How to retry send a failed msg to backend via service connector.

Hi, we are trying to make a request-response messagepattern (via MSMQ topic) that can handle exceptions in the reply from service-endpoint (backend) the same way as if backend dosen't answer.

Meaning, Neuron should put the original messages into the poison-queue (not the failed reply-message.

How do we store/find correlating request-response messages and how to republish to the correct poison-queue?
