If we want to pass control to the recipients but need to use a router for reasons of network efficiency, we can employ a dynamic Recipient List (249). This type of Recipient List (249) acts as a Dynamic Router (243), allowing recipients to express their preferences via control messages to the router. The Recipient List (249) stores the recipient preferences in a database or a rule base. When a message arrives, the Recipient List (249) forwards the message to all interested recipients whose criteria match the message.
