/**
* Rejects a message sending a NACK to the message broker.

* It can be used to interrupt and cancel larg incoming messages, or return untreatable messages to their

* unhandled messages. If a publisher receives this signal, it probably needs to republish the offending messages.
*
* This shouldn't be used as a mean for selecting messages to process.
*
* The server can try to re-queue the message once (if $reQueueAgain=true). If $reQueueAgain is false or the re-queue
* attempt fails, the message will be discarded or dead-lettered. The server will try to re-queue the message
* to an alternative consumer if possible.
