-.SH DESCRIPTION
-THIS IS OUT OF DATE AND NEEDS REWORKING.
-
-\fInmh\fR can use a wide range of message transport systems to deliver
-mail. Although the \fInmh\fR administrator usually doesn't get to choose
-which MTS to use (since it's already in place), this document briefly
-describes the interfaces.
-
-When communicating with \fISendMail\fR, \fInmh\fR always uses the SMTP to
-post mail. Depending on the \fInmh\fR configuration, \fISendMail\fR may
-be invoked directly (via a \fIfork\fR and an \fIexec\fR), or \fInmh\fR
-may open a TCP/IP connection to the SMTP server on the localhost.
-
-When communicating with \fIzmailer\fP, the \fISendMail\fP compatibility
-program is required to be installed in /usr/lib. \fInmh\fP communicates
-with \fIzmailer\fP by using the SMTP. It does this by invoking the
-\fB/usr/lib/sendmail\fP compatibility program directly, with the
-`\-bs' option.
-
-When communicating with \fIMMDF\fR, normally \fInmh\fR uses the
-\*(lqmm\(ru\*(rq routines to post mail. However, depending on the
-\fInmh\fR configuration, \fInmh\fR instead may open a TCP/IP connection
-to the SMTP server on the localhost.
-
-If you are running a UNIX system with TCP/IP networking, then it is
-felt that the best interface is achieved by using either \fISendMail\fR
-or \fIMMDF\fR with the SMTP option. This gives greater flexibility.
-To enable this option you append the /smtp suffix to the mts option
-in the \fInmh\fR configuration. This yields two primary advantages:
-First, you don't have to know where \fIsubmit\fR or \fISendMail\fR live.
-This means that \fInmh\fR binaries (e.g., \fIpost\fR\0) don't have to have
-this information hard\-coded, or can run different programs altogether;
-and, second, you can post mail with the server on different systems, so
-you don't need either \fIMMDF\fR or \fISendMail\fR on your local host.
-Big win in conserving cycles and disk space. Since \fInmh\fR supports
-the notion of a server search\-list in this respect, this approach can
-be tolerant of faults. Be sure to set \*(lqservers:\*(rq as described
-in mh\-tailor(8) if you use this option.
-
-There are four disadvantages to using the SMTP option: First, only UNIX
-systems with TCP/IP are supported. Second, you need to have an SMTP
-server running somewhere on any network your local host can reach.
-Third, this bypasses any authentication mechanisms in \fIMMDF\fR
-or \fISendMail\fR. Fourth, the file \fB/etc/hosts\fR is used for
-hostname lookups (although there is an exception file). In response
-to these disadvantages though: First, there's got to be an SMTP server
-somewhere around if you're in the Internet or have a local network.
-Since the server search\-list is very general, a wide\-range of options
-are possible. Second, SMTP should be fixed to have authentication
-mechanisms in it, like POP. Third, \fInmh\fR won't choke on mail to
-hosts whose official names it can't verify, it'll just plug along (and
-besides if you enable the DUMB configuration options, \fInmh\fR
-ignores the hosts file altogether).
