There shouldn't be any Listserv-specific tuning required on the Sendmail
relay box - about all you will need for a recent Sendmail is to tell it:

1) Your listserv machine is allowed to relay out to the world through it.
2) The world is allowed to relay to the Listerv box through it (only needed
if your Sendmail relay appears to the world as the primary MX for your
listserv box, and the NT box is *not* catching its inbound mail itself).

The biggest non-Listserv specific issue on your Sendmail relay will be
queue management - if you are expecting high loads of mail (over 100K
or so pieces a day), you certainly want to be running Sendmail 8.11.2
(recently released) and use the multiple-queue sypport with re-mqueue.pl
to "age" your queues.

Feel free to ask if there's other issues you'd like help with...
