Right, too much risk, no better results. > How I can sdo so that SA blocks the spam messages without blocking clean > messages, per domain basis?? > Thanks, > rocsca Make sure you have network tests enabled: $sa_local_tests_only = 0; If you have not already done so, consider installing DCC, Razor and Pyzor. Personally, I would see if disabling auto-whitelist helps, set use_auto_whitelist 0 in local.cf (just to see if it helps) Learn how to create custom SpamAssassin rules, here is a start: http://wiki.apache.org/spamassassin/WritingRules You should also spend some time learning about how to properly feed spam and ham to the Bayes engine. The Wiki is again a starting point. > In this days we receive many and many email containing 'SPUR-m [Sperm > pills]' phrase. > Can someone tell me how I have to block this kind of spam messages?
