Enterprise Integration Patterns: Designing, Building, and Deploying Messaging Solutions (Addison-Wesley Signature Series (Fowler))

A dynamic Recipient List (249) is the combination of two Message Routing (78) patterns. A Recipient List (249) is a router that propagates a single message to a set of recipients. The main difference between the Recipient List (249) and a Publish-Subscribe Channel (106) is that the Recipient List (249) addresses each recipient specifically and therefore has tight control over who receives messages. A Dynamic Router (243) is a router whose routing algorithm can change based on control messages. These control messages can take the form of subscription preferences issued by the subscribers. A dynamic Recipient List (249) is the result of combining these two patterns.
