B}{A Short Exchange}
+
+The simple nature of the interchange between the user and \MH/
+in Appendix~A completely hides any interactions between the \TMA/
+and the \KDS/.
+Let us briefly examine an exchange that might occur
+after the destination \TMA/ receives the message shown in Figure~\before.
+
+To begin,
+the \TMA/ must ascertain what it knows about the sender of the message,
+which claims to have a \KDS/ ID of~17.
+That is,
+the \TMA/ must first consider what key relationships it has with the sender.
+For the sake of argument,
+suppose that this purported subscriber is unknown to the \TMA/.
+In this case,
+the first step it must undertake is to ascertain the validity of this
+subscriber.
+
+\tagdiagram{B1-1}{Ascertaining the Sender}{rui}
+As shown in Figure~\rui\ on lines~1--7,
+the \TMA/ does this by establishing a connection to the \KDS/ and issuing an
+{\it request identified user} (RUI) MCL.%
+\nfootnote{In point of fact,
+the {\it very} first thing that the \TMA/ does after connecting to the \KDS/
+is verify that the key relationships between the \KDS/ and the \TMA/ are
+valid (have not expired).
+If the key relationship between the two has expired,
+the \TMA/ issues a {\it request service initialization} RSI MCL to
+establish a new key relationship.
+This relationship contains a {\it key-encrypting key} (KK)
+and an {\it authentication key} (KA).
+Once a valid key relationship exists between the \KDS/ and the \TMA/,
+transactions concerning other key relationships may take place.}
+If the response by the \KDS/ is positive,
+the \TMA/ will use the information returned when generating the
+\eg{X-KDS-ID:} field for authentication.
+The response \CSM/ returned by the \KDS/ includes
+an {\it authentication checksum} (the MAC field on line~15)
+and a {\it transaction count} (the CTA field on line~12)
+to prevent spoofing by a process pretending to be the \KDS/.
+The \TMA/ then acknowledges that the response from the server was acceptable
+on lines~18--24.
+
+The next step is to ascertain the actual key relationship used to encrypt the
+structure $m$, which appears after the identifying string.
+The \TMA/ consults the IDK field in $m$,
+and if this relationship is unknown to it,
+then the \KDS/ is asked to disclose the key relationship.
+
+\tagdiagram{B1-2}{Ascertaining the Key Relationship}{rsi}
+As shown in Figure~\rsi\ on lines~1--9,
+This is done by issuing a {\it request service initialization} (RSI) MCL
+and specifying the particular key relationship of interest.
+The \KDS/ consults its database,
+and if the exact key relationship between the two indicated \TMA/s can be
+ascertained,
+it returns this information.
+The key relationship
+is encrypted using the key relationship between the \KDS/ and the \TMA/,
+and the usual count and authentication fields are included.
+
+Once the \TMA/ knows the key relationship used to encrypt the structure $m$,
+it can decider the structure and ascertain the KD/IV/KA triple used to
+encrypt the body of the message.

+\appendix{C}{Differences between the ANSI and TTI drafts}
+
+The differences between the \ansi/ draft standard for
+financial institution key management,
+and the \TTI/ draft's specification for trusted mail handling,
+are considered.
+
+The concept of a {\it key distribution center}
+(\CKD/ in the \ansi/ draft, \KDC/ in the \TTI/ draft)
+environment differs.
+In the \ansi/ draft,
+only one party talks to the {\it key distribution server} (\KDS/);
+in the \TTI/ draft,
+both parties talk to the \KDS/.
+This leads to a number of differences in the two protocols.
+The reason for this shift in the \TTI/ draft is somewhat subtle:
+although both parties can talk to the \KDS/,
+the {\it mail transfer system} (\MTS/)
+environment is such that both {\it user agents} (\UA/s) are unable to
+contact each other in real-time.
+Hence, a detailed two-way protocol between them is prohibitively expensive.%
+\nfootnote{In the words of Einar A.~Stefferud:
+``Every interesting connection has at least two end-points~---~connections
+with only one end-point are always uninteresting.''}
+
+Before discussing the differences between the two drafts,
+let us consider the differences in the two environments:
+in the electronic mail environment,
+the two end-to-end peers need not be simultaneously online.
+Electronic mail relies on a communication service with potentially large
+delays in transit between {\it message transfer agents} (\MTA/s).
+A basic concept of ``mail'' is that an originator must release the enveloped
+message to a ``transfer agent'' before delivery can be attempted to a
+recipient.
+In contrast,
+in the electronic funds environment,
+the two peers make use of a virtual-circuit service.
+This means that they can synchronize much easier
+and inter-operate in a more direct fashion.
+
+Service protocols are based on the notion of requests and responses.
+A client issues a request to a server,
+the server processes the request and returns a response.
+Depending on the complexity of the protocol,
+the client may now respond to the server's message,
+or might issue a new request,
+or might terminate the connection.
+
+As delays in the network increase,
+along with the possibility of loss or corruption or re-ordering of messages,
+it becomes more difficult to implement a service protocol.
+In the case of a high-level protocol making use of a virtual-circuit service,
+most problems can be ignored,
+as the virtual-circuit service masks out problems in the network
+by using sequences, positive (and/or negative) acknowledgments, windows,
+and so on.
+
+Sadly, electronic mail cannot utilize a virtual-circuit throughout the \MTS/
+(although individual \MTA/-wise connections are (in theory) virtual-circuit
+based).
+This means that implementing a real-time or interactive
+service protocol between two endpoints (a.k.a.~\UA/s)
+in the \MTS/ is very difficult.
+As a result,
+the complexity of an end-to-end protocol in the \MTS/
+(in terms of requests and responses)
+is severely constrained.
+For all practical purposes,
+an \MTA/ can assume datagram service and nothing else:
+messages might be re-ordered;
+messages might not reach their destination;
+messages might be corrupted (though this is unlikely);
+in cases of failure, a notice might be generated, or might not.
+
+In terms of the environment in which {\it cryptographic service messages}
+(\CSM/s) must flow,
+the high degree of delay and uncertainty make the implementation of a complex
+end-to-end protocol between \UA/s prohibitively expensive.
+Hence, a \KDC/ is needed,
+to which each \UA/ can connect using a virtual-circuit service,
+at posting and delivery time.
+The \TTI/ draft terms such a user agent a {\it trusted mail agent} (\TMA/).
+Since both \TMA/s can connect to the \KDS/ at different times using different
+media,
+the \KDS/ maintains state information about the key relationships between
+different \TMA/s and manages those relationships appropriately.
+Since connections to the \KDS/ can be expensive in terms of resources,
+each \TMA/ caches information received from the \KDS/ appropriately.
+
+That's the gist of the argument as to why the \TTI/ draft differs from the
+\ansi/ draft.
+It might be possible to include \CSM/s in the messages which \UA/s exchange,
+but management of these \CSM/s can not be done reliably or in a straightforward
+fashion owing to the datagram nature of the service offered by the \MTS/.
+Finally, it should be noted that in the \TTI/ draft,
+the \KDS/ never initiates a connection with a \TMA/,
+rather it is the \TMA/s which connect to the \KDS/.
+
+In the following,
+the differences between the two drafts are highlighted.
+Minor differences between the two are not discussed.
+
+In the \ansi/ draft,
+$\S 4.2$ (p.~22) discusses the requirements for the automated key
+management architecture.
+The \TTI/ draft has somewhat more ``depth'',
+since the \ansi/ draft does not make use of a {\it master key} (MK)
+to fully automate the distribution of {\it key-encrypting keys} (KK).
+
+The \ansi/ draft states that once a KK-relationship is discontinued by either
+of that pair,
+the relation is not to be re-used for any subsequent activity.
+This can't be guaranteed in the prototype implementation.
+If one of the \TMA/s wishes to discontinue a key,
+not only does it have to inform the \KDS/,
+but the other \TMA/ as well.
+Since the \TTI/ draft does not permit \CSM/s between \TMA/-peers,
+the latter action doesn't seem possible.
+However, there is a solution.
+Whenever a message is deciphered,
+the \TMA/ checks the effective date of the key used to
+encrypt a message it has received,
+and if the key is newer than the one it currently uses,
+it considers the older key to be discontinued.
+
+Furthermore,
+although the environment in the \TTI/ draft is that of a key distribution
+center,
+the notion of an {\it ultimate recipient} is not present,
+since all clients connect to the \KDS/ at one time or another.
+In addition,
+the differences between the environs envisioned by the two drafts
+become even more pronounced when one considers that the \KDS/ distributes
+key-encrypting keys to \TMA/s,
+although the \ansi/ draft specifically prohibits this.
+
+Finally,
+there is another important technical difference between the two
+drafts:
+every request to the \KDS/ by the \TMA/
+results in a specifically defined response from the \KDS/ to the \TMA/.
+Furthermore,
+if the \KDS/ responds in a positive manner,
+then the \TMA/ acknowledges this.
+This three-way interaction is used to ensure consistency between the states
+of the \KDS/ and the \TMA/.
+The \ansi/ draft does not require such behavior,
+and might profit from some finite-state analysis to ascertain unsafe
+(in terms of correctness) states which are reachable.

+\section{Introduction}
+Initially,
+a brief model of a user community employing a trusted mail service is
+introduced.
+Following this introduction,
+a prototype system is described which attempts to meet the needs of a user
+community.
+Finally,
+open issues are discussed,
+which are currently not satisfied by the prototype system or its model of
+operation.
+
+Two or more entities,
+called {\it users},
+wish to communicate in a {\it secure} environment.
+Depending on their available resources,
+different levels of security are possible.
+At the extreme,
+two parties with substantial resources may wish to communicate in a fashion
+which prevents any third parties,
+known as {\it adversaries},
+from observing their communication.
+At this level,
+not only is an adversary unable to capture the communication for analysis,
+but in fact, the adversary is unaware that any communication is occurring at
+all.
+In most applications,
+this level of security is prohibitively expensive.
+A more economic method is to translate messages into a form which is useless
+to an adversary and then to communicate those messages on an insecure medium.
+
+This latter method requires the two users to have some sort of {\it key}
+with which to ``lock'' the plaintext into ciphertext when transmitting,
+and then to ``unlock'' the ciphertext back into useful form when receiving.
