I highly recommend the combination of postfix, amavisd-new,
spamassassin, and clamav.  I followed the process documented at
http://www.fatofthelan.com/articles/articles.php?pid=22

I'm using this for my home email server and have found it to be very
good.  I haven't had any false positives on spam or viruses yet.  If
anything, the suggested value of 5.0 for $sa_tag2_level_deflt is a bit
too conservative, and i've played with bumping it up a bit at a time
(i think my home server is around 6 or 7 now).

(I'm cc-ing the mailing lists in case the link above is useful to
anyone.  It's targeted at Debian, but should work extremely well on
SuSE and other distributions.  All of the above software is available
on SLES9 and SuSE Pro 9.2.)
