METHOD AND SYSTEM TO DISCOURAGE A SENDER FROM COMMUNICATING AN ELECTRONIC MESSAGE TO A USER

摘要

A System to update a filter to discourage a sender from communicating an electronic message to a user. The System receives a message from a sender that includes a network address of the sender and determines whether to discourage the sender from communicating a second message to the user based on input from a user. If a user indicates that the sender should be discouraged, the System updates the filter by registering the network address of the sender in the filter that is subsequently utilized to communicate a response message to the sender that includes an error code indicating that the network address of the user is an invalid network address. A System to use a filter to discourage a sender from communicating the second message to a user and a System to automatically remove a user from a mailing list are also described.
