Lately the amount of spam with russian encoding\/charset that I was getting had increased significantly. Spamassassin’s configuration options “ok_locales” and “ok_languages” were not enough because I didn’t want to whitelist some language, but I just wanted to blacklist some.<\/p>\n
So the solution for my problems was the addition of the following lines in the configuration of spamassassin:
\n
header LOCAL_CHARSET_RUSSIAN Subject:raw =~\/\\=\\?koi8-r\\?\/i\nscore LOCAL_CHARSET_RUSSIAN 7\ndescribe LOCAL_CHARSET_RUSSIAN Contains russian charset that is not acceptable<\/code2><\/pre><\/p>\n If you want to add even more charsets:
\nheader LOCAL_CHARSET_BLOCKED Subject:raw =~\/\\=\\?(koi8-r|windows-1251)\\?\/i\nscore LOCAL_CHARSET_BLOCKED 5\ndescribe LOCAL_CHARSET_BLOCKED Contains charsets that are not acceptable<\/code2><\/pre><\/p>\n Be VERY careful with these rules if you place them in the global config (\/etc\/spamassassin\/local.cf) because if any of your users are getting emails in russian those emails will be probably marked as spam!!<\/p>\n","protected":false},"excerpt":{"rendered":"
