True, but they would have to find out what they were to do it. It would not prevent you from being an open relay, but it would make it harder. You could also ensure that the reply to was the same as the sender's email address, in that way they could not get responses back to their email, so it would be that much more useless to them to use you as an open relay. There's easier targets out there.
