You could distribute the table using whatever technology you like, e.g. LDAP. Google for Schlumberger Exim LDAP for a complicated example, though it can be done much more simply.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).
He needs something like the distributed clustering of qmail-ldap. Any mail- cluster member can accept messages for all others and does direct internal redistribution without going through HQ. No country specific subdomains needed. Everything has [email protected] -- Andre
