Hi,
I use Postfix's header checks to do exactly this. It can result in
losing some mails from mailing lists though.
My regex looks like this:
/^Subject:.*=\?(GB2312|big5|euc-kr|ks_c_5601-1987|koi8)\?/ DISCARD
NotReadable1
/^Content-Type:.*charset="?(GB2312|big5|euc-kr|ks_c_5601-1987|koi8)/
DISCARD NotReadable2
Hope this helps
