address@hidden message
+
+  To send a message in Emacs, you start by typing a command (@kbd{C-x m})
+to select and initialize the @samp{*mail*} buffer.  Then you edit the text
+and headers of the message in this buffer, and type another command
+(@kbd{C-c C-s} or @kbd{C-c C-c}) to send the message.
+
address@hidden @kbd

+Send the message and bury the mail buffer (@code{mail-send-and-exit}).

address@hidden C-x m
address@hidden compose-mail
address@hidden C-x 4 m
address@hidden compose-mail-other-window
address@hidden C-x 5 m
address@hidden compose-mail-other-frame
+  The command @kbd{C-x m} (@code{compose-mail}) selects a buffer named
address@hidden and initializes it with the skeleton of an outgoing
+message.  @kbd{C-x 4 m} (@code{compose-mail-other-window}) selects the
address@hidden buffer in a different window, leaving the previous current
+buffer visible.  @kbd{C-x 5 m} (@code{compose-mail-other-frame}) creates
+a new frame to select the @samp{*mail*} buffer.
+
+  Because the mail-composition buffer is an ordinary Emacs buffer, you can
+switch to other buffers while in the middle of composing mail, and switch
+back later (or never).  If you use the @kbd{C-x m} command again when you
+have been composing another message but have not sent it, you are asked to
+confirm before the old message is erased.  If you answer @kbd{n}, the
address@hidden buffer remains selected with its old contents, so you can
+finish the old message and send it.  @kbd{C-u C-x m} is another way to do
+this.  Sending the message marks the @samp{*mail*} buffer ``unmodified,''
+which avoids the need for confirmation when @kbd{C-x m} is next used.
+
+  If you are composing a message in the @samp{*mail*} buffer and want to
+send another message before finishing the first, rename the
address@hidden buffer using @kbd{M-x rename-uniquely} (@pxref{Misc
+Buffer}).  Then you can use @kbd{C-x m} or its variants described above
+to make a new @samp{*mail*} buffer.  Once you've done that, you can work
+with each mail buffer independently.

+directory for mail buffers, and also says where to put their auto-save

address@hidden Mail Format
address@hidden The Format of the Mail Buffer
+
+  In addition to the @dfn{text} or @dfn{body}, a message has @dfn{header
+fields} which say who sent it, when, to whom, why, and so on.  Some
+header fields, such as @samp{Date} and @samp{Sender}, are created
+automatically when you send the message.  Others, such as the recipient
+names, must be specified by you in order to send the message properly.
+
+  In the mail buffer, you can insert and edit header fields using
+ordinary editing commands.  Mail mode provides a commands to help you
+edit some header fields, and some are preinitialized in the buffer
+automatically when appropriate.
+
+  The line in the buffer that says
+
address@hidden
+--text follows this line--
address@hidden example
+
address@hidden
+is a special delimiter that separates the headers you have specified from
+the text.  Whatever follows this line is the text of the message; the
+headers precede it.  The delimiter line itself does not appear in the
+message actually sent.  The text used for the delimiter line is controlled
+by the variable @code{mail-header-separator}.
+
+  Here is an example of what the headers and text in the mail buffer
+might look like.

