most Linux distributions do a "base install" in quite a similar interactive,
graphical way as Windows does. SuSE takes it with the YaST configuration
utility yet a step further away from plain Linux towards a Windows-like
graphical administration. That's why some people love it and others hate it.
Especially it allows a point and click installation of
Postfix/AMaViS/SpamAssassin and the latest SuSE 9.1 (which I didn't try yet)
even contains the ClamAV virus scanner. You then have to modify Postfix's
configuration to forward mails to Exchange. The Postfix/AMaViS combination
has a drawback compared to Sendmail/Milter that you cannot reject spam. You
have to accept it and then decide whether to bounce, drop, quarantine or
deliver it.

Having a fixed, public IP pointing to your mail server in the DMZ saves you
from my troubles with NAT and DynDNS.
