You could use either SASL (smtp authentication) or pop-before-smtp, so the user POP's mail, their IP address is recorded for a small amount of time (5-10 minutes) and that IP is allowed to relay through Postfix. Cheers, Rob -- So close, no matter how far... couldn't be much more from the heart. Forever trusting who we are, and nothing else matters.