address@hidden Mail Headers
address@hidden Mail Header Fields
address@hidden headers (of mail message)
+
+  A header field in the mail buffer starts with a field name at the
+beginning of a line, terminated by a colon.  Upper and lower case are
+equivalent in field names (and in mailing addresses also).  After the
+colon and optional whitespace comes the contents of the field.
+
+  You can use any name you like for a header field, but normally people
+use only standard field names with accepted meanings.  Here is a table
+of fields commonly used in outgoing messages.
+
address@hidden @samp
address@hidden To
+This field contains the mailing addresses to which the message is
+addressed.  If you list more than one address, use commas, not spaces,
+to separate them.
+
address@hidden Subject
+The contents of the @samp{Subject} field should be a piece of text
+that says what the message is about.  The reason @samp{Subject} fields
+are useful is that most mail-reading programs can provide a summary of
+messages, listing the subject of each message but not its text.
+
address@hidden CC
+This field contains additional mailing addresses to send the message to,
+like @samp{To} except that these readers should not regard the message
+as directed at them.
+
address@hidden BCC
+This field contains additional mailing addresses to send the message to,
+which should not appear in the header of the message actually sent.
+Copies sent this way are called @dfn{blind carbon copies}.
+
address@hidden mail-self-blind
address@hidden copy of every outgoing message
+To send a blind carbon copy of every outgoing message to yourself, set
+the variable @code{mail-self-blind} to @code{t}.  To send a blind carbon
+copy of every message to some other @var{address}, set the variable
address@hidden to @code{"Bcc: @var{address}\n"}.
+
address@hidden FCC
+This field contains the name of one file and directs Emacs to append a
+copy of the message to that file when you send the message.  If the file
+is in Rmail format, Emacs writes the message in Rmail format; otherwise,
+Emacs writes the message in system mail file format.  To specify
+more than one file, use several @samp{FCC} fields, with one file
+name in each field.
+
address@hidden mail-archive-file-name
+To put a fixed file name in the @samp{FCC} field each time you start
+editing an outgoing message, set the variable
address@hidden to that file name.  Unless you remove the
address@hidden field before sending, the message will be written into that
+file when it is sent.
+
address@hidden From
+Use the @samp{From} field to say who you are, when the account you are
+using to send the mail is not your own.  The contents of the @samp{From}
+field should be a valid mailing address, since replies will normally go
+there.  If you don't specify the @samp{From} field yourself, Emacs uses
+the value of @code{user-mail-address} as the default.
+
address@hidden Reply-to
+Use this field to direct replies to a different address.  Most
+mail-reading programs (including Rmail) automatically send replies to
+the @samp{Reply-to} address in preference to the @samp{From} address.
+By adding a @samp{Reply-to} field to your header, you can work around
+any problems your @samp{From} address may cause for replies.
+
address@hidden @env{REPLYTO} environment variable
address@hidden mail-default-reply-to
+To put a fixed @samp{Reply-to} address into every outgoing message, set
+the variable @code{mail-default-reply-to} to that address (as a string).
+Then @code{mail} initializes the message with a @samp{Reply-to} field as
+specified.  You can delete or alter that header field before you send
+the message, if you wish.  When Emacs starts up, if the environment
+variable @env{REPLYTO} is set, @code{mail-default-reply-to} is
+initialized from that environment variable.
+
address@hidden In-reply-to
+This field contains a piece of text describing the message you are
+replying to.  Some mail systems can use this information to correlate
+related pieces of mail.  Normally this field is filled in by Rmail
+when you reply to a message in Rmail, and you never need to
+think about it (@pxref{Rmail}).
+
address@hidden References
+This field lists the message IDs of related previous messages.  Rmail
+sets up this field automatically when you reply to a message.
address@hidden table
+
+  The @samp{To}, @samp{CC}, and @samp{BCC} header fields can appear
+any number of times, and each such header field can contain multiple
+addresses, separated by commas.  This way, you can specify any number
+of places to send the message.  These fields can also have
+continuation lines: one or more lines starting with whitespace,
+following the starting line of the field, are considered part of the
+field.  Here's an example of a @samp{To} field with a continuation
+line:
+
address@hidden
address@hidden
+To: foo@@here.net, this@@there.net,
+  me@@gnu.cambridge.mass.usa.earth.spiral3281
address@hidden group
address@hidden example
+
address@hidden mail-from-style
+  When you send the message, if you didn't write a @samp{From} field
+yourself, Emacs puts in one for you.  The variable
address@hidden controls the format:
+
address@hidden @code
address@hidden nil
+Use just the email address, as in @samp{king@@grassland.com}.
address@hidden parens
+Use both email address and full name, as in:@*
address@hidden@@grassland.com (Elvis Parsley)}.
address@hidden angles
+Use both email address and full name, as in:@*
address@hidden Parsley <king@@grassland.com>}.
address@hidden system-default
+Allow the system to insert the @samp{From} field.
address@hidden table
+
address@hidden mail-default-headers
+  You can direct Emacs to insert certain default headers into the
+outgoing message by setting the variable @code{mail-default-headers}
