I got a lot of it from the supplied docs, online at
http://www.postfix.org/documentation.html but IIRC supplied in the CentOS
RPM (which was what I was working with on my test machine, to match the
CLUE server). Looking back in the mailing list archives: I see
http://linuxmafia.com/kb/Mail - but IIRC, what it points to is a bit
out-of-date. I found a lot of articles on the web - seems to be a popular
topic. Just keep in mind when reading what you find that postfix has had
changes in options, and some of the older stuff won't work, but the
concept is still valid - just needs to be implemented in a different
place.

Cheaper than free? Wow! :) I thought it was only OpenBSD that was
supposedly more secure.

IIRC, I just set up what I needed in /etc/hosts. Just be sure you set the
search order correctly in ... (scratches brain) ... nsswitch.conf(?).

I'll tar up the config files we use for CLUE, and send them over to you.
Just keep in mind I'm no expert on the subject.
