More flexibility may be needed to counter evolving spammer techniques. Reproducible: Always Steps to Reproduce: 1.recv spam where sole content is multipart/mixed , no text , just one png viagre spam image for up25.ru type pill pushers address. 2.Try to construct filter to match. 3. Actual Results: Using customise headers is good and allows matching of X-Mozilla-Status2 to detect an attachment and Content-Type: multipart/mixed. But this is still too general. Expected Results: More flexible filter setting to enable targeting more precise filters. These guys will always come up with new tricks but at least we need the flexibility to adapt as well. Ideas : a means to detect image without body text a means to do arithmetical or logical tests:(X-Mozilla-Status2 < 1000000) (X-Mozilla-Status2 AND 1000000) as well as lexical "begins with" "ends with" "contains" etc. a filter on attachment size.
