title: RabbitMQ - Find out on publisher side that a message has been acknowledged by the consumer(s)
body: <p>I am using RabbitMQ as a MQ broker. Is it possible to get a notification that a certain message has been acknowledged by all queues? That is, if it was sent to 5 queues, we get a notification after the acknowledgment of the last/5th consumer.</p>
  
  <p>I know you can introduce <code>reply-to</code> queues, but that's not what I am looking for. I don't want to force the consumer to send <em>an acknowledgment message</em> to some queue after acknowledgment.</p>
  
  <p>Is it also possible to continue this follow-up after a broker and/or publisher restart?</p>
