RBL lookups are "expensive" for both the RBL service and for your
MTA (high query latency ties up more processes). So the later,
the better, in the hope that cheaper restrictions (or whitelist
criteria) can reach a definitive accept/reject verdict first.
So even with recipient restrictions, apply RBLs as late as possible.
