If you requeue a message then it will return to the queue in the same
position that it was, and that may lead to the same consumer getting the
message if it goes to the front of the queue.
You could re-publish the message instead of requeueing, which will force
it to the back of the queue and hope that a different consumer gets the
message when it reaches the front. You could also publish such messages
to a different location where you guarantee that authorisation will not
In general you should try to route messages to separate queues and bind
consumers in such a way that they will only receive messages which they
are able to process.
