I'm looking for a nice relay-proof sendmail.cf, and frankly, the stuff I'm
using was probably old in 1997.  :)  I'm wondering if anyone's got a nice
.mc for -current or 1.4_BETA, and/or pointers to a nice set of anti-relay
hacks, etc etc.

This'll just be running on one of our backup mail servers, but I'd like to
do the obvious stuff (RBL lookups, etc.) just for safe-keeping.
