Abstract
The spam blocker monitors the SMTP/TCP/IP conversation between a sending message transfer agent MTAand a receiving message transfer agent MTA; catches MTA's IP address IP, MTA's declared domain D, from-address A; to-address A, and the body of the message; and uses this source and content information to test for unsolicited messages. It alters the conversation to reject, divert or intercept the message if the message is suspected of being unsolicited.
