I've had good results scoring for the combination of windows-1256 encoding and quoted-printable. It pushes some junk over the top into spam. Admittedly a message that is mainly in a Latin character set with a quote from Arabic could be so encoded, so I don't give it a killer score, just a bump.
In my previous message some days ago I wrote about the combination of the windows-1256 character set and qp =9D between non-Arabic characters, where it would never make sense. The reply about my own message matching for mentioning =9D did not make sense since my message was not in windows-1256. If this spam technique spreads I still think it would be worth some score. A broader rule would look for an ISO encoding of the same Arabic no-space character between non-Arabic characters. Joseph Brennan Columbia U I T
