             Summary: Extend Camel RabbitMQ with guaranteed delivery (basic.return)
                 Key: CAMEL-10239
                 URL: https://issues.apache.org/jira/browse/CAMEL-10239
             Project: Camel
          Issue Type: New Feature
          Components: camel-rabbitmq
    Affects Versions: 2.17.2
            Reporter: Florian Gessner


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.
