A Greylist (also spelled Graylist) is a method of defending electronic mail users against e-mail spam. If a message arrives from an address or domain that was previously entered on the list, it will be quarantined and then delivered to the subscriber only if the sender attempts to send the message again within a certain period of time. Once a sender has been recognized as legitimate, its address is removed from the list and future messages from that address can pass through the filter unhindered and thus delivered.