+to a string.  Then @code{C-x m} inserts this string into the message
+headers.  If the default header fields are not appropriate for a
+particular message, edit them as appropriate before sending the
+message.
+
address@hidden Mail Aliases
address@hidden Mail Aliases
address@hidden mail aliases
address@hidden @file{.mailrc} file
address@hidden mailrc file
+
+  You can define @dfn{mail aliases} in a file named @file{~/.mailrc}.
+These are short mnemonic names which stand for mail addresses or groups of
+mail addresses.  Like many other mail programs, Emacs expands aliases
+when they occur in the @samp{To}, @samp{From}, @samp{CC}, @samp{BCC}, and
address@hidden fields, plus their @samp{Resent-} variants.
+
+  To define an alias in @file{~/.mailrc}, write a line in the following
+format:
+
address@hidden
+alias @var{shortaddress} @var{fulladdresses}
address@hidden example
+
address@hidden
+Here @var{fulladdresses} stands for one or more mail addresses for
address@hidden to expand into.  Separate multiple addresses with
+spaces; if an address contains a space, quote the whole address with a
+pair of double-quotes.
+
+For instance, to make @code{maingnu} stand for
address@hidden@@gnu.org} plus a local address of your own, put in
+this line:@refill
+
address@hidden
+alias maingnu gnu@@gnu.org local-gnu
address@hidden example
+
address@hidden
+Addresses specified in this way should use doublequotes around an
+entire address when the address contains spaces.  But you need not
+include doublequotes around parts of the address, such as the person's
+full name.  Emacs puts them in if they are needed.  For example,
+
address@hidden
+alias chief-torturer "George W. Bush <bush@@whitehouse.gov>"
address@hidden example
+
address@hidden
+is correct in @samp{.mailrc}.  Emacs will insert the address as
address@hidden"George W. Bush" <bush@@whitehouse.gov>}.
+
+  Emacs also recognizes ``include'' commands in @samp{.mailrc} files.
+They look like this:
+
address@hidden
+source @var{filename}
address@hidden example
+
address@hidden
+The file @file{~/.mailrc} is used primarily by other mail-reading
+programs; it can contain various other commands.  Emacs ignores
+everything in it except for alias definitions and include commands.
+
address@hidden define-mail-alias
+  Another way to define a mail alias, within Emacs alone, is with the
address@hidden command.  It prompts for the alias and then the
+full address.  You can use it to define aliases in your @file{.emacs}
+file, like this:
+
address@hidden
+(define-mail-alias "maingnu" "gnu@@gnu.org")
address@hidden example
+
address@hidden mail-aliases
+  @code{define-mail-alias} records aliases by adding them to a
+variable named @code{mail-aliases}.  If you are comfortable with
+manipulating Lisp lists, you can set @code{mail-aliases} directly.  The
+initial value of @code{mail-aliases} is @code{t}, which means that
+Emacs should read @file{.mailrc} to get the proper value.
+
address@hidden mail-personal-alias-file
+  You can specify a different file name to use instead of
address@hidden/.mailrc} by setting the variable
address@hidden
+
address@hidden expand-mail-aliases
+  Normally, Emacs expands aliases when you send the message.  You do not
+need to expand mail aliases before sending the message, but you can
+expand them if you want to see where the mail will actually go.  To do
+this, use the command @kbd{M-x expand-mail-aliases}; it expands all mail
+aliases currently present in the mail headers that hold addresses.
+
+  If you like, you can have mail aliases expand as abbrevs, as soon as
+you type them in (@pxref{Abbrevs}).  To enable this feature, execute the
+following:
+
address@hidden
+(add-hook 'mail-mode-hook 'mail-abbrevs-setup)
address@hidden example
+
address@hidden
address@hidden define-mail-abbrev
address@hidden mail-abbrevs
+This can go in your @file{.emacs} file.  @xref{Hooks}.  If you use this
+feature, you must use @code{define-mail-abbrev} instead of
address@hidden; the latter does not work with this package.
+Note that the mail abbreviation package uses the variable
address@hidden instead of @code{mail-aliases}, and that all alias
+names are converted to lower case.
+
address@hidden C-c C-a @r{(Mail mode)}
address@hidden mail-interactive-insert-alias
+  The mail abbreviation package also provides the @kbd{C-c C-a}
+(@code{mail-interactive-insert-alias}) command, which reads an alias
+name (with completion) and inserts its definition at point.  This is
+useful when editing the message text itself or a header field such as
address@hidden in which Emacs does not normally expand aliases.
+
+  Note that abbrevs expand only if you insert a word-separator character
+afterward.  However, you can rebind @kbd{C-n} and @kbd{M->} to cause
+expansion as well.  Here's how to do that:
+
address@hidden
+(add-hook 'mail-mode-hook
+    (lambda ()
+      (define-key
+        mail-mode-map [remap next-line] 'mail-abbrev-next-line)
+      (define-key
+        mail-mode-map [remap end-of-buffer] 'mail-abbrev-end-of-buffer)))
address@hidden smallexample
+
address@hidden Mail Mode
address@hidden Mail Mode
address@hidden Mail mode
address@hidden mode, Mail
+
+  The major mode used in the mail buffer is Mail mode, which is much
+like Text mode except that various special commands are provided on the
address@hidden prefix.  These commands all have to do specifically with
+editing or sending the message.  In addition, Mail mode defines the
+character @samp{%} as a word separator; this is helpful for using the
+word commands to edit mail addresses.
+
+  Mail mode is normally used in buffers set up automatically by the
address@hidden command and related commands.  However, you can also switch
+to Mail mode in a file-visiting buffer.  This is a useful thing to do if
+you have saved the text of a draft message in a file.
+

