ABSTRACT:
A system and method for selectively allowing or denying access to a user coupled to an electronic communications network includes a receiver that receives an inbound message over the electronic communications network from a sender. The inbound message includes an identifier that is associated with a sender and an identifier that is associated with a recipient. The system also includes a processor that determines if the identifier associated with the recipient was previously generated by the user and is absent from a plurality of proxy identifiers associated with the recipient. The processor is further determines one of at least three security states associated with the inbound message. A first security state is indicative of allowing delivery of the inbound message to the user. A second security state is indicative of denying delivery of the inbound message to the user. A third security state is indicative of conditionally allowing delivery of the message to the user. Each of the three security states are associated with the sender identifier and the recipient identifier included in the inbound message.
