-If this is non-zero, two different types of email address masquerading are
-allowed ("mmailid" = "masquerade mail ID"). The first type is GECOS-based
-masquerading. \fInmh\fR will check if the user's pw_gecos field in the passwd
-file is of the form:
-
-.ti +.5i
-Full Name <fakeusername>
-
-If it is, the internal \fInmh\fR routines that find the username and full name
-of that user will return "fakeusername" and "Full Name" 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 "First.Last" sendmail aliases for all users. If this is
-the case, the GECOS field for each user should look like:
-
-.ti +.5i
-First [Middle] Last <First.Last>
-
-The other type of masquerading that mmailid turns on is envelope "From:"
-masquerading based on draft contents. When a user explicitly specifies a
-"From:" header in a message, \fInmh\fR uses it rather than constructing its own.
-However, the SMTP envelope "From:" and the "Sender:" header are set to the
-user's real address. Turning on mmailid prevents this latter behavior. This is
-useful when the 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).
