Recommend you implement greylisting along with spamassassin.  You can do
this using your favorite MTA.  I have used sendmail in the past with
miltergreylist,  and spamassassin via procmail.   There are many ways to
implement these so pick out one of the many how to's on the web and
setup a test system.  

The benefit of greylisting is that you won't incur the high overhead of
running spamassassin on all the spam.  At times I would see the email
server almost get overwhelmed by spam storms.  After implementing
greylisting it never broke a sweat.
