-The first way is GECOS\-based username masquerading.  If the 
\*(lqmasquerade:\*(rq line
-.I mts.conf
-contains \*(lqmmailid\*(rq, this processing is activated.  If a user's GECOS
-field in the passwd file is of the form \*(lqFull Name <fakename>\*(rq then 
-will be used in place of the real username.  For instance, a GECOS field of 
-Harkless <Dan.Harkless>\*(rq would result in \*(lqFrom: Dan Harkless
-<address@hidden>\*(rq.  Naturally if you were doing something like
-this you'd want to set up an MTA alias (e.g. in /etc/aliases) from, for
-instance, \*(lqDan.Harkless\*(rq to \*(lqdan\*(rq.
-The second way to override default construction of \*(lqFrom:\*(rq is to set 
-environment variable.  This variable overrides the full name
-from the GECOS field, even if GECOS\-based masquerading is being done.  This
-processing is always active, and does not need to be enabled from
-.IR mts.conf .
-The third way is controlled by the \*(lquser_extension\*(rq value of 
\*(lqmasquerade:\*(rq line
-.IR mts.conf .
-When that's turned on, setting the
-environment variable will result in its value being appended the user's login
-name.  For instance, if I set
-to \*(lq+www\*(rq, my \*(lqFrom:\*(rq
-line will contain \*(lqDan Harkless <address@hidden>\*(rq (or
-\*(lqDan.Harkless+www\*(rq if I'm using mmailid masquerading as well).  Recent

-.B qmail

-default, but can use other characters as well.
+The first way is to supply a \*(lqSender:\*(rq line.  The value of this
+field will be used as the originating mailbox identity when submitting the
+message to the mail transport system.  If multiple addresses are
+given in the \*(lqFrom:\*(rq line, a \*(lqSender:\*(rq line is

+If an \*(lqEnvelope-From:\*(rq line is supplied when multiple addresses
+are given in the \*(lqFrom:\*(rq line, a \*(lqSender:\*(rq header will
+be generated using the value of the \*(lqEnvelope-From:\*(rq line,

-The fourth method of address masquerading is to specify a \*(lqFrom:\*(rq line 
-in the message draft.  It will be used as provided (after alias substitution),
-but normally, to discourage email forgery, the user's
-.B real
-address will be
-used in the SMTP envelope \*(lqFrom:\*(rq and in a \*(lqSender:\*(rq header.  
However, if the
-\*(lqmasquerade:\*(rq line of
-.I mts.conf
-contains \*(lqdraft_from\*(rq, the SMTP envelope \*(lqFrom:\*(rq
-will use the address given in the draft \*(lqFrom:\*(rq, and there will be no 
-header.  This is useful in pretending to send mail \*(lqdirectly\*(rq from a 
remote POP3
-account, or when remote email robots give improper precedence to the envelope
-\*(lqFrom:\*(rq.  Note that your MTA may still reveal your real identity (e.g.
-.BR sendmail 's

+The second way is to supply a \*(lqEnvelope-From:\*(rq line.  The value
+of this field will be used as the originating mailbox identity when
+submitting the message to the mail transport system.  This will override
+both the value of the \*(lqFrom:\*(rq line and a \*(lqSender:\*(rq line
+(if one is supplied).  The \*(lqEnvelope-From:\*(rq line is allowed to
+have a blank value; if the value is blank, then the mail transport system
+will be instructed to not send any bounces in response to the message.
