8.18.5.9 spam-stat spam filtering

See section 8.18.6 Filtering Spam Using Statistics with spam-stat.

Variable: spam-use-stat

Enable this variable if you want spam-split to use spam-stat.el, an Emacs Lisp statistical analyzer.

Variable: gnus-group-spam-exit-processor-stat

Add this symbol to a group's spam-process parameter by customizing the group parameters or the gnus-spam-process-newsgroups variable. When this symbol is added to a group's spam-process parameter, the spam-marked articles will be added to the spam-stat database of spam messages.

Variable: gnus-group-ham-exit-processor-stat

Add this symbol to a group's spam-process parameter by customizing the group parameters or the gnus-spam-process-newsgroups variable. When this symbol is added to a group's spam-process parameter, the ham-marked articles in ham groups will be added to the spam-stat database of non-spam messages. Note that this ham processor has no effect in spam or unclassified groups.

This enables `spam.el' to cooperate with `spam-stat.el'. `spam-stat.el' provides an internal (Lisp-only) spam database, which unlike ifile or Bogofilter does not require external programs. A spam and a ham processor, and the spam-use-stat variable for spam-split are provided.
