I get many spams with all garbage characters in the subject (the entire email is garbage as far as I'm concerned). Here is an example:
ªÂó║ ┴°┴ñ ▒·▓²ÃÐ ÃÃ║╬©ª ┐°Ã¤¢├│¬┐õ? ©░° ▒Ý╝¸ÃÐ░¸┐í ÃÃ┴÷©ª ┴ª░┼ÃÏ¥▀ Ãı┤¤┤┘ 0,.0 g
Here is KS_BL_TOKENS for this email:
Content-Type: 0.4000,multipart: 0.4000,alternative: 0.4000,boundary: 0.4000,219: 0.4000,DF9: 0.4000,–D: 0.4000,Content-Transfer-Encoding: 0.4000,quoted-printable: 0.4000,text: 0.0580,html: 0.1027,new: 0.0727,uid: 0.0238,bufer: 0.9900,626: 0.9900
KS_BL_PROB is 0.0034. So, this email makes it through the filter. I have KS_BL_IGNORE setup to ignore most of the MIMIE/HTML tokens, but kSpam seems to be ignoring KS_BL_IGNORE :-) (see my other post: http://www.openntf.org/Projects/pmt.nsf/b521bae9087a360985256bed004b4ec4/504c928fbfbd9f948625707c0037749c!OpenDocument )
There must be a way to block this type of email with a REGEX rule. ( The Bayesian filter in my brain tells me there is only a 0.0001 probability of me being able to write it ! )
Any ideas?
