Gets or sets a value that indicates whether the message was (or must be) authenticated before being sent.
Assembly: System.Messaging (in System.Messaging.dll)
The message queue is filtered to ignore the property.
The property specifies whether the message needs to be authenticated. If the sending application requests authentication, Message Queuing creates a digital signature and uses it to sign the message when it is sent and authenticate the message when it is received.
If is false and a message is sent to a queue that accepts only authenticated messages, the message will be rejected when it reaches the queue.
You cannot determine if a message failed authentication by looking at its properties. Message Queuing discards such messages before they are delivered to the queue. However, you can request that an acknowledgment message be sent if a delivery failure prevents a message from arriving in the queue.
