Queues that are generated by Message Queuing are referred to as system queues, internal private queues, and outgoing queues. System queues include the following types of queues:

  • Queue journals: Queue journals are queues that contain copies of all messages removed from a queue with target journaling enabled.

  • Computer journals: Computer journals are queues that contain copies of all messages sent from a computer with a request for positive_source journaling.

  • Dead-letter queues: Dead-letter queues contain messages that were sent from a computer with a request for negative source journaling and could not be delivered. Message Queuing provides a transactional dead-letter queue and a nontransactional dead-letter queue.

  • Connector queues: Connector queues are used when sending messages to foreign queues.

The computer journal and the dead-letter queues are listed in MMC snap-ins (or the Control Panel applet) in the System Queues folder.

Applications can read the messages in system queues, but cannot address messages to them.
