|

|
||||
;;; Commentary:
|
||||
;;; -----------
|
||||
|
||||
;;; Automatically recognize and delete junk email before it is
|
||||
;;; displayed in rmail/rmail-summary. Spam emails are defined by
|
||||
;;; specifying one or more of the sender, subject and contents.
|
||||
;;; URL: http://www.weizmann.ac.il/~eli/Downloads/rmail-spam-filter/
|
||||
|
||||
;;; Usage:
|
||||
;;; ------
|
||||
|
||||
;;; put in your .emacs:
|
||||
|
||||
;;; (load "rmail-spam-filter.el")
|
||||
|
||||
;;; and use customize (in rmail-spam-filter group) to:
|
||||
|
||||
;;; (*) turn on the variable rmail-use-spam-filter,
|
||||
|
||||
;;; (*) specify in variable rmail-spam-definitions-alist what sender,
|
||||
;;; subject and contents make an email be considered spam.
|
||||
|
||||
;;; in addition, you may:
|
||||
|
||||
;;; (*) Block future mail with the subject or sender of a message
|
||||
;;; while reading it in RMAIL: just click on the "Spam" item on the
|
||||
;;; menubar, and add the subject or sender to the list of spam
|
||||
;;; definitions using the mouse and the appropriate menu item. Â You
|
||||
;;; need to later also save the list of spam definitions using the
|
||||
;;; same menu item, or alternatively, see variable
|
||||
;;; `rmail-spam-filter-autosave-newly-added-spam-definitions'.
|
||||
|
||||
;;; (*) specify if blind-cc'ed mail (no "To:" header field) is to be
|
||||
;;; treated as spam (variable rmail-spam-no-blind-cc; Thanks to Ethan
|
||||
;;; Brown <ethan@gso.saic.com> for this).
|
||||
|
||||
;;; (*) specify if rmail-spam-filter should ignore case of spam
|
||||
;;; definitions (variable rmail-spam-filter-ignore-case; Thanks to
|
||||
;;; Ethan Brown <ethan@gso.saic.com> for the suggestion).
|
||||
|
||||
;;; (*) Specify a "white-list" of trusted senders. If any
|
||||
;;; rmail-spam-white-list string matches a substring of the "From"
|
||||
;;; header, the message is flagged as a valid, non-spam message (Ethan
|
||||
;;; Brown <ethan@gso.saic.com>).
|
||||
|
||||
;;; (*) rmail spam filter also works with bbdb to prevent spam senders
|
||||
;;; from entering into the .bbdb file. See variable
|
||||
;;; "rmail-spam-filter-auto-delete-spam-bbdb-entries". This is done
|
||||
;;; in two ways: (a) bbdb is made not to auto-create entries for
|
||||
;;; messages that are deleted by the rmail-spam-filter, (b) when a
|
||||
;;; message is deleted in rmail, the user is offered to delete the
|
||||
;;; sender's bbdb entry as well _if_ it was created at the same day.
