Télécharger le paquet source milter-greylist :
milter-greylist is a stand-alone milter written in C that implements the greylist filtering method, as proposed by Evan Harris.
Grey listing works by assuming that unlike legitimate MTA, spam engines will not retry sending their junk mail on a temporary error. The filter will always temporarily reject mail on a first attempt, and to accept it after some time has elapsed.
If spammers ever try to resend rejected messages, we can assume they will not stay idle between the two sends (if they do, the spam problem would just be solved). Odds are good that the spammer will send a mail to an honey pot address and get blacklisted in several real-time distributed black list before the second attempt.
