That sounds great. I personally use the following technique, which is
also simple and which, until last week, caught something like 95% of
the spam. The idea is simple: most spammers (until last week at
least :-) don't bother putting your e-mail address in the "To:" (or
"Cc:", or whatever) field. They just use a unique message for
everybody. So, *after filtering all mailing-lists* (that's important,
since mailing-lists also don't put your address in the headers), I
flag all mail which is not explicitly sent to me as spam. My .gnus
file contains the following:
----------------------------------------------------------------------
;; Regexp matching all my e-mail addresses
(defconst my-email (regexp-opt '([...] all my e-mail addresses)
t))
;; Regexp matching a "Delivered-To:" header, apparently automatically
;; added by my mail server.
(defconst delivered-to-re
(concat "^Delivered-To:\\s +" my-email))
(defun no-spam-p (arg)
(save-excursion
(goto-char (point-min))
(or (re-search-forward no-spam-re nil t)
(condition-case nil
(progn
(while (and (re-search-forward my-email)
(progn (beginning-of-line)
(looking-at delivered-to-re)))
(goto-char (match-end 0)))
t)
(error nil)))))
(setq nnmail-split-rule
`([...] filters for *all* mailing-lists
("mail.misc" ,(function no-spam-p))
("mail.spam" "")))
----------------------------------------------------------------------
