SpamFilter

Spamfilter is a procmail script, which first filters mail through SpamAssassin (see http://www.spamassassin.org/). It then uses the headers added by SpamAssassin to further process the mail.

Mail tagged by SpamAssassin as being spam is moved to a seperate mailbox. The suspected spammer will receive a mail that his e-mail has been deleted. In this mail he is informed that he can bypass the spam filter by starting the subject field with the keyword NOSPAM. Real spammers do not read bounced messages. But legitimate senders whose mail is accidentally tagged as spam will do.

Get the SpamFilter script. The documentation is included in the header. Beware of DOS to Unix (CR-LF to LF) text file conversion when copying the script.

SpamFilter comes with an additional test script performing the same tests done by SpamFilter. It writed the results of the tests to the standard output. It can can be useful to find out why SpamFilter did move or did not move a certain message.

Get the SpamFilterTest script. The documentation is included in the header. Beware of DOS to Unix (CR-LF to LF) text file conversion when copying the script.
