No, that's not how it's meant to work. But I doubt there's a bug in this 
area.

Probably the problem that you have is that when the message is dead 
lettered it is published to the DLX with its original routing key - I 
would guess that when publishing via an exchange you are using a routing 
key that is also bound on the DLX. Does that sound plausible?

If this is the problem, you might find that the 
x-dead-letter-routing-key argument is the solution.