+Hence, there are two central issues to deal with:
+\underbar{first},
+keys must be generated, distributed, and maintained in a secure fashion;
+and,
+\underbar{second},
+the keys must be ``intricate'' enough so that sense can't be made out of the
+ciphertext without knowledge of the key.
+The first part is handled by a {\it key distribution center} (\KDC/),
+which maintains a list of users and a set of keys for each pair of users.
+The second part relies on sophisticated encryption and decryption algorithms.
+It is beyond the scope of this paper to describe cryptographic techniques in
+detail.
+For a detailed survey of this area, the reader should consult \cite{VVoyd83}.
+
+\tagfigure{1}{The \MTS/ Model}{mtsmodel}
+In the context of our discussion (using the terminology of \cite{X.400}),
+the medium used to transport is supplied
+by a {\it message transport system} (\MTS/),
+which is composed of one or more {\it message transport agents} (\MTA/s).
+Usually,
+the entire \MTS/ is distributed in nature,
+and not under a single administrative entity;
+in contrast, an \MTA/ is usually controlled by a single administration and
+resides in a particular domain.
+At every end-point in the medium,
+a {\it user agent} (\UA/) acts on behalf of a user and interfaces
+to a local \MTA/.
+This model is briefly summarized in Figure~\mtsmodel.
+
+A message, in our context, consists of two parts:
+the {\it headers} and the {\it body}.
+The headers are rigorously structured;
+they contain addressing information and other forms useful to a \UA/.
+The body is freely formatted and is usually not meaningful to a \UA/.
+
+When a message is sent from one user to another,
+the following activities occur:
+The originating user indicates to the \UA/ the address of the recipient;
+the \UA/ then posts the message through a {\it posting slot} to an \MTA/,
+which involves a posting protocol in which the validity of the address
+and the syntax of the message are considered.
+Upon successful completion of the protocol,
+the \MTA/ accepts responsibility for delivering the message,
+or if delivery fails, to inform the originating user of the failure.
+The \MTA/ then decides if it can deliver the message directly to the
+recipient;
+if so, it delivers the message through a {\it delivery slot} to the
+recipient's \UA/,
+using a delivery protocol.
+If not, it contacts an adjacent \MTA/, closer to the recipient,
+and negotiates its transfer (using a protocol similar to the posting protocol).
+This process repeats until an \MTA/ is able to deliver the message,
+or an \MTA/ determines that the message can't be delivered.
+In this latter case,
+a failure notice is sent to the originating user.
+
+\tagfigure{2}{Mappings in the \MTS/ model}{mappings}
+It is important to note that there are two mappings which occur here.
+The first, which is performed implicitly by the originating user,
+maps the name of the recipient into the recipient's address;
+the second, which is performed explicitly by the \MTS/,
+maps the address of the recipient into a route to get from the originator's
+\MTA/ to the recipient's \MTA/.
+These mappings are depicted in Figure~\mappings.
+
+Obviously, there is no guarantee that the \MTS/ can be made secure,
+in {\it any} sense of the word.
+This is particularly true if it is under several administrations.
+Regardless of the number of administrations in the \MTS/,
+this problem quickly degenerates to a problem of
+Byzantine generals\cite{LLamp82}.
+Further, trying to secure each \MTA/ in the path that a message travels is
+equally questionable.
+
+\tagfigure{3}{Modifications to the \MTS/ model}{tmodel}
+To support secure communications in this environment,
+a new entity,
+the {\it trusted mail agent} (\TMA/) is introduced into our model.
+A solution is to have the \UA/ interact with this entity
+both when posting a message and when taking delivery of a message.
+The \UA/ first contacts a \TMA/ to encrypt the body of the message for the
+recipient,
+prior to pushing it through the posting slot.
+Upon receipt from the destination \MTA/,
+the \UA/ examines the message and contacts
+the \TMA/ to decipher the body of the message from the source.
+An overview of the relationship between the standard \MTS/ model
+and the augmentations made for the \trustedmail/ system is shown in
+Figure~\tmodel.
+
+To achieve these tasks,
+the \TMA/ interacts with a {\it key distribution service} (\KDS/),
+which manages keys between pairwise users.
+At this point, a third mapping takes place:
+the \UA/ must be able to map addresses into the identifier(s)
+by which the originator and recipient are known by the \TMA/ and \KDS/.
+These identifiers are known as \KDS/ IDs, or simply IDs.
+Usually, a fourth mapping also occurs,
+which maps the ID of a user into the name of a user.
+In our context,
+there is an exact one-to-one mapping between the name of a user and the ID
+of that user.
+In contrast,
+there may be a one-to-many mapping between the name of a user and
+that user's address in the \MTS/.
+Further, there are usually many different routes which a message may traverse
+when going from an originating user to a recipient user.
+
+The \TMA/ is said to be {\it trusted} because it can be relied on to perform
+only those actions specifically requested by the user.
+In the context of this paper,
+this means, given proper construction and maintenance of the \TMA/,
+that the software will communicate with the \KDC/ in some secure fashion to
+negotiate key relationships and that it will not disclose those key
+relationships to other parties.
+Furthermore,
+the body of mail messages exchanged between users which employ
+a trusted mail agent will be unintelligible to other parties.
+Finally,
+a recipient of a message receives authenticated information from the
+trusted mail agent as to the identify of the sender.
+
+Hence,
+when each user employs a \TMA/,
+end-to-end encryption occurs at the \UA/ level
+(to avoid any problems with malicious \MTA/s).%
+\nfootnote{Note that in the scope of this system,
+the end-points are the user agents, not the hosts they reside on.
+In fact,
+it may very well be the case that the user agent and the local message
+transport agent do not reside on the same host.}
+Any adversary listening in on the \MTS/,
+may observe messages,
+but make no sense out of them
+(other than rudimentary traffic analysis).
+Note, however,
+that since the medium itself is not secure,
+an adversary may still introduce new messages,
+corrupt messages,
+or remove messages,
+as they traverse the \MTS/.
+In the first two cases, however,
+the recipient would be suspicious
+because the adversary lacks the encrypting key employed by the source user.
+In the third case,
+the source user can retransmit the message after a suitable time.
+Of course,
+there is no built-in retransmission policy~---~this aspect depends on the
+user's sending mail and is beyond the scope of the system.
+
+It is important to understand the target community for the \trustedmail/ system
+described herein.
+In particular,
+the \TMA/ is intended for a commercial and not a military environment.
+This distinction is important,
+since it is the {\it fundamental} assumption of this paper that
+the latter community has much stricter requirements than the former.
+Because of this,
+the prototype system is able to make certain simplifying assumptions which
+permit it to operate in a mode which is less secure than military
+applications would permit.
+Although these issues are explored in greater detail at the end of the paper,
+for the moment recall that, like most qualities, trustedness is not absolute:
+there are varying degrees of trustedness,
+and as a system becomes more trusted,
+it becomes more expensive, in some sense, to operate and maintain.
+
+It is perhaps instructive at this point to consider why the introduction of a
+key distribution center is appropriate in this environment,
+and why the {\it fundamental} assumption that trusted mail agents do not
+directly communicate with each other is necessary.
+Although a user agent is able to converse with the local message transport
+agent in real-time,
+it is frequently not able to communicate with other user agents in real-time.
+Furthermore,
+considering the vast problems and overhead
+of trying to establish secure communications from ``scratch''
+(a problem far beyond the scope of this paper),
+it is would not be a good idea to try and communicate key relationships with
+other user agents,
+even if it were always possible to do so.
+In addition,
+by separating the trusted aspects of the message transport system from the
+system itself,
+many other advantages can be seen.
+These are presented in greater detail at the end of the paper.
+
+The discussion thus far has considered only a single recipient.
+In practice, a user might wish to send to several others,
+using a different key for each.
+Hence each copy of the message is encrypted differently,
+depending on the particular recipient in question.
+Note that this has the effect of {\it un-bundling} message transfer in the
+\MTS/,
+as advanced \MTA/s tend to keep only a single copy of the message for any
+number of recipients in order to save both cpu, disk, and I/O resources.
+
+For example,
+in some existing mail systems,
+if a message was sent to $n$ users on a remote system,
+then the $n$ addresses would be sent from the source \MTA/ to the remote \MTA/
+along with one copy of the message.
+Upon delivery,
+the remote \MTA/ would deliver a copy to each of the $n$ recipients,
+but the virtual wire between the source \MTA/ and the recipient \MTA/ was
+burdened with only one copy of the message.
+But in a secure environment,
+since a different key is used by the source user when communicating with each
+of the $n$ recipients,
+$n$ different messages will be posted with the local \MTA/,
+and the advantages of recipient bundling are lost.
+
+Along these lines however,
+private discussion groups may wish to avoid this problem by establishing
+access to a single ID for their use.
+In this case,
+a subscriber to the \KDS/ may actually have more than one ID,
+one for ``personal'' use and one for each discussion group.
+The appropriate ID is used when posting messages to the discussion group.
+Naturally the administrative policy for deciding who is allowed to use the
+\KDS/ ID of a discussion group is left to the moderator of the group.
+Observant readers will note that this vastly decreases the aspect of
+secure communications for the discussion group.
+This method is suggested as a compromise
+which permits the bundling of messages for multiple recipients
+to reduce \MTS/ traffic.
+The price is high however,
+as a compromise on behalf of {\it any} member of the discussion group
+compromises the entire group.
+For large discussion groups and a bandwidth limited \MTS/,
+this price may be worth paying.
+The prototype implementation of the \TMA/ supports multiple recipients but
+not multiple \KDS/ IDs.
+
+Having described this environment for communication,
+the designs of a \KDS/ and \TMA/ which form the heart of the \TTI/
+\trustedmail/ system are discussed.
+The prototype system was developed on a \vax/-11/780 running 4.2\bsd/ \unix/.
+The system is based on the \ansi/ draft\cite{FIKM}
+for financial key management,
+but diverges somewhat in operation
+owing to the differences between the electronic mail (CBMS)
+and electronic funds (EFT) environments.
+Note however that the \ansi/ data encryption algorithm\cite{DEA,FIPS46} is
+used in the current implementation.
+A public-key cipher system was not considered as the basis for the prototype
+since, to the authors' knowledge,
+an open standard for a public-key system has yet to be adopted by the
+commercial community.
