9.18.8.3 Low-level interface to the spam-stat dictionary

The main interface to using spam-stat, are the following functions:

— Function: spam-stat-buffer-is-spam

Called in a buffer, that buffer is considered to be a new spam mail. Use this for new mail that has not been processed before.

— Function: spam-stat-buffer-is-no-spam

Called in a buffer, that buffer is considered to be a new non-spam mail. Use this for new mail that has not been processed before.

— Function: spam-stat-buffer-change-to-spam

Called in a buffer, that buffer is no longer considered to be normal mail but spam. Use this to change the status of a mail that has already been processed as non-spam.

— Function: spam-stat-buffer-change-to-non-spam

Called in a buffer, that buffer is no longer considered to be spam but normal mail. Use this to change the status of a mail that has already been processed as spam.

— Function: spam-stat-save

Save the hash table to the file. The filename used is stored in the variable spam-stat-file.

— Function: spam-stat-load

Load the hash table from a file. The filename used is stored in the variable spam-stat-file.

— Function: spam-stat-score-word

Return the spam score for a word.

— Function: spam-stat-score-buffer

Return the spam score for a buffer.

— Function: spam-stat-split-fancy

Use this function for fancy mail splitting. Add the rule ‘(: spam-stat-split-fancy)’ to nnmail-split-fancy

Make sure you load the dictionary before using it. This requires the following in your ~/.gnus.el file:

     (require 'spam-stat)
     (spam-stat-load)

Typical test will involve calls to the following functions:

     Reset: (setq spam-stat (make-hash-table :test 'equal))
     Learn spam: (spam-stat-process-spam-directory "~/Mail/mail/spam")
     Learn non-spam: (spam-stat-process-non-spam-directory "~/Mail/mail/misc")
     Save table: (spam-stat-save)
     File size: (nth 7 (file-attributes spam-stat-file))
     Number of words: (hash-table-count spam-stat)
     Test spam: (spam-stat-test-directory "~/Mail/mail/spam")
     Test non-spam: (spam-stat-test-directory "~/Mail/mail/misc")
     Reduce table size: (spam-stat-reduce-size)
     Save table: (spam-stat-save)
     File size: (nth 7 (file-attributes spam-stat-file))
     Number of words: (hash-table-count spam-stat)
     Test spam: (spam-stat-test-directory "~/Mail/mail/spam")
     Test non-spam: (spam-stat-test-directory "~/Mail/mail/misc")

Here is how you would create your dictionary:

     Reset: (setq spam-stat (make-hash-table :test 'equal))
     Learn spam: (spam-stat-process-spam-directory "~/Mail/mail/spam")
     Learn non-spam: (spam-stat-process-non-spam-directory "~/Mail/mail/misc")
     Repeat for any other non-spam group you need...
     Reduce table size: (spam-stat-reduce-size)
     Save table: (spam-stat-save)
