I'm using Messagewall.


Linux box in DMZ filtering spam/virus/content/RFC compliance which then
passes "ok" mail onto exchange on the internal network.
This way, only one host needs inbound port 25 from your DMZ.

There have been a few issues that I have had to iron out, but its working
great now (blocked thousands of MyDoom emails during the SMTP conversation
so it gets nowhere near exchange) and its completely free.

Even with all that I don't know if I would ever recommend putting my mailbox
server out in the DMZ. Maybe and OWA server or SMTP Gateway, but with a
single server doing all, keep it on the trusted network...

You need to provide more information:

1) What sort of clients will be hitting your server (POP3/SMTP, IMAP, full
exchange clients, OWA)
2) Are these going to be mobile (offsite)users, and if so, how are you going
to give them access?

Also, what are your security requirements?

Im trying to decide whether to put my exchange 2003 server inside the
network and map port 25 or put it on the DMZ.  Any recommendations?
