As for what settings work better with high-volume receivers, I
suggest a search query for "aol postmaster", "yahoo postmaster" etc.
With per-destination recipient limit > 1, destination = domain,
and different destinations(=domains) are delivered in parallal
subject to concurrency limits. This enforces fairness between
different destinations(=domains).
With rate delay > 0, per-destination(=domain) concurrency is 1.
With per-destination recipient limit = 0, destination = recipient,
and different destinations(=recipients) are delivered in parallal
subject to concurrency limits. This enforces fairness between
different destinations(=recipients).
This setting is used by the local delivery agent.
