Rhino.Esb + MSMQ: silent failures when permissions are lacking

[Dan Ling]

I've noticed that sending messages to a remote private queue silently fail when lack of permissions is blocking them.  I would like my application to be able to display or log error messages in this situation.  Is this possible with the current implementation of RSB?  

So far, the only way I've found to programatically detect this scenario requires modifying RSB, by enabling dead letter queues by adding a line to MsmqMessageBuilder.cs

message.UseDeadLetterQueue = true;
