Eh, you could just port forward all "inbound" mail to the NT server
directly.
Imagine that there is a "pipe" which runs right thru your firewall. This
pipe is ONLY permitted carry (to forward and reply to) mail exchanges to the
Exchange Mail Software.
As far as the internet is concerned JUST for mail, your Exchange server is
"open". Other ports would remain "locked down"... so only MS-Exchange
exploits would be a problem...
Linux is a much better Newsgroup Manager than NT and you might want to let
it take over this responsibiluty.

Tips:
1) Run SAMBA, set up DOMAIN logins, and let NT become the "source" of
authentication. This prevents you from having to re-create all of those
accouns...
2) Use IP chains to NAT your LAN, then port forward, Exchange and POP,POP3,
SMTP, etc. "into" your NT box...
3) There is a new book out (check out amazon.com) topic SAMBA, about
integrating Linux into an environment with NT machines... I forget the name,
but it has a Black cover...
I ordered mine but have yet to receive it...
4) Take advantage of the available "automatic" firewall script generators on
the internet... for Linux...
