No, I didn't work on that but thought I'd reply with what I finally did for spam on my xmail system. I finally did make spamassassin work on my win2k server with considerable effort. But I didn't like it very much. I felt like it involved too much effort to maintain the rule base and it looked to me like it was going to be difficult to make the service work. Also, I don't have much confidence that future development on SpamAssassin will be Windows friendly. We use Sniffer by http://www.sortmonster.com/MessageSniffer/ on our Imail system called by DECLUDE and it is very effective for us. Our top tests for spam in June to date: Test All Mail SPAM ------------- -------- ------ SNIFFER 53.98% 95.2% EASYNET-DNSBL 40.34% na SPAMCOP 32.76% na BADHEADERS 25.22% na REVDNS 21.62% na NOABUSE 19.62% na NOPOSTMASTER 18.82% na This means that of all messages processed 53.98% failed one or more SNIFFER tests and of those failed messages 95.2% were actually SPAM messages that were intercepted and deleted before delivery to the recipient. The 4.8% mostly is handled by exception rules and for the most part is mailing list messages. EASYNET-DNSBL and SPAMCOP are both ip4r DNS tests (see http://www.declude.com/junkmail/support/ip4r.htm for a list and brief description). BADHEADERS test checks for certain header formatting. REVDNS checks whether a reverse dns exists for the sender. NOABUSE and NOPOSTMASTER test the presence of those accounts on the sender's system. We run a total of 65 tests but really I could eliminate most of them except SNIFFER and achieve almost the same result. It is $25 per month for the service but the rule base is updated frequently - sometimes several times in one day. I thought when I get a bit more time I'd finish the filter program that calls SNIFFER and make it available to the community.
