title: spamassassin rule to give a higher score to a certain language
body: <p>Is it possible to give a score to e-mails written in a specific language?</p>
  
  <p>Background info:
  In specific cases I use score rules in the .spamassasin/user_prefs file. Some of our e-mail accounts receive extraordinary many spam messages in the Chinese language; other accounts in the Russian language. I'd like to make the score for these languages a little bit higher, on user account level, so using the user_prefs file in only certain mail accounts.</p>
  
  <p>I know about the method using ok_languages (in local.rc) in combintation with UNWANTED_LANGUAGE_BODY in user_prefs. However this blocks (or scores) ALL languages not mentionned in ok_languages. That's the reverse of what I want to acheive: I want to give a little bit higher score to messages from a single language, not all languages not mentionned in ok_languages. 
  We receive mail from all over the world so that's why I don't want to block all the messages written in a certain language, I only want to make the score a little bit higher for messages written in a certain language, still accepting mail from all other languages. How can I do this in Spamassasin?</p>
