One option that will eliminate 95%+ spam that is available for most MTAs
is greylisting. The combination of greylisting and spamassassin blocks
nearly 100% of spam. The added benefit of greylisting is that your
system's load won't be pushed due to overhead of running spamassassin on
the vast majority of messages.
I implemented milter-greylist/sendmail/procmail on a system for a small
company and reduced the number of spam messages from around 8000 a day
to about 10 or 15 a day, and those were caught by spamassassin.
You might want to check out http://www.rulesemporium.com/ they have a
number of very good rules sets and possibly some examples that may help
you write specific rules for the spam you are receiving.
