If you have Declude JunkMail Pro, then the custom filters shared on my site are all generally good at detecting this sort of thing. This one in particular would have been it by DYNAMIC, FOREIGN, TLD-WESTERNEUROPEAN, and TLD-MIDDLEEASTERN for a total of 9 points (or 90% of fail weight according to recommended scoring) between those filters alone.

The subject is also base64 encoded Latin-1 (normal text), and that can be filtered as well, though there are some rare occurrances where this can be used with foreign languages utilizing high-bit characters.

SUBJECT 8 CONTAINS iso-8859-1?b?
