I use a old junky desktop system with linux and postfix on it to accept mail
from the world (from the dmz) then relay it to an exchange server (on the
internal net).
As a plus the postfix system filters lots of nasty attachments, and spam. se
the following for more info..

as for outlook web access id follow ms guidelines... and search the mskb,
see the following for starters.

The LAN Administrator set up an Exchange server and placed it inside the
firewall - opening ports for SSL and SMTP to the Exchange box from the
outside world. I want to move the Exchange services to the DMZ. I'm not
that familiar with Exchange 2k specifically but am used to being able to
split out services from mail servers (IE. put WebAccess and SMTP gateways)
and place vulnerable items in the DMZ or if not place the whole Exchange
server in the DMZ. The LAN admin is concerned because the Exchange server
has to see the domain controller on the inside net. How have others handled
this setup?
Thanks in advance
Nicole