address@hidden Mail Sending
address@hidden Mail Sending
+
+  Mail mode has two commands for sending the message you have been
+editing:
+
address@hidden @kbd
address@hidden C-c C-s
+Send the message, and leave the mail buffer selected (@code{mail-send}).
address@hidden C-c C-c
+Send the message, and select some other buffer (@code{mail-send-and-exit}).
address@hidden table
+
address@hidden C-c C-s @r{(Mail mode)}
address@hidden C-c C-c @r{(Mail mode)}
address@hidden mail-send
address@hidden mail-send-and-exit
+  @kbd{C-c C-s} (@code{mail-send}) sends the message and marks the mail
+buffer unmodified, but leaves that buffer selected so that you can
+modify the message (perhaps with new recipients) and send it again.
address@hidden C-c} (@code{mail-send-and-exit}) sends and then deletes the
+window or switches to another buffer.  It puts the mail buffer at the
+lowest priority for reselection by default, since you are finished with
+using it.  This is the usual way to send the message.
+
+  In a file-visiting buffer, sending the message does not clear the
+modified flag, because only saving the file should do that.  Also, you
+don't get a warning if you try to send the same message twice.
+
address@hidden This is indexed in mule.texi, node "Recognize Coding".
address@hidden @vindex sendmail-coding-system
+  When you send a message that contains address@hidden characters, they need
+to be encoded with a coding system (@pxref{Coding Systems}).  Usually
+the coding system is specified automatically by your chosen language
+environment (@pxref{Language Environments}).  You can explicitly specify
+the coding system for outgoing mail by setting the variable
address@hidden (@pxref{Recognize Coding}).
+
+  If the coding system thus determined does not handle the characters in
+a particular message, Emacs asks you to select the coding system to use,
+showing a list of possible coding systems.
+
address@hidden SMTP
address@hidden Feedmail
address@hidden Sendmail
address@hidden send-mail-function
+  The variable @code{send-mail-function} controls how the default mail
+user agent sends mail.  It should be set to a function.  The default
+is @code{sendmail-send-it}, which delivers mail using the Sendmail
+installation on the local host.  To send mail through a SMTP server,
+set it to @code{smtpmail-send-it} and set up the Emacs SMTP library
+(@pxref{Top,,Emacs SMTP Library, smtpmail, Sending mail via SMTP}).  A
+third option is @code{feedmail-send-it}, see the commentary section of
+the @file{feedmail.el} package for more information.
+
address@hidden Header Editing
address@hidden Mail Header Editing
+
+  Mail mode provides special commands to move to particular header
+fields and to complete addresses in headers.
+
address@hidden @kbd
address@hidden C-c C-f C-t
+Move to the @samp{To} header field, creating one if there is none
+(@code{mail-to}).
address@hidden C-c C-f C-s
+Move to the @samp{Subject} header field, creating one if there is
+none (@code{mail-subject}).
address@hidden C-c C-f C-c
+Move to the @samp{CC} header field, creating one if there is none