+In contrast,
+the \ansi/ draft for financial key management appears to be receiving
+wide support from the commercial community.

+\section{The Key Distribution Service}
+The prototype version of the \KDS/
+was designed to provide key distribution services for
+user agents under both the same or different administrations.
+As a result,
+the means by which a trusted mail agent connects to a key distribution server
+is quite flexible.
+For example,
+the prototype system supports connections via
+standard terminal lines,
+dial-ups (e.g., over a toll-free 800 number),
+\unix/ pipes,
+and over TCP sockets\cite{IP,TCP}.
+In the interests of simplicity,
+for the remainder of this paper,
+a TCP/IP model of communication is used.
+Initially,
+a server on a well-known service host in the ARPA Internet community
+listens for connections on a well-known port.%
+\nfootnote{The term {\it well known} in this context means that the 
+location of the service is known {\it a priori} to the clients.}
+As each connection is established,
+it services one or more transactions over the lifetime of the session.
+When all transactions for a session have been made,
+the connection is closed.
+If the necessary locking operations are performed by the server
+to avoid the usual database problems,
+then more than one connection may be in progress simultaneously.
+Of course,
+a time-out facility should also be employed to prevent a rogue agent from
+monopolizing the key distribution server.
+
+Once a session has been started,
+the client (a.k.a.~\TMA/) initiates transactions with the server
+(a.k.a.~\KDS/).
+Each transaction consists of the exchange of two or three
+{\it cryptographic service messages} (\CSM/s):
+the client sends a request,
+the server attempts to honor the request and sends a response,
+and,
+if the server responded positively,
+the client then acknowledges the transaction.
+By exchanging these cryptographic service messages,
+the \KDS/ and the \TMA/ are able to communicate key relationships.
+Obviously, the relationships themselves must be transmitted in encrypted
+form.%
+\nfootnote{Otherwise an adversary could simply impersonate a \TMA/ and ask
+for the desired key relationships.
+Similarly, this also prevents an adversary from successfully impersonating a
+key distribution server.}
+Hence, not only are key relationships between two \TMA/s communicated,
+but key relationships between the \KDS/ and the \TMA/ are communicated as well.
+
+This leads us to consider the key relationships that exist
+between a \TMA/ and the \KDS/.
+A client usually has three keys dedicated for use with the server.
+The first is the {\it master key} (denoted MK),
+which has an infinite cryptoperiod, and is rarely used.
+This key is distributed manually.
+The second is the {\it key-encrypting key} (denoted KK),
+which has a shorter cryptoperiod.
+Whenever a KK is transmitted to the \TMA/,
+it is encrypted with the master key.
+The third is the {\it authentication key} (denoted KA),
+which is used to authenticate transactions that do not contain data keys
+(a count field is also used to avoid play-back attacks).
+Whenever a KA is transmitted to the \TMA/,
+it is encrypted with the key-encrypting key.
+When transactions contain keys,
+an associated count field is included to indicate the number of
+keys encrypted with the key-encrypting key used.
+Although not used by the prototype implementation,
+a production system would employ audit mechanisms to monitor usage histories.
+
+Currently four types of requests are honored by the \KDS/:
+two key relationship primitives, and two name service primitives.
+The type is indicated by the {\it message class} (MCL) of the first
+cryptographic service message sent in the transaction.
+As each message class  is discussed,
+the appropriate datastructures used by the \KDS/ are introduced.
+Space considerations prevent a detailed description of the information
+exchanged in each transaction.
+Appendix~B of this paper presents a short example of an interaction between
+the \KDS/ and a \TMA/.
+
+The first two requests are used to create (or retrieve) key relationships,
+and to destroy key relationships:
+
+The {\it request service initialization} (RSI) message class
+is used to establish a {\it key-encrypting key} (KK) relationship
+between the \TMA/ and another \TMA/,
+or between the \TMA/ and the \KDS/.
+As implied by the name,
+a key-encrypting key is used to cipher keys which are used to cipher data
+exchanged between peers.
+These other keys are called {\it data keys} (KDs).
+
+The {\it disconnect service message} (DSM) message class
+is used to discontinue a KK-relationship
+between the \TMA/ and another \TMA/,
+or between the \TMA/ and the \KDS/.
+This prevents keys which are felt to have been compromised,
+or are vulnerable to compromise,
+from receiving further use in the system.
+It should be noted that,
+owing to mail messages (not \CSM/s) in transit,
+a discontinued key relationship
+may be needed to decipher the key used to encipher a mail message.
+The prototype \KDS/ supports this capability.
+
+In addition to maintaining an MK/KK/KA triple for each \TMA/,
+the \KDS/ also remembers KK-relationships between \TMA/s.
+The reason for this stems from a fundamental difference between the
+electronic funds transfer and computer-based message system worlds.
+The \KDS/ assumes that no two arbitrarily chosen \TMA/s can communicate in
+real-time,
+and as a result,
+\TMA/s do not exchange cryptographic service messages.
+(See Appendix~C for a more detailed discussion.)
+This means that when a \TMA/ establishes a KK-relationship with another \TMA/,
+the former \TMA/ may start using the KK before the latter \TMA/ knows of the
+new KK-relationship.
+In fact,
+it is quite possible for a KK-relationship to be established,
+used,
+and then discontinued,
+all unilaterally on the part of one \TMA/.
+It is up to the \KDS/ to retain old cryptographic material
+(possibly for an indefinite period of time),
+and aid the latter \TMA/ in reconstructing KK-relationships as the need arises.
+Naturally,
+discontinued KKs are not used to encode any new information,
+but rather to decode old information.
+(Again, refer to Appendix~C for additional details.)
+
+The other two requests are used to query the directory service aspects of the
+key distribution server:
+
+The {\it request user identification} (RUI) message class
+is used to identify a subscriber to the \KDS/.
+Both  the \KDS/ and \TMA/ are independent of any underlying mail transport
+system (\MTS/).
+As a result,
+a subscriber to the \KDS/ is known by two unique attributes:
+a ``real-world'' name,
+and a \KDS/ identifier (ID).
+The user of a mail system,
+or the \UA/,
+is responsible for mapping an \MTS/-specific address
+(e.g., {\tx address@hidden)
+to the person associated with that maildrop
+(e.g., \eg{Marshall\ T.\ Rose}).
+When conversing with the \KDS/,
+the \TMA/ uses the \KDS/ ID of another user to reference that person's \TMA/.
+Since it is inconvenient to remember the IDs (as opposed to people's names),
+the \KDS/ provides the RUI message class to permit a \TMA/ to query the
+mapping between names and IDs.
+If the \KDS/ cannot return an exact match,
+it may respond with a list of possible matches
+(if the identifying information given was ambiguous),
+or it may respond with a response that there is no matching user.
+
+Finally,
+the {\it request identified user} (RIU) message class
+performs the inverse operation:
+given a \KDS/ ID, a ``real-world'' name is returned.
+This request is useful for disambiguating unsuccessful RUI requests
+and in boot-strapping a \TMA/.
+
+The \KDS/ maintains two directories:
+a private directory and a public directory.
+The private directory contains all information on all clients to the \KDS/.
+The public directory is a subset of this,
+and is used by the \KDS/ when processing RUI and RIU requests.%
+\nfootnote{In the prototype implementation,
+the two directories are, for the moment, identical.}
+As a result,
+certain clients of the \KDS/ may have unlisted IDs and names.
+
+\section{The Trusted Mail Agent}
+The prototype version of the \TMA/
+was designed to interface directly to the user agent in order to maximize
+transparency to the user.
+In present form,
+the \TMA/ is available as a load-time library under 4.2\bsd/ \unix/,
+although efforts are currently underway to transport the \TMA/ to a PC-based
+environment.
+
+The software modules which compose the \TMA/ contain a rich set of interfaces
+to the \KDS/.
+In addition,
+the \TMA/ manages a local database,
+so responses from the \KDS/ may be cached and used at a later time.
+In all cases,
+the \KDS/ is consulted only if the information is not present
+in the \TMA/ database,
+or if the information in question has expired (e.g., KK-relationships).
+This caching activity minimizes connections to the \KDS/.
+Although connections are relatively cheap in the ARPA Internet,
+substantial savings are achieved for PCs which contact the \KDS/ over a
+public phone network (dial-up) connection.
+
+The \TMA/ performs mappings between pairs of the following objects:
+user names, \KDS/ IDs, and \MTS/ addresses.
+The \TMA/ considers all trusted mail agents, including itself,
+as a user name, \KDS/ ID, and one or more \MTS/ addresses.
+Although the \TMA/ does not interpret addresses itself,
+in order to simplify mail handling,
+the \TMA/ remembers the relationship between these objects so the user enters
+this information only once.
+
+Initially,
+when a \TMA/ is booted,
+the user supplies it with the master key and the user's \KDS/ ID.
+Both of these quantities are assigned by the personnel at the key
+distribution center,
+and subsequently transmitted to the user via an alternate, bonded service.%
+\nfootnote{In this fashion,
+the problems of boot-strapping over an unsecure medium are avoided.}
+The \TMA/ connects with the \KDS/ and verifies its identity.
+From this point on,
+the \TMA/ manages its KK-relationships between the \KDS/ and other \TMA/s
+without user intervention.
+
+The current implementation of the \TMA/ assumes a ``general memo framework''
+in the context of the Standards for ARPA Internet Text Messages\cite{DCroc82}:
+\smallskip
+{\advance\leftskip by\parindent
+\item{1.} A message consists of two parts:
+the {\it headers} and the {\it body}.
+A blank line separates the headers from the body.
+
+\item{2.} Each (virtual) line in the headers consists of a keyword/value
+pair, in which the keyword is separated from the value by a colon (:).
+The headers are rigorously structured in the sense that they contain
+addressing and other information useful to a user agent.
+
+\item{3.} The body is freely formatted and must not be meaningful to a
+user agent.
+However, as will be seen momentarily,
+the body of encrypted messages must have an initial fixed format which the
+\TMA/ enforces.
+\smallskip}
+\noindent
+This format is widely called ``822'' after the number assigned to the
+defining report\cite{DCroc82}.%
+\nfootnote{Although an 822--style framework is employed by the \TMA/ prototype,
+the 822 \eg{Encrypted:} header is not currently present in encrypted messages.
