1. A method of attracting and harvesting spam messages, the method comprising: receiving, by one or more processors, one or more messages for a message relay server that (i) identifies a spam message based, at least in part, on the spam message matching one or more identification patterns for spam messages and (ii) prevents the sending of the spam message to a target destination of the spam message; relaying, by the one or more processors, a first message, included in the one or more messages, to a target destination of the first message, based, at least in part, on a determination that a pattern of the first message matches, at least in part, an identification pattern, that identifies probe messages, comprising a first identification pattern for probe messages that differentiates between probe messages and spam messages; capturing, by the one or more processors, for a relayed probe message, a second message that originated from an IP address of the relayed probe message; and processing, by the one or more processors, the one or more messages and the second message to generate an identification pattern that identities potential spam messages.
