After deleting a subscribed email address with a non-existing domain from a list without automatic bounce processing configured, for which Mailman obsessively retried delivery every minute while ignoring all the other queued posts, I see up to 50 deliveries per second.

Just to confirm (probably ad nauseam for the regulars out here) that a separate Postfix instance with dns lookups disabled (+ automatic bounce processing) is the way to go.
