Sorry...my inbox with over 17,000 e-mails bit the dust before I
could download and implement that last version of an anti-Chinese
Spam Filter someone had posted. I am DELUGED with this junk, and
would sure appreciate it if whoever made that post could send it
along again. I believe it "addressed" pulling the ".cn" from
the "Received:" lines????? Most regular "From:" lines in these
junk mailings are bogus.
I have a filter recipe on my site that checks for characters
with the high-bit set (CHR(128)..CHR(255)). If an email is
more than 5% high-bit characters, it's trapped. The filter will
count actual high-bit characters and "quoted-printable" versions
thereof. The filter is on my website (see sig). Click on
the item about filtering Chinese spam.
Booby-trap warning... In order to trap high-bit characters,
the filter must list them. Be careful that the editor you use
can handle high-bit characters. vim in strict vi-compatable mode
is OK, but native vim mode has problems. If you see the characters
as "\0xC0", etc, you're OK.
