Graylisting is a method to prevent email users against Spam. It is one type of filtering that involves the strategic temporary rejection of a sender based on that sender's IP address and additional routing information.

The server which uses a Graylisting strategy will take the sender's IP address and other routing information attempt to match it against a database.
