In detail
The counterpart of rabbitmq-success and the more valuable of the two for deliverability work: it carries the state and outcome of every attempt that led to the failure. Verified on the stand — an injected message to a domain with no mail server arrived here within seconds, carrying state: dns, result: error, status: 5.4.4 and the engine's own description.
