Usage Note

Remarks

We need to know if an exception was a business/application error (i.e. the message was sent to the server and the server rejected it) to place it into the dead-letter queue. However, if the exception is merely an indication of a communication exception (timeout due to slow send, proxy error, etc.) then we don't want to pollute the outbound queue, rather we want to keep it - pause for a period of time - and retry
