Is the short circuit plugin available yet?

[Robert Nicholson <ro...@elastica.com>]

I'm looking to run SA on some mailing list mail that's constantly  
getting bombarded by asian spam.

So I would like the check to be as efficient as possible such that as  
soon as I know the mail has asian character sets or unwanted language  
I don't want it to check
any more. Any chance I can short circuit the additional checking once  
I know the mail is likely to be asian or unwanted language?

Don't limit yourself to options within SA if you can do MTA checks. As
a slash-and-burn tactic you can RBL large regions of asia (using e.g.
cn.countries.nerd.dk, tw.countries.nerd.dk)

Of course, that won't catch asian-language messages originating
elsewhere, and isn't language-sensitive.

You might also want to take a look at milter-regex. Here's what I use
on my MTA:

 reject "Sorry - only English spoken here"

  header /Subject/i       /=[?](KOI8-[RU]|GB2312|GB2312_CHARSET|ISO-2022-JP|SHIFT[-_]JIS|BIG5|WINDOWS-125[15])[?][QB][?]/ie
  header /Subject/i       /charset=(3D)?"?(KOI8-[RU]|GB2312|GB2312_CHARSET|ISO-2022-JP|SHIFT[-_]JIS|BIG5)/ie
  header /Subject/i       /[�-�]{6}/e
  header /Content-Type/i  ,text/(plain|html); *charset="?(KOI8-[RU]|GB2312(_CHARSET)?|ISO-2022-JP|SHIFT[-_]JIS|BIG5),ie
