Since I've restricted my use of greylisting to a subset of clients
-- virtually all of which can be expected to be illegitimate -- I
didn't see any real need to train Postgrey to bypass any of them.

I suppose a counterargument could be made that since current spam
zombies almost never retry after an initial temporary delivery
failure, spam sites aren't going to build up a track record of
successful deliveries, so they won't get auto-whitelisted anyway,
so there's no point in disabling the auto-whitelisting feature.
