-.BR masquerade:
-.RS 5
-This directive controls three different types of email address masquerading.
-The three possible values, which may be specified in any combination on the
-line, separated by spaces, are \*(lqdraft_from\*(rq, \*(lqmmailid\*(rq, and
-\*(lqusername_extension\*(rq.
-.PP
-\*(lqmmailid\*(rq was the only type of masquerading in the original MH package, and
-apparently stands for \*(lqmasquerade mail identification\*(rq. This type of
-masquerading keys off of the GECOS field of the passwd file. When enabled,
-.B nmh
-will check if the user's pw_gecos field in the passwd file is of the
-form:
-.PP
-.RS 5
-Full Name <fakeusername>
-.RE
-.PP
-If it is, the internal
-.B nmh
-routines that find the username and full name
-of that user will return \*(lqfakeusername\*(rq and \*(lqFull Name\*(rq respectively. This is
-useful if you want the messages you send to always appear to come from the name
-of an MTA alias rather than your actual account name. For instance, many
-organizations set up \*(lqFirst.Last\*(rq sendmail aliases for all users. If this is
-the case, the GECOS field for each user should look like:
-.PP
-.RS 5
-First [Middle] Last <First.Last>
-.RE
-.PP
-\*(lqusername_extension\*(rq, when specified on the \*(lqmasquerade:\*(rq line, allows a second
-type of username masquerading. If the user sets the
-.B $USERNAME_EXTENSION
-environment variable, its value will be appended to the actual login name. For
-instance, if I am \*(lqdan@company.com\*(rq, and I set
-.B $USERNAME_EXTENSION
-to \*(lq\-www\*(rq, my mail will appear to come from \*(lqdan\-www@company.com\*(rq. This is meant
-to interact with qmail's \*(lquser\-extension\*(rq feature, where mail sent to
-.IR user \- string
-will be delivered to
-.IR user .
-Likewise, those using
-versions of sendmail for which \*(lqplussed user\*(rq processing is active can set
-.B $USERNAME_EXTENSION
-to \*(lq+\fIstring\fR\*(rq. 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
-.B $USERNAME_EXTENSION
-is only appended to the username when \fIpost\fR is
-generating \*(lq[Resent\-]From:\*(rq lines and the SMTP envelope
-\*(lqFrom:\*(rq.
-.BR inc ,
-for instance, will not try to read from a maildrop file called \*(lqdan\-www\*(rq (to
-recall the earlier example).
-.PP
-\*(lqdraft_from\*(rq controls the most powerful type of address masquerading. Normally,
-when a user explicitly specifies a \*(lqFrom:\*(rq header in a draft,
-.B nmh
-uses it
-rather than constructing its own. However, to discourage email forgery, the
-SMTP envelope \*(lqFrom:\*(rq and a \*(lqSender:\*(rq header are set to the user's real address.
-When \*(lqdraft_from\*(rq is turned on, though, the envelope \*(lqFrom:\*(rq will use the
-address specified in the draft, and there will be no \*(lqSender:\*(rq header. This is
-useful when a user wants to pretend to be sending mail \*(lqdirectly\*(rq from a remote
-POP3 account, or when remote mail robots incorrectly use the envelope \*(lqFrom:\*(rq in
-preference to the body \*(lqFrom:\*(rq (or refuse to take action when the two don't
-match). Note that the MTA may still reveal the user's real identity (e.g.
-.BR sendmail 's
-\*(lqX\-Authentication\-Warning:\*(rq header).