address@hidden C-c C-f C-b
+Move to the @samp{BCC} header field, creating one if there is none
+(@code{mail-bcc}).
address@hidden C-c C-f C-f
+Move to the @samp{FCC} header field, creating one if there is none

address@hidden mail-bcc
address@hidden C-c C-f C-f @r{(Mail mode)}
address@hidden mail-fcc
+  There are five commands to move point to particular header fields, all
+based on the prefix @kbd{C-c C-f} (@samp{C-f} is for ``field'').  They
+are listed in the table above.  If the field in question does not exist,
+these commands create one.  We provide special motion commands for these
+particular fields because they are the fields users most often want to
+edit.
+
address@hidden mail-complete
address@hidden M-TAB @r{(Mail mode)}
+  While editing a header field that contains mailing addresses, such
+as @samp{To:}, @samp{CC:} and @samp{BCC:}, you can complete a mailing
+address by typing @address@hidden (@code{mail-complete}).  It
+inserts the full name corresponding to the address, if it can
+determine the full name.  The variable @code{mail-complete-style}
+controls whether to insert the full name, and what style to use, as in
address@hidden (@pxref{Mail Headers}).  (If your window
+manager defines @address@hidden to switch windows, you can type
address@hidden@key{ESC} @key{TAB}} or @kbd{C-M-i}.)
+
+  For completion purposes, the valid mailing addresses are taken to be
+the local users' names plus your personal mail aliases.  You can
+specify additional sources of valid addresses; see the customization
+group @samp{mailalias} to see the variables for customizing this
+feature (@pxref{Customization Groups}).
+
+  If you type @address@hidden in the body of the message,
address@hidden invokes @code{ispell-complete-word}, as in Text
+mode.
+
address@hidden Citing Mail
address@hidden Citing Mail
address@hidden citing mail
+
+  Mail mode also has commands for yanking or @dfn{citing} all or part of
+a message that you are replying to.  These commands are active only when
+you started sending a message using an Rmail command.
+
address@hidden @kbd
address@hidden C-c C-y
+Yank the selected message from Rmail (@code{mail-yank-original}).
address@hidden C-c C-r
+Yank the region from the Rmail buffer (@code{mail-yank-region}).
address@hidden C-c C-q
+Fill each paragraph cited from another message
+(@code{mail-fill-yanked-message}).
address@hidden table
+
address@hidden C-c C-y @r{(Mail mode)}
address@hidden mail-yank-original
+  When mail sending is invoked from the Rmail mail reader using an Rmail
+command, @kbd{C-c C-y} can be used inside the mail buffer to insert
+the text of the message you are replying to.  Normally it indents each line
+of that message three spaces and eliminates most header fields.  A numeric
+argument specifies the number of spaces to indent.  An argument of just
address@hidden says not to indent at all and not to eliminate anything.
address@hidden C-y} always uses the current message from the Rmail buffer,
+so you can insert several old messages by selecting one in Rmail,
+switching to @samp{*mail*} and yanking it, then switching back to
+Rmail to select another.
+
address@hidden mail-yank-prefix
+  You can specify the text for @kbd{C-c C-y} to insert at the beginning
+of each line: set @code{mail-yank-prefix} to the desired string.  (A
+value of @code{nil} means to use indentation; this is the default.)
+However, @kbd{C-u C-c C-y} never adds anything at the beginning of the
+inserted lines, regardless of the value of @code{mail-yank-prefix}.
+
address@hidden C-c C-r @r{(Mail mode)}
address@hidden mail-yank-region
+  To yank just a part of an incoming message, set the region in Rmail to
+the part you want; then go to the @samp{*Mail*} message and type
address@hidden C-r} (@code{mail-yank-region}).  Each line that is copied is
+indented or prefixed according to @code{mail-yank-prefix}.
+
address@hidden C-c C-q @r{(Mail mode)}
address@hidden mail-fill-yanked-message
+  After using @kbd{C-c C-y} or @kbd{C-c C-r}, you can type @kbd{C-c C-q}
+(@code{mail-fill-yanked-message}) to fill the paragraphs of the yanked
+old message or messages.  One use of @kbd{C-c C-q} fills all such
+paragraphs, each one individually.  To fill a single paragraph of the
+quoted message, use @kbd{M-q}.  If filling does not automatically
+handle the type of citation prefix you use, try setting the fill prefix
+explicitly.  @xref{Filling}.

