[rabbitmq-discuss] Dead Lettering queries

[Kwstantinos Polydwrou]

So this would mean that I need a mechanism on my Consumer side (application
B) which will do the following:
- rejecting the message (based on some logic) and
- setting the requeue flag to false.

Thanks for the insight Emile, much appreciated.
