9 loadplugin Mail::SpamAssassin::Plugin::TextCat
10
12 This plugin will try to guess the language used in the message body
13 text.
14 You can use the "ok_languages" directive to set which languages are
16 considered okay for incoming mail and if the guessed language is not
17 okay, "UNWANTED_LANGUAGE_BODY" is triggered.
18 It will always add the results to a "X-Language" name-value pair in the
20 message metadata data structure. This may be useful as Bayes tokens and
21 can also be used in rules for scoring. The results can also be added to
22 marked-up messages using "add_header", with the _LANGUAGES_ tag. See
23 Mail::SpamAssassin::Conf for details.
24 Note: the language cannot always be recognized with sufficient
26 confidence. In that case, no action is taken.

29 ok_languages xx [ yy zz ... ] (default: all)
30 This option is used to specify which languages are considered okay
31 for incoming mail. SpamAssassin will try to detect the language
32 used in the message body text.
33 Note that the language cannot always be recognized with sufficient
35 confidence. In that case, no action is taken.
36 The rule "UNWANTED_LANGUAGE_BODY" is triggered if none of the
38 languages detected are in the "ok" list. Note that this is the only
39 effect of the "ok" list. It does not act as a whitelist against any
40 other form of spam scanning.
41 In your configuration, you must use the two or three letter
43 language specifier in lowercase, not the English name for the
44 language. You may also specify "all" if a desired language is not
45 listed, or if you want to allow any language. The default setting
46 is "all".
47 Examples:
49 ok_languages all (allow all languages)
51 ok_languages en (only allow English)
52 ok_languages en ja zh (allow English, Japanese, and Chinese)
53 Note: if there are multiple ok_languages lines, only the last one
55 is used.

125 inactive_languages xx [ yy zz ... ] (default: see below)
129 This option is used to specify which languages will not be
130 considered when trying to guess the language. For performance
131 reasons, supported languages that have fewer than about 5 million
132 speakers are disabled by default. Note that listing a language in
133 "ok_languages" automatically enables it for that user.
134 The default setting is:
136 bs cy eo et eu fy ga gd is la lt lv rm sa sco sl yi
138 That list is Bosnian, Welsh, Esperanto, Estonian, Basque, Frisian,
140 Irish Gaelic, Scottish Gaelic, Icelandic, Latin, Lithuanian,
141 Latvian, Rhaeto-Romance, Sanskrit, Scots, Slovenian, and Yiddish.
142 textcat_max_languages N (default: 3)
144 The maximum number of languages before the classification is
145 considered unknown.
146 textcat_optimal_ngrams N (default: 0)
148 If the number of ngrams is lower than this number then they will be
149 removed. This can be used to speed up the program for longer
150 inputs. For shorter inputs, this should be set to 0.
151 textcat_max_ngrams N (default: 400)
153 The maximum number of ngrams that should be compared with each of
154 the languages models (note that each of those models is used
155 completely).
156 textcat_acceptable_score N (default: 1.02)
158 Include any language that scores at least
159 "textcat_acceptable_score" in the returned list of languages.
