If you're sending mail to u@A.B.C.D.E, why should the server for E care about A? It ought to hand over the message to a server for D, and so on, until a server for the B domain gets it and figures out who A is. For the E server to find a shorter routing, or to send directly to A, is just an optimization that should be used when possible but not insisted upon. I think the Internet has it all wrong. But then again, I'm a UUCP user, what do I know? Can you imagine, the US Post Office returning mail undelivered because it hasn't heard of some little town in Yugoslavia, rather than simply handing over the letter to the Yugoslavian Post Office and letting it figure out where to deliver it? Postal addresses are domain-based too. -- Rahul Dhesi UUCP:!{iuvax,pur-ee,uunet}!bsu-cs!dhesi
