All sendmail needs is just plain old TCP/IP.  So if you're doing network
printing, or VT-MGR terminal sessions, you've already got TCP/IP configured
properly.

So your LAN is not connected full-time to the Internet, and the only connection
to the outside world is when the NT machine dials your ISP to exchange e-mail
periodically?

Yes, sendmail is capable of doing this.  You'll need to configure sendmail to
use the NT machine as a "smart host" (IIRC).  Sendmail will then just relay all
outbound e-mail to the one configured smart host, and it's up to the smart host
to worry about final delivery or further relaying.

I've personally never configured a smart host because my sendmails always have
full Internet access, but I do know this is a fairly common configuration
choice for Sendmail/iX users.
