I use Linux machine in the DMZ and I installed and configured by myself
the pop beam when I upgraded my Exchange to 2000.

There are many way of doing this.
We used Solaris 8 running sendmail 8.12x.
For antivirus we put in Trendmicro Interscan Virus Wall. Sendmail is
quite a pain to configure, I was on the Sendmail newsgrp to ask a lot of
question before get it configure and work correctly, with no relay and
mailertable, smarthost etc.
One fellow in the newsgrp that correspond with me at the end choose
postfix which he said is much easier to use.
On that note I was at Sunbelt site, someone actually use Linux and was
told by an expert that he used FreeBSD which is a much secure OS. For
any OS that is put in DMZ must do hardening which can be quite
complicated. When I was doing this the general preception at that time
is NT4.0 is not secure and not suitable to put in DMZ. May be win2k is
more secure, have to do a study on that.
Make sure the mx record in DNS is configure correctly, also you must
have at least two mail relay servers to provide redundancy.

We have Exchange 2000 on our network and to increase security I'm
looking into putting some sort of mail proxy / relay agent onto the DMZ
of our firewall. The outside world will see it as our mail server and it
will relay email onto Exchange. Has anyone done this before and if so
what mail proxy / relay have you installed.
TIA
Andy
