A Broker will not forward a delivered document to other Brokers in a territory unless the document is addressed to a client by its fully-qualified client ID (in the form /territoryName/BrokerName/ClientID). If a Broker receives a delivered document that is addressed to an unqualified clientID, it delivers the document locally. If the addressee does not exist on the local Broker, the document is sent to the dead-letter queue (if one is configured) or is discarded.
