I'd recommend doing SPAM and virus filtering on the mail gateway and
http proxy, and running the firewall on a separate machine.

My favourite glueware between MTA and content checkers is amavisd-new.
It's very flexible and powerful.
I'm using postfix/amavis/spamassassin/(various AV's) in a number of
sites with great success.

Absolutely, the Linux kernel firewall is as good a stateful packet
filter as any. I don't think Fedora is the best choice for an Internet
firewall, though, simply because of its short life cycle. The last thing
you want is stale software at your perimeter. Have a look at the free
RHEL variants, or even OpenBSD, which has a way cool kernel firewall
(pf).
Cheers
