That's all fine and good once the mail gets into his e-mail infrastructure.

The problem he's going to hit is that he wants *my* mail server to send mail to
'[email protected]' to get routed to the MX in San Fran where Fred is, and *my*
mail server to send mail '[email protected]' to get routed to the MX in Geneva
where Johann is, and avoid having a central MX that then does routing.

And basically, he's screwed, because the MX lookup is only based on the RHS
of the target address.  AT *best* he can deploy a @NN.example.com and have
different MX entries for US.example.com and FR.example.com and so on (but he
already said that's a suboptimal).