+This is due to a design decision which assumes that nothing in the headers of
+a message is sacred to the transport system,
+and that ``helpful'' munging might occur at any time.
+In the real world, such helpfulness is often a problem.}
+
+To support the cipher activities described below,
+the \TMA/ contains internal routines to perform the following DES functions:
+electronic code book (ECB) for key encryption,
+cipher block chaining (CBC) for mail message encryption,
+checksumming (CKS) for mail message and \CSM/ authentication.
+Readers interested in these different modes of operation for the DES should
+consult \cite{FIPS81}.
+
+\subsection{Encrypting Mail}
+To encipher a message, the method used is a straightforward adaptation
+of the standard encrypting/authentication techniques
+(though the terminology is tedious).
+Consider the following notation:
+\smallskip
+{\advance\leftskip by\parindent
+\itemm $a_x(s)$ the checksum of the string $s$ using the key $x$
+(DEA~{\it checksumming} authentication)
+
+\itemm $a_{x+y}(s)$ the checksum of the string $s$ using the exclusive-or
+of the two keys $x$ and $y$
+
+\itemm $e_x(y)$ the encryption of the key $y$ using the key $x$
+(DEA~{\it electronic code book} encryption)
+
+\itemm $e_{x,y}(s)$ the encryption of the string $s$ using the key $x$
+and initialization vector $y$
+(DEA~{\it cipher block chaining} encryption)
+
+\itemm $h$ the headers of the message
+
+\noindent and,
+
+\itemm $b$ the body of the message
+\smallskip}
+\noindent
+For each message to be encrypted,
+a data key, initialization vector, authentication key (KD/IV/KA)
+triple is generated by a random process.
+(It goes without saying that the integrity of the system depends on the
+process being {\it random\/}).
+Then, for each user to receive a copy of the encrypted message,
+the following actions are taken:
+
+First, the headers of the message are output in the clear.
+Then, a {\it banner} string, $i$, is constructed and placed at the beginning
+of the body of the message:
+\example ENCRYPTED MESSAGE: TTI TMA\endexample
+which identifies the message as being encrypted by the \TTI/ \TMA/.
+Following the banner string is a structure, $m$,
+which takes on the syntax and most of the semantics of a cryptographic
+service message:
+$$\displayindent=\leftskip     \advance\displayindent by1.5\parindent
+    \halign{\hfil#/&   \enspace#\hfil\cr
+       MCL&    MAIL\cr
+       RCV&    rcvid\cr
+       ORG&    orgid\cr
+       IDK&    kkid\cr
+       KD&     $e_{kk}(ka)$\cr
+       KD&     $e_{kk}(kd)$\cr
+       IV&     $e_{kd}(iv)$\cr
+       MIC&    $a_{ka}(b)$\cr
+       MAC&    $a_{kd+ka}(m)$\cr
+}$$
+After this, the encrypted body is output, $e_{kd,iv}(b)$.
+In short, the entire output consists of
+$$h+i+m+e_{kd,iv}(b).$$
+
+The purpose of the structure $m$ is many-fold.
+The MCL field indicates the structure $m$'s type;
+currently only the type MAIL is generated and understood.
+The RCV and ORG fields identify the intended recipient of the message
+and the originator.
+The IDK field identifies the key-encrypting key, KK,
+used to encrypt the next two fields.
+The first KD field has the encrypted authentication key, KA,
+used to calculate the MIC of the plaintext of the body of the message.
+After the body of the message is deciphered, $a_{ka}(b)$ is calculated and
+compared to the value of the MIC field.
+Hence, the MIC field authenticates the message body.
+The second KD field has the encrypted data encrypting key, KD,
+which along with the encrypted initialization vector in the IV field
+was used to generate the ciphertext of the body.
+Finally, the MAC field authenticates the $m$ structure itself.
+The use of a data key, initialization vector, authentication key (KD/IV/KA)
+triple permits us to perform key distribution in a hierarchical fashion and
+allows the system to use a KK-relationship over a longer cryptoperiod
+without fear of compromise.
+
+The \TMA/ provides three primary interfaces to a \UA/ to send encrypted mail:
+the first takes a file-descriptor to a message
+and returns a structure $g$ (called a {\it group})
+describing the ciphertext version of the body
+(this structure contains a KD, IV, and KA generated at random,
+along with a file-descriptor to the plaintext headers,
+a file-descriptor to the ciphertext body,
+and the checksum of the plaintext body);
+the second takes a user entry (or \MTS/ address) and $g$,
+and returns a file-descriptor to the encrypted message
+for that user (or \MTS/ address);
+the third takes $g$ and performs clean-up operations.
+The chief advantage to this scheme of encryption
+is that if the message is to be sent to more than one recipient,
+then the MIC and the encrypted body need only be calculated once,
+since the KD, IV, and KA remain constant
+(only the KK's change with each recipient,
+hence for each copy of the encrypted message,
+only the structure $m$ need be re-calculated).
+
+There are, however, a few subtleties involved:
+\underbar{first},
+the \MTS/ usually accepts only 7--bit characters,
+so the encrypted text is exploded to consist of only printable characters;%
+\nfootnote{%
+As a rule, in all \CSM/s,
+when encrypted information is transmitted,
+it is exploded after encryption by the sender,
+and imploded prior to decryption by the receiver.}
+\underbar{second},
+since the \MTS/ may impose limits on the length of a line,
+each line of output is limited to 64~characters;
+and,
+\underbar{third},
+since the body may require trailing padding,
+during encryption
+one last unit of 8~bytes is written (and encrypted),
+naming the number of characters (presently, nulls) padded in the
+previous 8~bytes ($0\tdots7$).
+
+\subsection{Decrypting Mail}
+To decipher a message, the method is also straightforward:
+The headers are output in the clear.
+The banner string is essentially ignored,
+and the structure $m$ is consulted to identify the correct key-encrypting key.
+The \TMA/ checks to see if it knows of that KK.
+If not, it asks the \KDS/ to supply it.
+From that point,
+the KA, KD, and IV are deciphered.
+The $m$ structure is then authenticated.
+With the correct key,
+the remainder of the body is deciphered,
+and all except for the last 16~bytes are output.
+The last 8~bytes indicate how many of the previous 8~bytes should be output.
+So,
+the appropriate number of bytes is output,
+and the plaintext body is authenticated and compared to the MIC.
+Needless to say,
+as the body is deciphered,
+it is imploded back to 8--bit characters and lines are restored to their
+previous lengths.
+To indicate that the message was correctly deciphered,
+a new header of the form
+\example X-KDS-ID: orgid (originator's name)\endexample
+is appended to the headers of the message.
+Note that this provides an authentication mechanism.
+Note, further,
+that the \UA/ did not have to know the identity of the sender of the message.
+
+\section{Modifications to MH}
+\MH/ is a public domain \UA/ for \unix/,
+which is widely used in dealing with both a large number of electronic mail
+application and a large number of messages.
+Although this document does not intend to describe \MH/,
+parts of the system are described as they relate to the \TMA/.
+Readers interested in \MH/ should consult either the user's
+manual\cite{MRose85a} for a detailed description,
+or \cite{MRose85d} for a higher-level description.
+
+To modify \MH/ in order to make use of a \TMA/,
+three programs were changed (with a high degree of transparency to the user),
+and two new programs were introduced.
+
+In \MH/,
+when a user wishes to send a composed draft
+(which may be an entirely new message,
+a re-distribution of a message,
+a forwarding of messages,
+or a reply to a message),
+the user invokes the \pgm{send} program.
+This program performs some minor front-end work for a program called
+\pgm{post} which actually interacts with the \MTS/.
+A new option to the \pgm{send} and \pgm{post} programs,
+the \switch{encrypt} switch,
+is introduced.
+If the user indicates
+\example send\ -encrypt\endexample
+then \pgm{post} encrypts the messages it sends.
+
+When sending an encrypted message,
+\pgm{post} first checks that each addressee has a mapping to a \KDS/ ID
+during address verification.
+Then, instead of batching all addresses for a message in a single posting
+transaction,
+for each addressee,
+\pgm{post} consults the \TMA/ for the appropriately encrypted text and
+posts that instead.
+(Appendix~A discusses the reasons for this more fully.)
+Hence,
+assuming the user has established mappings between \MTS/ addresses
+and \KDS/ IDs,
+the \TMA/ does all the work necessary to encrypt the message,
+including contacting the \KDS/ as necessary.%
+\nfootnote{Once the \TMA/ establishes a connection to the \KDS/,
+it retains that connection until the \UA/ terminates.
+This is done to minimize connections to the \KDS/.
+In the context of \MH/,
+since the trusted mail agent is active over the lifetime of an invocation of
+a program such as \pgm{post},
+this means that the connection is terminated just before the program
+terminates.}
+
+In \MH/,
+when a user is notified that new mail has arrived,
+the \pgm{inc} program is run.
+As each message is incorporated into the user's message handling area,
+a scan (one-line) listing of the message is generated.
+
+By default,
+the \pgm{inc} program upon detecting one or more encrypted messages,
+after the scanning process,
+asks the \TMA/ to decipher the message,
+and if successful,
+scans the deciphered messages.
+This action can be inhibited with the \switch{nodecrypt} switch.
+Hence, if the user wishes to retain messages in encrypted form,
+\pgm{inc} can be told to note the presence of encrypted messages,
+but otherwise not to process them.
+By using the \MH/ user profile mechanism,
+\pgm{inc} can be easily customized to reflect the user's tastes.
+Again,
+the actions of the \TMA/ are transparent to the user.
+In fact,
+if encrypted mail is received from users unknown to the \TMA/,
+it queries the \KDS/ as to their identity prior to retrieving the
+KK-relationship.
+
+If \pgm{inc} fails to decrypt a message for some reason,
+or if \pgm{inc} was told not to decrypt a message,
+the \pgm{decipher} program can be used.
+This simple program merely deciphers each message given in its argument
+list.
+The \pgm{decipher} program can be given the \switch{insitu} switch,
+which directs it to replace the ciphertext version of the message with the
+plaintext version;
+or,
+the \switch{noinsitu} switch can be used indicating that the ciphertext
+version of the message should be left untouched and the plaintext version
+should be listed on the standard output.
