Use header_filter_rules (on the admin Privacy options... -> Spam filters page. A regexp of ^subject:\s*(\(no subject\))?\s*$ will match messages with an empty Subject: header or literally '(no subject)', but it's more complicated than that because the message may have no Subject: header at all. To account for that you need three rules. The first of these has the regexp above with an action of discard. The second has the regexp ^subject: and an action of accept to accept messages with Subject: headers that didn't match the first rule, and the third has the regexp ^.*$ and action discard to discard all messages that got past the first two, i.e. those with no Subject: header at all. If you already have header_filter_rules, these three are added after the others. Otherwise, they are the only rules. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
