+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.

This directive controls three different types of email address masquerading.
The three possible values, which may be specified in any combination on the

"mmailid" was the only type of masquerading in the original MH package, and
apparently stands for "masquerade mail identification". This type of

-"plussed_user", when specified on the "masquerade:" line, allows a second type
-of username masquerading. If the user sets the \fB$USERPLUS\fR environment
-variable, its value will be tacked onto the actual login name, following a '+'
-sign. For instance, if I am dan@company.com, and I set \fB$USERPLUS\fR to
-"www", my mail will appear to come from "dan+www@company.com". This feature is
-meant to interact with MTA features like the one in sendmail that automatically
-delivers all mail sent to \fIuser\fR+\fIstring\fR to \fIuser\fR. One can use
-different email addresses in different situations (to aid in automatic mail
-filtering or in determining where spammers got your address) while only actually
-having a single account.
+"username_extension", when specified on the "masquerade:" line, allows a second
+type of username masquerading. If the user sets the \fB$USERNAME_EXTENSION\fR
+environment variable, its value will be appended to the actual login name. For
+instance, if I am dan@company.com, and I set \fB$USERNAME_EXTENSION\fR to
+"\-www", my mail will appear to come from "dan\-www@company.com". This is meant
+to interact with qmail's "user\-extension" feature, where mail sent to
+\fIuser\fR\-\fIstring\fR will be delivered to \fIuser\fR. Likewise, those using
+versions of sendmail for which "plussed user" processing is active can set
+\fB$USERNAME_EXTENSION\fR to "+\fIstring\fR". These MTA features are useful
+because they allow one to use different email addresses in different situations
+(to aid in automatic mail filtering or in determining where spammers got one's
+address) while only actually having a single account. Note that
+\fB$USERNAME_EXTENSION\fR is only appended to the username when \fIpost\fR is
+generating "[Resent\-]From:" lines and the SMTP envelope "From:". \fIinc\fR,
+for instance, will not try to read from a maildrop file called "dan\-www" (to
+recall the earlier example).
"draft_from" controls the most powerful type of address masquerading. Normally,
when a user explicitly specifies a "From:" header in a draft, \fInmh\fR uses it
useful when a user wants to pretend to be sending mail "directly" from a remote
POP3 account, or when remote mail robots incorrectly use the envelope "From:" in
preference to the body "From:" (or refuse to take action when the two don't
-match). Note that your MTA may still reveal the user's real identity (e.g.
-sendmail's "X-Authentication-Warning:" header).
