-mmailid: 0
-.br
-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).

-locking style and locking directory (if any).  The first controls the
-method of locking, the second says where lock files should be created.

-you want to use the \fIflock\fP system call; define \fBLOCKF_LOCKING\fP if
-you want to use the \fIlockf\fP system call; or define \fBFCNTL_LOCKING\fP
-if you want to use the \fIfcntl\fP system call for kernel-level locking.
-
-Instead of kernel locking, you can configure \fInmh\fR to use dot
-locking by defining \fBDOT_LOCKING\fP.  Dot locking specifies that
-a file should be created whose existence means \*(lqlocked\*(rq and
-whose non-existence means \*(lqunlocked\*(rq.  The name of this file is
-constructed by appending \*(lq.lock\*(rq to the name of the file being
-locked.  If \fBLOCKDIR\fP is not specified, lock files will be created
