Most software that works with Un*x mail expects to see good old
sendmail, so the admin burden of working with it is minimal.
Exim and postfix provide accurate sendmail emulation, though.
milter.org has many recipes for filtering, virus and worm checking,
and spam fighting.

Plan to spend [ length of time ] downloading, compiling, configuring,
and troubleshooting patches in order to make qmail interoperate
with other software.
If you want to see a bunch of tweaky little sysadmin projects, do
a web search on the name of each program you want to run +qmail.
Sure you want to run it? You can't get a pre-fixed qmail from
another site because of the licensing, so don't try.

Even if you decide to use sendmail or Exim as your internal mailer,
a stripped-down, featureless, secure Postfix gateway for mail
entering or leaving your site is a good idea.
Postfix's capability for content filtering is limited:
Marc Merlin runs exim. Game over, exim wins.

I would recommend postfix or exim. Postfix is my MTA of choice
because of its simplicity and strict security policy where nothing
runs as root that doesn't have to. But if you really need exim's
features then you should probably pick it. Consider using exim
or sendmail on your internal mail server and Postfix on your mail
gateway to get the best of both.
