P.S. It's an interesting thought. The only approach to a solution I could imagine is that the whole address would have to be passed in the MX query.
Once upon a time (1987) there was this experimental facility called MB (mailbox) records which did exactly that. Unfortunately, they never caught on in any real way, and the only historical mark that they seem to have left is the rather odd way in which we express the RNAME (mailbox of the responsible party) in an SOA record. Maybe it's an idea whose time has come again. How many years would it take to have a meaningful rollout if we start now? 10? 20? OK, nevermind then. :-P ---Rob
