spamassassin is probably your best bet.  It can  be configured a number
of ways.  One way is to implement it as a milter with sendmail. 
Another, that I have used in the past, is to implement spamassassin via
procmail.  Both methods should work quite well.

Another spam fighting tool that I highly recommend in combination with
spamassassin is greylisting.  I used milter-greylist with sendmail and
it reduced spam from 3000-6000 a day to 5-10 spam a day which
spamassassin handled easily.  Greylisting actually kept my mail server
from getting stressed as it did sometimes during spam storms.
