Banning Character Sets

[Paul Hamilton]

Hi All,

We have seen a useful feature in GFI's Spam Filter Software.
They provide the client with the ability to ban character sets.
Is it possible to do this with Spamassassin by domain?
or as a feature request could the Blacklist functionality be extended
to ban specific character sets per domain?

As an example a client of ours is able to ban all emails containing any
Chinese characters, they stop in the region of 250 emails a day at their
Exchange server this way. They come from multiple sources so adding to
the SA Blacklist is not desirable to the client.

Thanks in advance

Paul H
