This controls how long an undeliverable NDR stays in the queue. It has no effect on when the NDR is generated. > > However, I'm noticing that postfix seems to be completely ignoring this > setting.

Non-deliverable mail is returned to sender when either the remote server gives a 5xx "undeliverable" response, or $max_queue_lifetime expires. Undelivered mail will hang around in the queue if the remote server gives a 4xx "retry" response, or the remote server exists but is unreachable, or if you've set soft_bounce=yes.
