Recpmmended Sendmail resources?

[Andrew Pollock <andrew@andrew.net.au>]

Is it just me, or does sendmail.org really suck? Especially in terms of up to
date information?

I can think of a few questions that I can never seem to easily find the answer
to, like:

how to change the banner that Sendmail spits out
how to make it listen on only one interface
how to disable the VRFY and EXPN commands

for example.

Is there a better, more up to date resource than sendmail.[org|net|com] or
should I continue to Google the net for answers?
