Sorry, that was not my intention.  I was looking for a secure,
trusted, Anti-"all", pop/imap, virtual user/domain and other
fully-featured system that most IT admins might be using.  I am
guessing it is sendmail (as you also said, below) and I have been
using sendmail for a long time, but at this time, I am had problems
getting the clamav-milter and spamassassin-milter to work thus
is disabled at this time.

This is really cool!  At least this will allow me to try out different
email systems.

But for me, I thought sendmail was damn hard (still do) and yet I have
more reading to do when it comes to postfix i.e. I have to start at the
beginning.  I have found links in HowtoForge.com: "Fedora 8 Server Setup:
LAMP, Email, DNS, FTP, ISPConfig" but the "caveat" might be the use of
ISPConfig which does NOT work with Gnome's GDM - but a temporary solution
is to use /etc/desktop and KDE. Quite frankly, I am on the verge of ripping
out ISPConfig and backing out certain changes as I am beginning to suspect
that it caused other sets of problems, one which setroubleshoot is broke.
As it is, setroubleshootd and sealert runs @ 95% of CPU individually, sealert
hangs and zombies when terminated, and with both running takes 100% CPU and
both do not work anymore.  Reinstalling setroubleshoot will not fix it but
it did work BEFORE I installed ISPConfig.

Another link I found on HowtoForge.com: "Virtual Users and Domains With
Postfix, Courier and MySql" and this also looks interesting but hey - I
have done this with sendmail so I do not see the advantage of this other
that this is a different and interesting postfix implementation.

Interesting...

BETA!?!?  Uh, ok. ;)

Do you know of any setup/howto's for setting up Postfix with
MailScanner/amavisd such as you suggested?

Thanks!
