I have had not so good experience with ready-made spam filter software, but I cant help thinking about filtering rules when I get another variation of things CIAL15 V!A6RA etc. mail headers.

It should be possible to make something like a 733T5P33CH-Parser that transforms weird characters and punctuations above them to the most likely "normal" characters and then finally we can match the result against the suspicious keywords? Have any idea or experiences already with that?
