:) On sending this message, I got hit by the Australian Antartic Divisions mail server, suspecting I was spam. Their handling was nice, automaticly replied to an address it didn't recognise sending a 'reply to confirm you're not spam' message. That would work with your concept too, and is better than just confirming the domain exists. Account 1: CF(or other) checks this mail, if sender is not in DB: Send 'Confirm you're not spam' email requesting a resend with a UUID in the message (store the UUID in a DB with the sender address, and authorised set to false). If sender is in DB check to see if authorised is true, if so pass message to account 2, otherwise: search message for the DB stored UUID, mark the sender as authorised if found, otherwise re-send 'Confirm you're not spam' with the UUID in message. -Matt