+
+Finally,
+the \pgm{tma} program is used to manipulate the \TMA/ database,
+containing commands to boot the database,
+add new users to the database,
+and to establish mappings between addresses and users in the \TMA/ database.
+This program can also be used to disconnect KKs between other \TMA/s,
+and the KK/KA between itself and the \KDS/.
+
+Appendix~A of this paper contains a transcript of an \MH/ session.
+
+\section{Remarks}
+We now consider the merit of the system described.
+After presenting some of the basic strengths of the system
+and a few unresolved questions,
+the discussion centers on the simplifying assumptions made by the system,
+and how these can be defended in a non-military environment.
+
+\subsection{Strengths}
+It can be argued that the prototype system
+(and the augmented model in which it finds its basis)
+present many strengths.
+
+Perhaps the most important is the high-level of independence from the \MTS/
+enjoyed by the system.
+As a result,
+since the \TMA/ does not interact directly with the \MTS/,
+it can be made to be completely free from any \MTS/-specific attributes,
+such as naming, addressing, and routing conventions.
+Furthermore,
+when interfacing a \trustedmail/ system,
+no modifications need be made to the \MTS/ or local \MTA/.
+
+In addition to the systems-level advantage to this scheme,
+users of the system profit as well,
+since many disjoint \MTS/s can be employed by a user with a single \TMA/.
+This reduces the number of weaknesses in the system and allows a user to keep
+a single database of ``trusted'' correspondents.
+It should also make analysis and verification of the \TMA/ easier.
+
+Of course from the user-viewpoint,
+once the \TMA/ has been initially booted,
+all key management is automatic.
+Not only does this reduce the risk of compromise of cryptographic material
+(given proper construction and maintenance of the \TMA/),
+but it relieves the user of a tedious and error-prone task.
+
+Finally,
+although the \KDS/ described herein is used to support \trustedmail/,
+other applications which require key management,
+could employ the services offered by the key distribution center.
+
+\subsection{Open Questions}
+At present, there are many restrictions on the prototype implementation
+described.
+Some of these result from that fact that the implementation is a prototype
+and not a production system.
+Others deal with more fundamental issues.
+
+In terms of the \TMA/,
+the expiration delay for keys is hard-wired in;
+it should be user-settable.
+In the prototype version,
+the KK and KA with the \KDS/ are good for 2~days or 10~uses
+(whichever comes first),
+while a KK for use with another \TMA/ is good for 1~day or 5~uses.
+In actual practice,
+keys with long cryptoperiods might be good for 6~months or 100~uses,
+while keys with short cryptoperiods might be good for 1~month or 25~uses.
+The choice of actual values is an open question
+beyond the scope of prototype system.%
+\nfootnote{The current values were chosen by guess work.
+Although not necessarily technically sound,
+the small numbers were very good for debugging purposes.}
+In many respects, this issue is a classic trade-off:
+with relatively small cryptoperiods,
+an adversary has less chance of breaking a key,
+but with longer cryptoperiods less connections have to be made to the key
+distribution server.
+
+A fundamental issue,
+owing to differences between the EFT and CBMS environments,
+is that the \KDS/ implements only a subset of the \ansi/ draft
+and the semantics of certain operations have changed somewhat.
+It would be nice to unify the CBMS and EFT views
+of a {\it key distribution center}
+(in the former environment, the center is called a \KDC/,
+while in the latter environment, the center is known as a \CKD/).
+Appendix~C of this paper discusses the differences between the two
+perspectives in greater detail.
+
+At present,
+the relationship between errors in the \TMA/ and the posting process is an
+open question.
+For example,
+if an address doesn't have a mapping in the \TMA/ database,
+\pgm{post} treats this as an address verification error.
+This prevents the draft from being posted.
+The philosophy of the \UA/ is unclear at this point,
+with respect to how recovery should occur.
+A second area, also in question, deals with the way in which plaintext and
+ciphertext versions of a message are present in a system.
+Clearly, it is a bad idea to make both versions available,
+but since the \TMA/ doesn't try to concern itself with first party
+observation,
+there seems to be little possibility of preventing this behavior.
+The best that can be done,
+at this stage,
+is simply to choose a consistent policy that user's should attempt to adhere
+to.
+The software can help somewhat in implementing this policy,
+but it certainly can't circumvent the user.
+
+The prototype is built on the assumption that a single key
+distribution server is present.
+Since the \ansi/ draft\cite{FIKM} makes provisions for
+{\it key translation centers},
+the \trustedmail/ prototype should perhaps be made to operate in a more diverse
+environment.
+Until the issues become clearer,
+this remains open.
+
+Finally,
+for distribution lists,
+a large number of people would need to share the same \KDS/ ID.
+The current implementation doesn't support this.
+Each \TMA/ database is for a particular ID.
+A user with multiple IDs would need multiple databases,
+or the database should be re-organized.
+
+\subsection{Weaknesses}
+As pointed out earlier,
+this prototype system situates itself in a commercial, not military,
+environment.
+With respect to this decision,
+several aspects of the system are now discussed,
+which we feel are acceptable in a commercial environment,
+but which would be considered weaknesses in a military environment:
+
+\item{1.} Traffic Flow\hbreak
+The prototype \TMA/ makes no attempt whatsoever to prevent or confuse traffic
+analysis by augmenting traffic flow.
+
+\item{2.} The Database of \KDS/ Subscribers\hbreak
+Since information returned by the request user identification (RUI)
+and request identified user (RIU) MCLs are returned in the clear,
+this allows an adversary to ascertain subscribers to the \KDS/,
+and perhaps deduce some information about the system.
+Without knowledge of the master key however,
+an adversary could not impersonate a subscriber though.
+Still, in the military sense, this is a weakness.
+However,
+all this assumes that the database maintained by the \KDS/ accurately
+reflects the real-world.
+
+\item{3.} Multiple Recipients\hbreak
+It is possible, though not proven to the authors' knowledge,
+that the scheme used to avoid encrypting the body of a message more than once
+for multiple recipients might permit one of the recipients who is also an
+adversary to compromise the key relationship between the sender and another
+recipient.
+
+\item{} The scenario goes like this:
+When a message is being prepared for encryption,
+a single KD/IV/KA triple is generated to encrypt the body.
+Since the sender has a different key relationship with each recipient,
+each message sent is different, since the structure $m$ depends not only on
+the KD/IV/KA triple but also on the key relation between the sender and a
+particular recipient.
+Now suppose that one of the recipients, $r_1$,
+in addition to receiving the copy of the message meant for him/her also
+intercepts a copy of the message destined for another recipient, $r_2$.
+At this point,
+the recipient $r_1$ has both the plaintext and ciphertext version of the body,
+the plaintext version of the KD/IV/KA triple,
+and the ciphertext version of the KD/IV/KA triple that was generated using
+the key relationship between the sender and the recipient $r_2$.
+The question is:
+can $r_1$ now deduce the key relationship between the sender and $r_2$?
+
+\item{} If so, then the way that the \TMA/ attempts to minimize the use of
+encryption resources is a weakness.
+But, even if this is possible,
+given relatively short cryptoperiods for key relationships between \TMA/
+peers,
+this becomes a non-problem.
+
+\item{4.} Discussion Groups\hbreak
+As discussed earlier,
+the proposed method of associating a single \KDS/ ID with the membership of a
+discussion group does introduce a significant weakness for the security of
+messages sent to the discussion group.
+Since the \TMA/ does not assume a general broadcast facility,
+it appears that there are no good solutions to the problem of discussion
+group traffic.
+Of course,
+it is easy enough to simply send to each member of the group.
+
+\item{} For the sake of argument,
+let's assume that the discussion group has $n$ members.
+Now,
+since a different key relationship would exist between the sender and
+each of the $n$ recipients,
+the structure $m$ would be different for each recipient
+and so a different message would have to be sent to each recipient.
+To make matters worse,
+if one rejects the way the \TMA/ handles multiple recipients,
+not only does the \MTS/ get burdened with $n$ different messages,
+but the sender's \TMA/ gets burdened by having to encrypt
+the body of the message $n$ times.
+For meaningful values of $n$ (say on the order of~500, or even~25),
+the amount of resources required for any trusted discussion group are simply
+too costly.
+
+\subsection{Compromises, Compromises}
+Each of the possible weaknesses discussed above represent a compromise
+between the expense of the system and the level of security it can provide.
+
+The first two areas, if addressed by the \TMA/,
+could result in much less background information being available to an
+adversary.
+In an application where it is important that an adversary not know who is
+talking to whom,
+or who can talk at all,
+this is very important.
+It is the authors' position that in the commercial environment,
+this issue is not paramount.
+By ignoring the issue of traffic flow,
+the \TMA/ has a lot less work to do and the \MTS/ is kept clear of
+``useless'' messages.
+By keeping the information returned by the RUI and RIU MCLs in the clear,
+the complexity of the \TMA/ is significantly reduced.
+
+The second two areas, if addressed by the \TMA/,
+could result in a lesser probability of traffic being deciphered by an
+adversary.
+Regardless of the application,
+this is always extremely important.
+However,
+the authors' feel that the compromise made by the \TMA/ in these two issues
+is not substantial,
+and does not result in an explicit weakness when a message is sent to
+multiple recipients
+(note that when there is only a single recipient of a message,
+these two policies can not introduce weaknesses).
+In return, efficient use can be made of both the \MTS/ and the \TMA/ when
+messages are being sent to multiple recipients.
+Given scarce resources or large numbers of recipients,
+this approach may prove to be quite winning.
+
+Of course, much work remains to be done to prove the success of the \TMA/ in
+all four of these areas.

+\centerline{\sc Abstract}
+{\rightskip=0pt\narrower\narrower
+\noindent
+The design of the \TTI/ prototype Trusted Mail Agent (\TMA/) is discussed.
+This agent interfaces between two entities:
+a key distribution center (\KDC/) and a user agent (\UA/).
+The \KDC/ manages keys for the encryption of text messages,
+which two subscribers to a key distribution service (\KDS/) may exchange.
+The \TMA/ is independent of any underlying message transport system.
+
+\lp
+Subscribers to the \KDC/ are known by unique identifiers,
+known as IDs.
