The default address verification probe address is <postmaster@$myorigin>.
Should it perhaps be "<>" which actually tests whether the sender address
is valid for bounce deliveries and avoids the latency of a possible
reverse probe. Also sites not using sender verification don't get
surprising whitelisting of <postmaster@$myorigin>, even if such
whitelisting is a good thing!
