This is a generic issue whenever you chain SMTP relays. You cannot enforce relay restrictions only at the final MTA. As you pointed out, intermediate MTAs will lose the information about the last external MTA. You must enforce relay restrictions at all border MTAs or restrict relaying to only specific recipients (which is easier said than done). -- Crist J.
