> So far camel-rabbitmq supports publisher acknowledgements to ensure that a 
> massage was delivered to the brokers. However this does not guarantee that 
> the message is delivered to queue (https://www.rabbitmq.com/confirms.html - 
> 'When will messages be confirmed?').
> To implement guaranteed delivery publisher acknowledgements have to be 
> activated together with a *return listener* and publishing messages as 
> mandatory.
> In this case the basic.return will be returned to the publisher before the 
> basic.nack or basic.ack. Only in this case we can be sure that the message is 
> really delivered to the configured queue (or fails if no queue is available).
> As a solution I provided a pull request on github together with integration 
> tests.
