I recommend bogofilter for per-user filtering. Spamassassin is also highly recommended for site use. I tend to dislike DNS-based filtering because it has a high rate of false positives, and it causes your users to lose legitimate mail if it's rejected at the mail server. With bogofilter or SA the mail is tagged with a header that the user can then filter into a spam mailbox and review for false positives (or delete on sight if they really want to). Kris