+In addition to distributing keys,
+the \KDC/ also offers a simple directory lookup service,
+in which the ``real-world'' name of a subscriber may be mapped to an ID,
+or the inverse mapping may be performed.
+
+\lp
+This document details three software components:
+\underbar{first},
+a prototype key distribution service,
+which has been running in a TCP/IP environment since December, 1984;
+\underbar{second},
+a prototype trusted mail agent;
+and, 
+\underbar{third},
+modifications to an existing \UA/,
+the Rand \MH/ Message Handling system,
+which permit interaction with the prototype \TMA/.

+The \MH/ system described herein is based on the original Rand \MH/ system.
+It has been extensively developed (perhaps too much so) by Marshall Rose and
+John Romine at the University of California, Irvine.
+Einar Stefferud, Jerry Sweet, and Terry Domae provided numerous suggestions
+to improve the UCI version of \MH/.
+
+Parts of this document are taken from a Rand tutorial \cite{SPayn85} by
+Sue Payne.

+
+\section{Scope}
+This document assumes that you have no knowledge of \MH/.
+However, to use \MH/ you should have some familiarity with the \unix/ 
+operating system,
+particularly with the way commands are given,
+how files are named,
+the jargon (e.g. {\it shell}, {\it argument}, {\it home directory},
+{\it pathname\/}),
+and how to use a text editor (such as \pgm{ex}, \pgm{vi}, or \pgm{emacs\/}).
+
+This tutorial covers only basic material.
+For additional information about \MH/,
+consult the {\it User's Manual} \cite{MRose85a}.
+Other documents of possible interest to you include
+{\it The UCI BBoards Facility} \cite{MRose84}
+and
+the {\it MH Administrator's Guide} \cite{MRose85b}.
+
+\section{How To Use This Tutorial}
+Different typefaces and symbols are used in this document to denote the
+kinds of things you (the user) must type on your keyboard.
+\smallskip
+{\advance\leftskip by\parindent
+\item{1.} The names of programs are given in {\it text italics}:
+\smallskip\hskip 1in \pgm{comp}\smallskip
+\item{2.} Arguments to programs are given in {\tt typewriter style},
+delimited by single-quotes:
+\smallskip\hskip 1in \arg{msgs}\smallskip
+\item{3.} \unix/ pathnames are given in {\sl slanted roman}:
+\smallskip\hskip 1in \file{/usr/uci/}\smallskip
+\item{4.} Text giving a full example is presented in {\tt typewriter style}:
+\example comp\ -editor\ vi\endexample
+The ``\hbox{\tt\char`\ }'' glyph % (visible space glyph)
+is used to indicate an explicit space (the kind you make with the
+space bar on your keyboard).
+\smallskip}
+
+\section{Introduction}
+With \MH/ you can send messages to other people on your system
+and read messages that other people send to you.
+Depending on how things have been set up on your system,
+it may be possible for you to send messages to people on remote systems.
+You can also reply to messages that you have received,
+review them,
+organize them in {\it folders},
+and delete them.
+
+\MH/ differs from other mail programs in that it is composed of many
+small programs instead of just one very large program.
+Among new users this sometimes causes some confusion
+along the lines of ``what program do I run?''
+With \MH/, you use the shell to invoke one program at a time.
+This means that when you handle mail,
+the entire power of the shell is at your disposal
+in addition to the facilities that \MH/ provides.
+In the beginning, this may not make much sense or may not seem important.
+However, we have found that as new users of \MH/ gain experience, 
+they find this style of interface to be very useful.
+
+\section{Summary}
+The most minimal list of \MH/ commands that you can get by with is:
+\smallskip
+{\advance\leftskip by\parindent
+\item{\pgm{inc}}       - incorporate mail (get new mail)
+\item{\pgm{show}}      - show the first message
+\item{\pgm{next}}      - show the next message
+\item{\pgm{prev}}      - show the previous message
+\item{\pgm{comp}}      - compose a new message to send
+\item{\pgm{repl}}      - reply to a received message
+\smallskip}
+\pgm{Comp} and \pgm{repl} give enough prompting possibly to get you along.
+However, it is suggested that you take the time to peruse this
+tutorial before leaping into things.
+
+\section{Messages and Folders}
+A message takes the form of a memorandum,
+and is composed of two major parts:
+a {\it header},
+which contains such information as
+\eg{To} and \eg{From} addresses, \eg{Subject}, \eg{Date}, etc.;
+and the {\it body},
+which is the actual text of the message.
+Each {\it component} in the header starts with a keyword followed by
+a colon and additional information.
+For example, in the message:
+\example
+    Date: 10 Oct 84 17:41:14 EDT (Wed)\\
+    To: address@hidden
+    Subject: UCI Software Talk\\
+    From: UCI Portal (agent: Marshall Rose) <address@hidden>\\\\
+    This is the text.
+\endexample
+there are four header items, and one line of text in the body.
+Note that a blank line separates the body from the headers.
+
+\MH/ stores a message as an ordinary file in a \unix/ directory.
+This directory is called a {\it folder}.
+If you choose to keep and organize your messages,
+you may create as many folders as you wish.
+There is no limit as to the number of messages in a folder.
+Typically messages are numbered from~1 up.
+All of your personal folders,
+along with some other information that \MH/ needs to know,
+are kept in a special directory called \file{Mail} under your home directory.
+Normally, \MH/ manages these files and directories automatically,
+so you needn't muck around with them directly unless you really want to.
+
+You won't have any folders until somebody sends mail to you, as a rule.
+If you are anxious to try out \MH/, but no one has sent you mail yet,
+try sending mail to yourself to start out with.
+
+\section{Reading New Mail}
+When you are notified that you have mail (usually when you log in),
+perhaps with the message
+\example You have mail.\endexample
+then you know that messages are waiting in your {\it maildrop}.
+To read these messages, you first have to {\it incorporate} the mail
+into your ``in-box'' by typing the command:
+\example inc\endexample
+This incorporates the new mail from your mail drop to your in-box,
+which is a folder named (naturally enough) \arg{+inbox}.
+As \pgm{inc} incorporates your new mail,
+it generates a {\it scan listing} of the mail:
+$$\vbox{\tenpoint\tx\halign{\hfil#&#\hfil&&    \quad#\hfil\cr
+\noalign{\noindent Incorporating new mail into inbox...\medskip}
+2&+&   10/10&  WESTINE\%USC-ISIF&      RFC 916 Now Available&
+                                       <<A new Request for Co\cr
+3&&    10/10&  G B Reilly&             Gosling EMACS manual&
+                                       <<Marshall, I am lookin\cr
+4&&    10/11&  WESTINE\%USC-ISIF&      Internet Monthly Report&\cr
+}}$$
+Each time \pgm{inc} is invoked,
+any new messages are added to the end of your \eg{+inbox} folder.
+
+To read the first message,
+use the \pgm{show} command:
+\example show\endexample
+This displays the current message.
+To read each subsequent message,
+use the \pgm{next} command:
+\example next\endexample
+If you want to back up,
+the command \pgm{prev} shows the previous message.
+Another way to read your messages is to name them all at once:
+\example show\ all\endexample
+This command displays them all, one after the other.
+The \arg{all} argument to \pgm{show} above might also be replaced
+with \arg{next} or \arg{prev}, as in
+\example
+    show\ next\\
+    show\ prev
+\endexample
+which are respectively equivalent to the \pgm{next} and \pgm{prev}
+commands.
+
+If you have had occasion to type \pgm{inc} more than once, then
+you will find that \eg{show\ all} is showing not only the new messages,
+but also the old messages that you've already seen.
+Therefore, you might find it better to use
+\example show\ cur-last\endexample
+instead.
+This command displays messages from the current message (\arg{cur})
+to the last message (\arg{last}).
+Each time \pgm{inc} is invoked, it makes the first new message
+the current message.
+It should be noted here that the name \arg{all} given in a previous
+example is equivalent to the {\it message range} \arg{first-last},
+where \arg{first} is the name of the first message in \arg{+inbox}.
+Also, \eg{show} by itself is equivalent to
+\example show\ cur\endexample
+
+As mentioned earlier,
+with the \unix/ shell as your interface to \MH/,
+it becomes easy to list a message on a line printer or to another file.
+For example,
+\example show\ all\ |\ lpr\endexample
+lists all the messages in the current folder to the line printer.
+
+To summarize, the preceding has introduced these important concepts:
+{\it folders} (in particular, the \arg{+inbox} folder),
+{\it messages},
+{\it message names} (e.g. \arg{prev}, \arg{next}, \arg{cur}, \arg{last}),
+and {\it message ranges} (e.g. \arg{cur-last}, \arg{all}).
+More will be said about folders and messages in succeeding sections.
+
+\section{Sending Messages}
+To send a message, you compose a message {\it draft},
+either by replying to a message that someone sent to you,
+or by creating a draft from scratch.
+The \pgm{send} command is used {\bf after} completing the final draft
+of a message, 
+in the same way that you mail a paper letter only after you are finished
+writing it.
+This is a common source of confusion among new \MH/ users who
+may have had experience with other mail systems.
+
+This section discusses how to originate messages
+and how to reply to messages that were previously received,
+along with a word or two about addresses.
+
+\subsection{Originating Messages}
+To create a message draft from scratch,
+use the \pgm{comp} program.
+You will be prompted for the header components
+and then the body of the message.
+If you make a mistake, you may correct it later with a text editor.
+The draft will be sent only if you give an explicit \pgm{send} command,
+so you do not have to worry about the draft getting away from you
+prematurely.
+
+To start, you simply type:
+\example comp\endexample
+
+{\bf To:}
+First, the prompt \arg{To:} appears.
+Here you type the address of the person to whom you wish the message sent.
+If this person is on the same computer system as you,
+then that person's login ID should serve as the address
+(e.g. \arg{mrose} or \arg{jsweet}).
+
+Here we digress briefly to discuss addresses.
+A full discussion of addresses is beyond the scope of this
+tutorial, but it should be mentioned that there are other
+kinds of addresses besides login IDs.
+To send messages to people on remote systems, 
+the usual way is to type address@hidden in the \arg{To:} component,
+as in address@hidden
+Examples of \arg{host} names at UCI include
+\arg{uci-icsa},
+\arg{uci-icse},
+and \arg{uci-cip1}.
+Upper and lower case letters may be used interchangeably.
