ELECTRONIC MESSAGE DELIVERY USING A VIRTUAL GATEWAY APPROACH

摘要

Message delivery approaches are disclosed in which senders can define filters with associated actions for specified messages. Senders dispatch messages to a processing system, which evaluates the filters against the messages. If a match occurs, the processing system performs the specified actions. In one embodiment, the processing system can send the same message multiple times to different receiving systems, and can modify the source address and outbound interface of the message for each receiving system. Further, the source address or interface may be modified in response to external events, such as a receiving system blocking another copy of the message. A single message processing system can appear as a large number of virtual message sending gateways, increasing the chance that a particular message will arrive at its destination unaffected by message blocking technologies at the receiver. For bulk mailers, different filters can be associated with different communication campaigns.
