Summary milter-greylist is a stand-alone milter that implements greylist filtering
Description 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 reject mail temporarily on a first attempt, then 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 a honey pot address and get blacklisted in several real-time distributed black lists before the second attempt.