+Sometimes a person's last name (e.g. \arg{Rose}, \arg{Sweet}) can be used
+instead of a login ID,
+but this cannot be relied upon in a world without unique surnames.
+
+{\bf cc:}
+After you have given an address to the \arg{To:} prompt, 
+you are prompted for the \arg{cc:}
+(``carbon copy''--an archaism)
+address.
+It is customary, but not required, to put your own address
+here so that you get a copy of the message when it is sent.
+
+To put more than one address in the \arg{To:} and
+\arg{cc:} components,
+just use a comma (``,'') between each address on a line.
+
+{\bf Subject:}
+The third prompt is for the \arg{Subject:} component.
+Here a line of any descriptive text will do.
+Once you have typed a line of text, a dashed line is printed,
+and you are then expected to type the body of the message.
+End the body with EOT (usually CTRL-D).
+
+An example of a complete message draft, as it appears on your screen,
+might be:
+\example
+    To: News\\
+    cc: farber, mrose\\
+    Subject: UCI Software Talk\\
+    --------\\
+    A presentation on the UCI software suite, including\\
+    the Rand/UCI Mail Handling System (MH), will be given\\
+    in CS220 on October 31st at 2:30 PM.  Refreshments\\
+    will be served afterward.\\\\
+    /mtr\\
+    \^{}D
+\endexample
+(The ``\^{}D'' does not appear in the draft.)
+
+At this point, you are asked
+\example What\ now?\endexample
+This is known as being at \whatnow/ level.
+For now, there are probably only four options that will interest you:
+\smallskip
+{\advance\leftskip by\parindent
+\item{\pgm{edit}} - edit the draft
+\item{\pgm{list}} - list the draft on your screen
+\item{\pgm{quit}} - quit, without sending the draft
+\item{\pgm{send}} - send the draft, then quit
+\medskip}
+\noindent
+All of these options take various arguments,
+but only \pgm{edit} really needs an argument.
+
+{\bf Edit:}
+The \pgm{edit} option will let you edit the draft before sending it.
+If your favorite text editor is \pgm{vi},
+then you would use the \pgm{edit} option as:
+\example edit\ vi\endexample
+Just specifying \pgm{edit} with no argument
+will only let you append text to the body of the
+message draft.
+Another editor (e.g. \pgm{vi}, \pgm{ex}, \pgm{emacs\/})
+should really be run to finish the draft up.
+When you leave the editor, you will come back to the \whatnow/ level,
+where you can re-edit the draft, send it, list it, or simply quit
+without sending the draft at all.
+
+Caution: while in the editor,
+you should not delete colons in the headers
+or change the spelling of \arg{To:}, \arg{cc:}, or \arg{Subject:};
+and do not leave blank lines between these lines.
+Feel free to change the addresses that you typed previously,
+or to add these lines if they are missing.
+Do not delete the dashes that separate the header lines from
+the text of the message.
+You should not add additional header lines unless you understand
+precisely what you are doing.  
+This means particularly that you should not type or fill in a \arg{From:}
+line.
+When the message is sent, the system automatically adds this line.
+Also, you should not type a \arg{Date:} line in the header.
+When the message is sent, the system automatically adds the current
+date and time.
+
+{\bf Quit:}
+If you \pgm{quit} without sending the draft,
+the draft is saved in a file called \file{Mail/draft} under your
+home directory.
+This file can be recalled later using the \arg{-use} argument
+to \pgm{comp}:
+\example comp\ -use\endexample
+The \whatnow/ level will permit you to do further editing
+and to send the final draft when you are ready.
+
+{\bf Send:}
+When it is time to send the draft on its way,
+use the \pgm{send} option by itself.
+If there are any problems with the draft 
+(for example,
+if one or more of the people whom you specified in the \arg{To:} and \arg{cc:}
+components do not exist)
+then you will be notified at this time.
+
+\subsection{Replying to Messages}
+To reply to a message,
+use the \pgm{repl} command.
+For example,
+\example repl\endexample
+creates a reply to the current message.
+You may also reply to a specific message (other than the current one)
+by giving a {\it message number} (e.g. \arg{1}, \arg{4}, etc.)
+or a {\it message name} (e.g. \arg{first}, \arg{last}, \arg{prev}):
+\example repl\ prev\endexample
+We haven't really introduced message numbers yet.
+They will be discussed in the next section.
+
+The process of replying to a message is very similar to composing
+a message from scratch (see the previous section),
+but \pgm{repl} conveniently constructs and displays the header
+of the reply draft for you.
+You need only type in the text of the reply.
+An EOT (usually CTRL-D) indicates that you are done typing.
+If you make a mistake, you may correct it later with a text editor.
+The draft will be sent only if you give an explicit \pgm{send} command,
+so you do not have to worry about the draft getting away from you
+prematurely.
+
+An example of a complete reply draft, as it appears on your screen might be:
+\example
+    To: MRose\\
+    cc: JSweet\\
+    Subject: Re: UCI Software Talk\\
+    In-reply-to: Your message of 10 Oct 84 18:15:08 PDT (Wed).\\
+    --------\\
+    I'll be there.\\
+    -jns\\
+    \^{}D      
+\endexample
+(The ``\^{}D'' does not appear in the draft.)
+
+At this point, you are asked
+\example What\ now?\endexample
+This is known as being at \whatnow/ level.
+Refer to the previous section regarding how to edit,
+display, or send the draft at this point.
+
+As with \pgm{comp}, 
+if you \pgm{quit} without sending the reply draft,
+the draft is saved in a file called \file{Mail/draft} under your
+home directory.
+This file can be recalled later using the \arg{-use} argument
+to \pgm{comp}:
+\example comp\ -use\endexample
+The \whatnow/ level will permit you to do further editing
+and to send the final draft when you are ready.
+
+\section{Scanning Messages}
+The scan listing created by \pgm{inc} shows the {\it message number},
+the date on which the message was sent,
+the sender,
+and the subject of the message.
+If there is sufficient space remaining on the line,
+the beginning of the text of the message is displayed as well,
+preceded by two left angle brackets (``{\tenpoint\tx$<<$\/}'').
+An example of a scan listing is:
+$$\vbox{\tenpoint\tx\halign{\hfil#&#\hfil&&    \quad#\hfil\cr
+1&+&   10/10&  WESTINE\%USC-ISIF&      RFC 916 Now Available&
+                                       <<A new Request for Co\cr
+2&&    10/10&  G B Reilly&             Gosling EMACS manual&
+                                       <<Marshall, I am lookin\cr
+3&&    10/11&  WESTINE\%USC-ISIF&      Internet Monthly Report&\cr
+}}$$
+Note that all messages have message numbers.
+
+To generate your own scan listing, use the \pgm{scan} program.
+Typing simply
+\example scan\endexample
+will list all the messages in the current folder.
+To scan a subset of these messages,
+you can specify the numbers of the messages that you consider interesting,
+e.g.,
+\example scan\ 2\ 3\endexample
+Message names may be specified in addition to discrete message numbers.
+The built-in message names recognized by \MH/ are:
+\smallskip
+{\advance\leftskip by\parindent
+\item{\underbar{all}:} all messages in the folder (\arg{first-last})
+\item{\underbar{first}:}       the first message in the folder
+\item{\underbar{last}:}        the last message in the folder
+\item{\underbar{prev}:}        the message immediately before the current 
message
+\item{\underbar{cur}:} the current message
+\item{\underbar{next}:}        the message immediately after the current 
message
+\medskip}
+\noindent
+
+Message ranges may be specified in addition to discrete message numbers
+or names by separating the beginning
+and final message numbers with a dash (``-'').
+For example,
+\example scan\ 5-10\endexample
+scans messages~5 through~10 inclusive.
+A range of messages may also be specified by separating a beginning
+message number and a relative number of messages with
+a colon (``:'').
+For example,
+\example scan\ last:3\endexample
+scans the last three messages in the folder.
+Similarly,
+\example scan\ first:3\endexample
+scans the first three messages in the folder;
+\example scan\ next:3\endexample
+scans the next three messages;
+\example scan\ cur:3\endexample
+scans the three messages beginning from the current message;
+\example scan\ 100:4\endexample
+scans four messages beginning from message number 100.
+
+To summarize, the important concepts that have been discussed
+in the section are:
+{\it message ranges},
+{\it message numbers},
+and {\it message names}.
+When an \MH/ command is described as taking a \arg{msg} argument,
+it accepts either a message name or a message number.
+Most \MH/ commands are described as taking \arg{msgs} arguments,
+meaning that more than one message or message range is accepted.
+
+\section{Deleting Messages}
+To delete a message, use the \pgm{rmm} program.
+By default, \pgm{rmm} deletes the current message,
+but you can give \pgm{rmm} a list of messages to be removed as well.
+There is no corresponding ``\pgm{unrmm}'' program,
+but clever users with a need will find out how to change the way \pgm{rmm}
+works so that it simply moves messages to another folder
+(say, \arg{+wastebasket}).
+
+\section{Filing Messages}
+The possibility of having folders other than \eg{+inbox} has been mentioned
+previously.
+The methods for moving messages between folders and manipulating folders
+are discussed here.
+
+The \pgm{refile} command moves messages from a {\it source folder} to one or
+more {\it destination folders}.
+By default, the current message is moved from the {\it current folder} 
+(typically \arg{+inbox}) to another folder specified as an
+argument to \pgm{refile}.
+For example,
+\example refile\ +todo\endexample
+moves the current message from the current folder to the folder \eg{+todo}.
+To move messages from a folder other than the current folder,
+use the \switch{src +folder} switch, as in
+\example refile\ -src\ +todo\ last\ +save\ +notes\endexample
+which moves the last message in the \eg{+todo} folder to the folders
+\eg{+save} and \eg{+notes}.
+Note that this operation is a {\it move}, not a {\it copy};
+it removes the message from the source folder.
+To keep a copy in the source folder as well, use the \switch{link} switch
+\example refile\ -link\ -src\ +todo\ last\ +save\ +notes\endexample
+
+Whenever a folder argument is given to an \MH/ command,
+that folder becomes the {\it current folder}.
+To find out which folder is current, use the command
+\example folder\endexample
+The \pgm{inc} command sets the current folder back to \arg{+inbox}
+by default.
