I've been using recipient verification for some time with good

accepting.
Recipient verification is intended for your own recipients, such as
a mail gateway in front of a downstream internal mailstore.
If you're doing recipient verification on outgoing mail, please don't.
I'm using the "reject_unverified_recipient" parameter on all mail. That
way when a user mistypes a recipient address they get instant feedback -
if they're told "message sent" then it actually got somewhere (unless
the remote server swallows garbage recipients).
My question is how to tune it - my first guesses involve
"address_verify_poll_count" and "address_verify_poll_delay" but I don't
want to make adjustments blindly.
