Yes, I know they can today.  My point is that with a registrar based
system, they cannot, because they cannot be registered as valid mail
servers.

Correct, but MX's (mail servers) have static assignments, unless you
change DNS every time.  Running MX's on dynamic IP's to receive mail
would be quite silly.
