I have used this combination successfully with Exim/Exiscan:
1, greylist
2, recipient checking using ldap
3, Spamassassin regex only filter -L, and add header if spam
4, DSPAM, add header if spam
5, tagged spam is sent to imap accounts which users can log in to and take
care of the spam any way they see fit, incl. the sa-learn-unlearn and dspam
learn-unlearn scripts.
That's the road map. There are lots of how-tos out there.
