+The mail transport method to use. The two acceptable options are \fBsmtp\fP
+(which is the default), and \fBsendmail\fP.
+
+If you use \fBsmtp\fP, this will enable a direct SMTP (simple mail transport
+protocol) interface in \fInmh\fR. When sending mail, instead of passing the
+message to the mail transport agent, \fIpost\fR will open a socket connection
+to the mail port on the machine specified in the \fIservers\fR entry.
+
+If you use \fBsendmail\fP, then \fIpost\fR will send messages by forking a
+local copy of sendmail. Currently it will still speak SMTP with this local
+copy of sendmail.
