bounces are a whole area to be deciphered. Return receipts are a
potential privacy concern --- there should be a mechanism to request one,
but the receiver should have final say on whether it's returned or not.
And it sounds like it would be spammers heaven to test email addresses
That is why most of us turn off SMTP's VRFY and EXPN.
But then, OTOH, if I could test that the sender's email address was valid
and the one they were assigned by their provider, it'd be harder for
spammers - they can't fake addresses any more, and so I can filter on it
