A method, apparatus, system, and signal-bearing medium that in an embodiment enforce ordering of messages sent from a queue to clients. If a total order indicator is on for a queue associated with a get message request, the next message is sent from the queue to the client if the queue does not have an associated in-doubt transaction. An in-doubt transaction may be a transaction for which the client has not received a commit request. In another embodiment, an authorized client is selected and messages are only sent from the queue to the authorized client.
