       Mail::SpamAssassin::Plugin::TextCat - TextCat language guesser

         loadplugin     Mail::SpamAssassin::Plugin::TextCat

       This plugin will try to guess the language used in the message text.

       You can then specify which languages are considered okay for incoming
       mail and if the guessed language is not okay, "UNWANTED_LANGUAGE_BODY"
       is triggered

       It will always add the results to a "X-Language" name-value pair in the
       message metadata data structure. This may be useful as Bayes tokens.
       The results can also be added to marked-up messages using "add_header",
       with the _LANGUAGES_ tag. See Mail::SpamAssassin::Conf for details.

       Note: the language cannot always be recognized with sufficient
       confidence.  In that case, "UNWANTED_LANGUAGE_BODY" will not trigger.

       ok_languages xx [ yy zz ... ]      (default: all)
           This option is used to specify which languages are considered okay
           for incoming mail.  SpamAssassin will try to detect the language
           used in the message text.

           Note that the language cannot always be recognized with sufficient
           confidence.  In that case, no points will be assigned.

           The rule "UNWANTED_LANGUAGE_BODY" is triggered based on how this is

           In your configuration, you must use the two or three letter
           language specifier in lowercase, not the English name for the
           language.  You may also specify "all" if a desired language is not
           listed, or if you want to allow any language.  The default setting
           is "all".


             ok_languages all         (allow all languages)
             ok_languages en          (only allow English)
             ok_languages en ja zh    (allow English, Japanese, and Chinese)

           Note: if there are multiple ok_languages lines, only the last one
           is used.

       inactive_languages xx [ yy zz ... ]          (default: see below)
           This option is used to specify which languages will not be
           considered when trying to guess the language.  For performance
           reasons, supported languages that have fewer than about 5 million
           speakers are disabled by default.  Note that listing a language in
           "ok_languages" automatically enables it for that user.

           The default setting is:

           bs cy eo et eu fy ga gd is la lt lv rm sa sco sl yi

           That list is Bosnian, Welsh, Esperanto, Estonian, Basque, Frisian,
           Irish Gaelic, Scottish Gaelic, Icelandic, Latin, Lithuanian,
           Latvian, Rhaeto-Romance, Sanskrit, Scots, Slovenian, and Yiddish.

       textcat_max_languages N (default: 5)
           The maximum number of languages before the classification is
           considered unknown.

       textcat_optimal_ngrams N (default: 0)
           If the number of ngrams is lower than this number then they will be
           removed.  This can be used to speed up the program for longer
           inputs.  For shorter inputs, this should be set to 0.

       textcat_max_ngrams N (default: 400)
           The maximum number of ngrams that should be compared with each of
           the languages models (note that each of those models is used

       textcat_acceptable_score N (default: 1.05)
           Include any language that scores at least
           "textcat_acceptable_score" in the returned list of languages