address@hidden C-c C-t @r{(Mail mode)}
address@hidden mail-text
+  @kbd{C-c C-t} (@code{mail-text}) moves point to just after the header
+separator line---that is, to the beginning of the message body text.
+
address@hidden C-c C-w @r{(Mail mode)}
address@hidden mail-signature
address@hidden mail-signature
+  @kbd{C-c C-w} (@code{mail-signature}) adds a standard piece of text at
+the end of the message to say more about who you are.  The text comes
+from the file @file{~/.signature} in your home directory.  To insert
+your signature automatically, set the variable @code{mail-signature} to
address@hidden; after that, starting a mail message automatically inserts the
+contents of your @file{~/.signature} file.  If you want to omit your
+signature from a particular message, delete it from the buffer before
+you send the message.
+
+  You can also set @code{mail-signature} to a string; then that string
+is inserted automatically as your signature when you start editing a
+message to send.  If you set it to some other Lisp expression, the
+expression is evaluated each time, and its value (which should be a
+string) specifies the signature.
+
address@hidden ispell-message
+  You can do spelling correction on the message text you have written
+with the command @kbd{M-x ispell-message}.  If you have yanked an
+incoming message into the outgoing draft, this command skips what was
+yanked, but it checks the text that you yourself inserted.  (It looks
+for indentation or @code{mail-yank-prefix} to distinguish the cited
+lines from your input.)  @xref{Spelling}.
+
address@hidden C-c C-i @r{(Mail mode)}
address@hidden mail-attach-file
+  To include a file in the outgoing message, you can use @kbd{C-x i},
+the usual command to insert a file in the current buffer.  But it is
+often more convenient to use a special command, @kbd{C-c C-i}
+(@code{mail-attach-file}).  This command inserts the file contents at
+the end of the buffer, after your signature if any, with a delimiter
+line that includes the file name.  Note that this is not a MIME
+attachment.
+
address@hidden mail-mode-hook
address@hidden mail-setup-hook
+  Turning on Mail mode (which @kbd{C-x m} does automatically) runs the
+normal hooks @code{text-mode-hook} and @code{mail-mode-hook}.
+Initializing a new outgoing message runs the normal hook
address@hidden; if you want to add special fields to your mail
+header or make other changes to the appearance of the mail buffer, use
+that hook.  @xref{Hooks}.
+
+  The main difference between these hooks is just when they are
+invoked.  Whenever you type @kbd{M-x mail}, @code{mail-mode-hook} runs
+as soon as the @samp{*mail*} buffer is created.  Then the
address@hidden function inserts the default contents of the buffer.
+After these default contents are inserted, @code{mail-setup-hook} runs.

address@hidden spook
address@hidden NSA
+  @kbd{M-x spook} adds a line of randomly chosen keywords to an outgoing
+mail message.  The keywords are chosen from a list of words that suggest
+you are discussing something subversive.
+
+  The idea behind this feature is the suspicion that the
address@hidden US National Security Agency.} snoops on
+all electronic mail messages that contain keywords suggesting they might
+find them interesting.  (The NSA says they don't, but that's what they
address@hidden say.)  The idea is that if lots of people add suspicious
+words to their messages, the NSA will get so busy with spurious input
+that they will have to give up reading it all.
+
+  Here's how to insert spook keywords automatically whenever you start
+entering an outgoing message:
+
address@hidden
+(add-hook 'mail-setup-hook 'spook)
address@hidden example
+
+  Whether or not this confuses the NSA, it at least amuses people.
+
address@hidden fortune-to-signature
address@hidden fortune cookies
+  You can use the @code{fortune} program to put a ``fortune cookie''
+message into outgoing mail.  To do this, add
address@hidden to @code{mail-setup-hook}:
+
address@hidden
+(add-hook 'mail-setup-hook 'fortune-to-signature)

address@hidden MH mail interface
address@hidden Message mode for sending mail
+  In this chapter we have described the usual Emacs mode for editing
+and sending mail---Mail mode.  Emacs has alternative facilities for
+editing and sending mail, including
+MH-E and Message mode, not documented in this manual.
address@hidden,,MH-E,mh-e, The Emacs Interface to MH}.  
@xref{Top,,Message,message,
+Message Manual}.  You can choose any of them as your preferred method.
+The commands @code{C-x m}, @code{C-x 4 m} and @code{C-x 5 m} use
+whichever agent you have specified, as do various other Emacs commands
+and facilities that send mail.
+
address@hidden mail-user-agent
+  To specify your mail-composition method, customize the variable
address@hidden  Currently legitimate values include
address@hidden (Mail mode), @code{mh-e-user-agent},
address@hidden and @code{gnus-user-agent}.
+
+  If you select a different mail-composition method, the information
+in this chapter about the @samp{*mail*} buffer and Mail mode does not
+apply; the other methods use a different format of text in a different
+buffer, and their commands are different as well.
