Even simpler: stop reading the deferred queue when more than N% of
the maximal number of recipient slots is from deferred mail.
Hmm, that could work. It would be definitely useful knob for dealing
with the active-queue-full bottleneck. And if I wanted, I could set it
so low that it would even solve the delivery-agents bottleneck. Sure, it
might perhaps hamper the throughput a bit for "real" retried recipients
compared to standalone transport, but would solve my use case as well...
