Spamresponder is a very simple and radical spam filter that combines DNS validation with the challenge/response approach. It goes through the mail messages in /var/mail/$USER, looking for specific "trusted" strings in the header and body parts of the mail. It deletes and sends an automatic reply to messages which have no "trusted" strings inside them. Those replies will include one of the "trusted" strings, so the recipient just needs to reply to this confirmation message. The MailFrom-address of an email containing a trusted string becomes a trusted string itself
