How SpamAssassin recognize chinese character?
Hi list:
I have been using SpamAssassin for quite a while, and used SARE rules
and other custom rules. I am interested in writing my own chinese spam
rules to block chinese spam email.
I found chinese rules at
http://www.ccert.edu.cn/spam/sa/Chinese_rules.cf
and http://www.geewhiz.ca/images/b/b2/99_geewhizg_zh.cf .
My question is how SpamAssassin internally recognize the chinese
character in perl regex since all the rules are written in chinese
character (or in GB2312 character set)? why the rules is not written in
unicode charset like utf-8?
I read a lot about unicode, utf-8, perlunicode, perlre..still could not
find relevant information.
Thanks in advance!
Vincent

I really think that Vincent is looking to write rules that detect Chinese spam,
without affecting his normal Chinese nonspam mail.
Based on tone of his email being based on wanting to look for specific Chinese
text, and referencing sites that have such rules, I suspect Vincent speaks
Chinese, and receives nonspam in that language.

If you are using the perl of 5.8.0 or higher,it process the unicode
characters well.So you should not worry about that Perl how to interpret
the Chinese character.Just use the rules as normally as english language.

Hi Joh:
I am in academic enviroment, we do receive some legitemate chinese
email and the chinese rules I downloaded works well. I am just
curious how SpamAssassin or Perl interpret the rules written in Chinese?

I cheat and use an Exim acl statement to reject messages composed in
unwanted character sets. However, I don't know which other MTAs would be
able to do this, or even if this blanket approach would suit you.
