White lists (Greylisting)
Greylisting is a prevention method that allows to filter out spammers with special programs. Graylisting is active for all the messages by default (except those specified in the white list).
The receiving mail server rejects a message, informs a sender that the message cannot be delivered immediately and asks to try again later. The sending server of a legitimate user will retransmit the message. Such mail servers are put on the white list and will be delivered without any delay.
The servers that spammers use generally will not respond, because the spammer's goal is to disseminate millions of messages quickly and not have to keep track of those failed to reach their destination.
