This is not recommended, because it might cause a cycle. If a message
finds itself routed to a queue where it has already been due to
dead-letter handling then it will get dropped. You will see a message in
the logfile to this effect.

It is not clear what value you will get from dead-lettering by
automatically requeuing to the main queue. Dead-lettering is supposed to
be a last resort in case of exceptional circumstances. If you are not
dealing with an exceptional condition then design your message flow
