If you're going to do that, you may as well just have an SMTP command CALL-ME-BACK. You would get a connection from a server trying to deliver mail. It would ask CALL-ME-BACK?. If the receiver answered OK. It would disconnect. The receiver would then connect to the sender. There's an existing SMTP command to swap roles which it would do and then start receiving the email. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
