Datagram Service Endpoint Over MSMQ Topic

So, I've got a WCF service that is configured for one-way messaging.  I've got it configured as a service endpoint, the message type is set to datagram, and a service connector is enabled.  Note that the service endpoint is attached to a transactional MSMQ topic.    I was testing out scenarios when the endpoint bombed and noticed that it will not be subject to retries.  It behaves as if the message has been delivered and that's it.  Doesn't matter if a fault has been generated or not from inside the WCF service.

In my opinion this shouldn't happen, but I want to get your thoughts on why it is.  Seems to me no matter if it's one-way or request/reply, the durable transport layer should back me up.

I will confirm with dev but I do not believe the message is supposed to be rolled off the queue if and endpoint error occurs. Never actually heard of it happening. Usually the opposite is a problem Fault has been left as the error mode so the message never leaves the queue.

Will verify that it's not different for Datagram.
