Abstract: A method and system for authorizing communications sent from a sender to a recipient. The authorization system receives a communication sent from a sender to a recipient. The authorization system determines whether that sender is authorized to send communications to that recipient. If the authorization system determines that the sender is not authorized, then the authorization system sends an authorization communication to the sender. The authorization communication requests authorization information from the sender. When the authorization system receives the authorization information, it determines whether the information is correct. If correct, then the authorization system indicates that the sender is authorized and forwards the communication to the recipient. When a subsequent communication sent from the sender to the recipient is received, the authorization system may automatically determine that the sender is authorized and forward the communication to the recipient without re-contacting the sender.
