.SH DESCRIPTION
-\fIPost\fR is the default program called by \fIsend\fR\0(1) to deliver
-the message in \fIfile\fR to local and remote users. In fact, most of
-the features attributed to \fIsend\fR in its manual page are performed by
-\fIpost\fR, with \fIsend\fR acting as a relatively simple preprocessor.
-Thus, it is \fIpost\fR which parses the various header fields, appends
-From: and Date: lines, and interacts with the mail transport system.
-\fIPost\fR will not normally be called directly by the user.

message will be a copy of the message sent to the sighted recipients.

+The

+.PP
+Under normal circumstances,
+.B post
+constructs the \*(lqFrom:\*(rq line of the
message from the user's login name, the full name from the GECOS field of the
-passwd file, and the fully\-qualified name of the local machine (or the value of
-"localname" in mts.conf, if set). An example is "From: Dan Harkless
-<dan@machine.company.com>". There are four ways to override these values,
-however. Note that they apply equally to "Resent\-From:" lines in messages sent
-with \fIdist\fR.
-
-The first way is GECOS\-based username masquerading. If the "masquerade:" line
-in mts.conf contains "mmailid", this processing is activated. If a user's GECOS
-field in the passwd file is of the form "Full Name <fakename>" then "fakename"
-will be used in place of the real username. For instance, a GECOS field of "Dan
-Harkless <Dan.Harkless>" would result in "From: Dan Harkless
-<Dan.Harkless@machine.company.com>". Naturally if you were doing something like
+passwd file, and the fully\-qualified name of the local machine (or the
+value of
+\*(lqlocalname\*(rq in
+.IR mts.conf ,
+if set). An example is \*(lqFrom: Dan Harkless
+<dan@machine.company.com>\*(rq. There are four ways to override these values,
+however. Note that they apply equally to \*(lqResent\-From:\*(rq lines in messages sent
+with
+.BR dist .
+.PP
+The first way is GECOS\-based username masquerading. If the \*(lqmasquerade:\*(rq line
+in
+.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 \*(lqfakename\*(rq
+will be used in place of the real username. For instance, a GECOS field of \*(lqDan
+Harkless <Dan.Harkless>\*(rq would result in \*(lqFrom: Dan Harkless
+<Dan.Harkless@machine.company.com>\*(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, "Dan.Harkless" to "dan".
-
-The second way to override default construction of "From:" is to set the
-\fB$SIGNATURE\fR environment variable. This variable overrides the full name
+instance, \*(lqDan.Harkless\*(rq to \*(lqdan\*(rq.
+.PP
+The second way to override default construction of \*(lqFrom:\*(rq is to set the
+.B $SIGNATURE
+environment variable. This variable overrides the full name
from the GECOS field, even if GECOS\-based masquerading is being done. This
-processing is always active, and does not need to be enabled from mts.conf.
-
-The third way is controlled by the "user_extension" value of "masquerade:" line
-of mts.conf. When that's turned on, setting the \fB$USERNAME_EXTENSION\fR
+processing is always active, and does not need to be enabled from
+.IR mts.conf .
+.PP
+The third way is controlled by the \*(lquser_extension\*(rq value of \*(lqmasquerade:\*(rq line
+of
+.IR mts.conf .
+When that's turned on, setting the
+.B $USERNAME_EXTENSION
environment variable will result in its value being appended the user's login
-name. For instance, if I set \fB$USERNAME_EXTENSION\fR to "+www", my "From:"
-line will contain "Dan Harkless <dan+www@machine.company.com>" (or
-"Dan.Harkless+www" if I'm using mmailid masquerading as well). Recent versions
-of sendmail automatically deliver all mail sent to \fIuser\fR+\fIstring\fR to
-\fIuser\fR. qmail has a similar feature which uses '\-' as the delimiter by
+name. For instance, if I set
+.B $USERNAME_EXTENSION
+to \*(lq+www\*(rq, my \*(lqFrom:\*(rq
+line will contain \*(lqDan Harkless <dan+www@machine.company.com>\*(rq (or
+\*(lqDan.Harkless+www\*(rq if I'm using mmailid masquerading as well). Recent versions
+of
+.B sendmail
+automatically deliver all mail sent to
+.IR user + string
+to
+.IR user .
+.B qmail
+has a similar feature which uses '\-' as the delimiter by
default, but can use other characters as well.

+The fourth method of address masquerading is to specify a \*(lqFrom:\*(rq line manually
in the message draft. It will be used as provided (after alias substitution),
-but normally, to discourage email forgery, the user's \fIreal\fR address will be
-used in the SMTP envelope "From:" and in a "Sender:" header. However, if the

+contains \*(lqdraft_from\*(rq, the SMTP envelope \*(lqFrom:\*(rq

+.PP
+If
+.B nmh
+has been compiled with SASL support, the
+.B \-sasl
+switch will enable
+the use of SASL authentication with the SMTP MTA. Depending on the
+SASL mechanism used, this may require an additional password prompt from the
+user (but the
+.RI \*(lq \&.netrc \*(rq
+file can be used to store this password).
+.B \-saslmech

+and the the
+.B \-user
+switch can be used to select a authorization userid
+to provide to SASL other than the default.
+.PP
+Currently SASL security layers are not supported for SMTP.
+.BR nmh 's
+SMTP SASL code
+will always negotiate an unencrypted connection. This means that while the SMTP

+contrast to

+POP3 SASL support, where encryption is supported for both the
+authentication and the data stream.
