Use a Mail.app rule to stop Far East spam
Authored by: Typhoon14 on Apr 24, '03 09:19:55PM

Remember, this will be equally effective at blocking all mail
from these regions, not just spam.

Use a Mail.app rule to stop Far East spam

Should say that this does not block ALL mail from these regions,
but those that are associated with mainland china. For example,
Taiwan, country near China, would not be affected.

Use a Mail.app rule to stop Far East spam

Note that these character sets include roman characters as a subset, and many Chinese people routinely use them even when sending mail in English. It is convenient for them as they can use English, Chinese or a mixture. It isn't even just people in those countries who use these character sets either; I get mail from Chinese friends in USA and Europe who use it too. Don't block mail based on Chinese character set unless you don't want any mail at all from Chinese people. Same for cyrillic etc.

The "right" way is to measure the fraction of the email body which is in non-roman characters. I don't know if it is possible in Mail.

Quite correct.

Further, this will likely only match mail originating from mainland China (and there's 4 other, less popular encoding types just for Simplified Chinese). Mail from Taiwan will likely be in one of the Big5 encodings, Korea (where *I* see spam from) is probably EUC-KR or ISO-2022-KR, and Japan uses either SHIFT-JIS, ISO-2022-JP, EUC-JP (probably).
