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

	 loadplugin	Mail::SpamAssassin::Plugin::TextCat

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

       You can use the "ok_languages" directive to set which languages are considered okay for
       incoming mail and if the guessed language is not okay, "UNWANTED_LANGUAGE_BODY" is

       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 and can also be used in rules for
       scoring. 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,
       no action is taken.

       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 body text.

	   Note that the language cannot always be recognized with sufficient confidence. In that
	   case, no action is taken.

	   The rule "UNWANTED_LANGUAGE_BODY" is triggered if none of the languages detected are
	   in the "ok" list. Note that this is the only effect of the "ok" list. It does not act
	   as a whitelist against any other form of spam scanning.

	   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.

	   Select the languages to allow from the list below:

       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: 3)
	   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 completely).

       textcat_acceptable_score N (default: 1.02)
	   Include any language that scores at least "textcat_acceptable_score" in the returned
	   list of languages.
