Gets or sets a value that indicates whether the queue to be installed accepts only authenticated messages.
Assembly: System.Messaging (in System.Messaging.dll)
When a non-authenticated message is sent to a queue that accepts only authenticated messages, the message is rejected. The sending application can request notification of a message rejection by setting the AcknowledgeType for the message. Otherwise, there is no indication that the message was rejected, so the message can be lost unless you send it to the dead-letter queue.
