This is your problem exactly.  If you really want to run sendmail, you
have to uninstall mmdf, because they both attempt to listen for SMTP
connections (actually the inetd and sendmail both attempt to listen).

In reverse order:  You cannot configure the version of mmdf that you are
running to talk to the nameserver.  This has been corrected in the next
release of SCO MMDF.  The way to get mmdf to communicate with remote
sendmail daemons is to properly configure MMDF to do so.  Since you have
been spending all your time trying to fix you perceived sendmail
problems, you probably haven't worked very hard on MMDF (that's not a
flame, I would have done the same thing).

MMDF is only better that sendmail in one (very important) way:  normal
human beings can understand how to configure it in about 15 minutes, and
can read the configuration files without having the manual beside them.
Aside from that, MMDF and Sendmail solve basically the same problem in
basically the same way.

You're talking to one (but we didn't relay things through sendmail to the
Internet, just the rest of UUCPnet, but the idea is the same for the MMDF
nodes).

This is very trivial to do with MMDF as well.  Phone SCO support and ask
for the fax-pack which describes configuring SCO MMDF in a TCP/IP
environment (it's also been posted to this newsgroup at least once).
