I may misunderstand you, but how can you tell where my mailbox resides?
If you look at my "Message-Id", you might guess that you could send to
"rbbb@proserpina.rice.edu", and you would be wrong.

I read my mail at "titan.rice.edu", but you should just send it to
"rice.edu", and let it be forwarded to whereever I happen to currently
live.  It is difficult to propagate precise information about my
whereabouts to ALL the machines on our net, and much more difficult when
you consider that I am certainly not the only user here.  It is much much
simpler to have every machine except the one where my mailbox resides boot
my mail to "rice.edu", and let "rice.edu" forward it to my home.
Obviously, we take great pains to keep rice.edu up and running, but it is
no more vital than our gateway, our line to the IMP in Austin, or the IMP
itself.

I don't see how extended domain names will help this.