+To find out about all of a user's folders, use the command
+\example folders\endexample
+Since folders can contain other folders,
+the command
+\example folders\ -recurse\endexample
+will recursively examine each folder for you.
+
+To set the current folder, without doing anything else,
+use the \pgm{folder} program with a folder argument.
+Hence,
+\example folder\ +inbox\endexample
+makes \eg{+inbox} the current folder.
+
+After a using \pgm{rmm} and \pgm{refile} on a folder a number of times,
+there tend to be gaps in the numbering sequence.
+To compress the numbers for the all messages in a folder,
+use
+\example folder\ -pack\endexample
+
+\section{The Profile}
+You can customize the \MH/ environment by editing your \profile/ file.
+Although there are lots of options,
+here are the most useful:
+\smallskip
+{\advance\leftskip by\parindent
+\item{\underbar{Editor}:} lists the default editor that \pgm{comp} and
+\pgm{repl} should use.
+The default is
+\example editor:\ prompter\endexample
+but another editor might be preferred.
+
+\item{\underbar{{\it editor}-next}:} lists the editor that should be used
+after the last edit with {\it editor}.
+Hence, if you have a profile entry
+\example prompter-next:\ vi\endexample
+after editing a draft with \pgm{prompter},
+and being at \whatnow/ level,
+you could say \eg{edit} (instead of \eg{edit vi})
+to continue to edit the draft with \pgm{vi}.
+
+\item{\underbar{Msg-Protect}:}
+Whenever \MH/ creates a message (for example, with \pgm{inc\/}),
+this is the octal protection mode that the message is created with.
+The default is
+\example Msg-Protect:\ 644\endexample
+This protection mode permits all other users on the system to read
+your messages.
+To maintain privacy, the mode 600 should be used.
+Note that changing the mode in the profile does not change the modes
+of messages that have been created already.
+Use the \unix/ command \pgm{chmod} to change the modes of your
+existing messages.
+
+\item{\underbar{Folder-Protect}:}
+Whenever \MH/ creates a folder (for example, with \pgm{refile\/}),
+this is the octal mode that the folder is created with.
+The default is
+\example Folder-Protect:\ 711\endexample
+This mode permits other users on the system to make access to
+specific messages in your folders.
+To maintain stricter privacy, the mode 700 should be used.
+
+\item{\underbar{{\it program\/}}:}
+Each \MH/ program that reads user's \profile/ file
+looks for an entry beginning with its own
+name to determine its initial defaults.
+For example,
+if you want the default editor for \pgm{repl} to be \pgm{emacs},
+the line
+\example repl:\ -editor\ emacs\endexample
+is sufficient.
+Command line arguments tend to override profile settings.
+Given the profile setting for \pgm{repl} above,
+if you invoked \pgm{repl} with
+\example repl\ -editor\ vi\endexample
+\pgm{repl} would use the \pgm{vi} editor instead
+of \pgm{emacs}.
+
+\item{\underbar{signature}:}
+When \MH/ posts mail for you,
+it looks for this profile entry for your ``real world'' name.
+For example,
+\example signature:\ Marshall\ Rose\endexample
+The contents of the \eg{signature:} entry in the profile should be a simple
+phrase, with no embedded periods (e.g. ``Marshall T.~Rose'').
+\medskip}
+\noindent
+Note that your profile resembles the header portion of a message.
+Be sure that it is properly formatted by placing a colon after each entry
+name,
+and keep each entry on a single line.
+
+\section{Conventions}
+Now let's summarize the conventions that \MH/ programs use:
+\smallskip
+{\advance\leftskip by\parindent
+\item{1.} Any \MH/ command that deals with messages can be given a
+\arg{+folder} argument to say which folder to use.
+However, only one \arg{+folder} argument may be given per command
+in most cases.
+
+\item{2.} If an \MH/ command accepts a \arg{msgs} argument,
+then any number of messages can be given to the command.
+The \MH/ command will expand all the ranges and process each message,
+starting with the lowest numbered one and working its way to the message with
+the highest number.
+
+\item{3.} If an \MH/ command accepts a \arg{msg} argument,
+then at most one message can be given.
+
+\item{4.} Switches (options) to \MH/ commands start with a dash.
+Unlike the standard \unix/ convention,
+each switch consists of more than one character,
+for example \switch{header}.
+To minimize typing,
+only a unique abbreviation of the switch need be typed;
+thus for \switch{header}, \switch{hea} is probably sufficient,
+depending on the other switches accepted by the command.
+
+\item{5.} All \MH/ commands have a \switch{help} switch,
+which {\it must} be spelled out fully.
+When an \MH/ command encounters the \switch{help} switch,
+it prints out the syntax of the command,
+the switches that it accepts,
+and version information.
+In the list of switches,
+parentheses indicate required characters.
+For example,
+all \switch{help} switches will appear as \switch{(help)},
+indicating that no abbreviation is accepted.
+
+\item{6.} Many \MH/ switches have both on and off forms,
+such as \switch{format} and \switch{noformat}.
+In these cases,
+the last occurrence of the switch on the command line determines the setting
+of the option.
+
+\item{7.} All \MH/ commands that read your \MH/ profile operate the
+same way:
+\underbar{first},
+the profile is consulted for an entry matching the name with which
+the command was invoked;
+\underbar{second},
+if such an entry was found,
+then the command immediately uses the arguments listed;
+\underbar{third},
+any arguments on the command line are then interpreted.
+Since most switches have both on and off forms,
+it's easy to customize the default options for each \MH/ command in the
+\profile/,
+and to override those defaults on the command line.
+\smallskip}
+
+\section{Online Documentation}
+Each \MH/ program has its own \unix/ manual entry.
+For example, to get information about \pgm{comp},
+type
+\example man\ comp\endexample
+The manual entry for \man mh(1) lists all \MH/ commands,
+while the manual entry for \man mh-chart(1) lists the syntax and switches for
+all \MH/ commands.
+
+In addition,
+here are a few other manual entries might be found useful:
+\smallskip
+{\advance\leftskip by\parindent
+\item{\man mh-alias(5)} to find out how aliases in \MH/ work;
+\item{\man mh-mail(5)} to find out how \MH/ stores and interprets messages
+(this manual entry explains all of the standard header components);
+\item{\man mh-profile(5)} to find out about the \MH/ user-environment.
+\smallskip}
+
+The manual pages for \MH/ are in the standard \unix/ format,
+but contain additional sections unique to \MH/.
+Here's a summary of the sections one might find in an \MH/ manual entry:
+\smallskip
+{\advance\leftskip by\parindent
+\item{\sc Name} command name and one-line description.
+
+\item{\sc Synopsis} syntax of the command.\hbreak
+All commands accept a \switch{help} switch.
+
+\item{\sc Description} semantics of the command.
+
+\item{\sc Files} files used by the command\hbreak
+Almost always this includes \file{.mh\_profile}.
+
+\item{\sc Profile} entries in the \profile/ used by the command;
+\vskip -\parskip
+\item{\sc Components} these do not include the profile entry for the
+command itself.
+
+\item{\sc See Also} other \unix/ manual entries (usually \MH/ programs) that
+are related to this command.
+
+\item{\sc Defaults} default arguments for the command\hbreak
+If the command takes a \arg{+folder} argument,
+this defaults to the current folder.
+If the command takes a \arg{msg} argument,
+this defaults to the current message.
+If the command takes a \arg{msgs} argument,
+this defaults to the current message or all messages,
+depending on which one makes more sense.
+
+\item{\sc Context} changes to your \MH/ context made by the command.
+
+\item{\sc Hints} Helpful hints discussing the easy way to do things.
+
+\item{\sc History} A historical perspective on why \MH/ works the way it does.
+
+\item{\sc Bugs} Too embarrassing to mention.\hbreak
+Just kidding.
+\medskip}
+\noindent
+Obviously, not all \MH/ manual entries may have all of these sections.
+
+\section{Reporting Problems}
+If problems are encountered with an \MH/ program,
+the problems should be reported to the local maintainers of \MH/.
+When doing this,
+the name of the program should be reported,
+along with the version information for the program.
+To find out what version of an \MH/ program is being run,
+invoke the program with the \switch{help} switch.
+In addition to listing the syntax of the command,
+the program will list information pertaining to its version.
+This information includes the version of \MH/,
+the host it was generated on,
+the date the program was loaded,
+and the configuration options in effect when \MH/ was generated.
+For example,
+\example
+    version: MH 6.1 \#1[UCI] (gremlin) of Wed Nov  6 01:13:53 PST 1985\\
+    options: [BSD42] [MHE] [NETWORK] [SENDMTS] [MMDFII] [SMTP] [POP]\endexample
+The \eg{6.1~\#1[UCI]} indicates that the program is from the UCI \mh6
+version of \MH/.
+The program was generated on the host \eg{gremlin} on
+\eg{Wed Nov  6 01:13:53 PST 1985}.
+It's usually a good idea to send the output of the \switch{help} switch along
+with your report.
+
+If there is no local \MH/ maintainer,
+try the address {\tx Bug-MH}.
+If that fails, use the Internet mailbox {\tx address@hidden
+
+\section{More on MH}
+There are myriad aspects of \MH/ that this tutorial hasn't touched upon.
+Here are a few to whet your appetite:
+\smallskip
+{\advance\leftskip by\parindent
+\item{1.} user-defined sequences\hbreak
+Define {\it meaningful} message names and shorten type-in considerably
+(see \man pick(1) for details).
+
+\item{2.} draft folders\hbreak
+Maintain a folder of drafts so that more than one draft can be edited at a
+time,
+and allow a draft to be edited over several \unix/ sessions independently of
+other drafts
+(see the {\bf Advanced Features} section of the \MH/ user's manual for
+details).
+
+\item{3.} draft pushing\hbreak
+Post a draft in the background
+and immediately free your terminal for other activities
+(see the {\bf Advanced Features} section of the \MH/ user's manual for
+details).
+
+\item{4.} aliases\hbreak
+Maintain one or more alias files containing the addresses of the people
+frequently (or infrequently) sent to.
+This lets you shorten type-in of addressees
+and saves you from looking up
+their addresses all the time.
+(see \man mh-alias(5) for details).

+\noindent
+This document introduces the UCI version of the Rand \MH/ system to novice
