Patent ID: 7672998

Claim:
A computer-implemented method for controlling transmission of messages from an originator computer system through an originating mail server to a receiving mail server, a connection between the originator computer system and the originating mail server forming a sending side, the method comprising the steps of: dynamically creating a valid account name and network address pair; detecting, on the sending side, an outbound message from the originator computer system; verifying, on the sending side, an authenticity of an originator identity associated with the outbound message by comparing a mapping of network addresses with account names such that the originator identity associated with the outbound message is associated with the valid account name and network address pair; performing a quota enforcement operation based on a message count and a message limit associated with the originator identity to produce a message transmission result; and performing a selective transmit operation including at least one of: i) transmitting the outbound message from the originating mail server to a receiving mail server on a computer network if the message transmission result contains a transmit value; and ii) preventing transmission of the outbound message from the originating mail server to a receiving mail server on a computer network if the message transmission result contains a no-transmit value.
