blocking spam with foreign language or alphabet or characacter
sometimes we get spam of foreign language that we don’t understand. we don’t even know the alphabet, very annoying. there are plenty of them, some from romania, china or greek. we can set spamassassin to give them higher score and then treat them as spam. here’s how to do it (tested on 3.1.4) :
1. $vi /etc/mail/spamassassin/init.pre
and add this line:
loadplugin Mail::SpamAssassin::Plugin::TextCat
save and exit
2. $vi /etc/mail/spamassassin/local.cf
and add these lines (the 2nd line adjust to your language) :
ok_locales en
ok_languages en id
save and exit
