He *might* be able to sell the various branch offices on a solution that uses LDAP or similar (Andre Oppermann suggested qmail-ldap), where each branch manages its section of the LDAP tree, and the only centralized part the offices would have to trust HQ to do is possibly run a robust redirector to the various LDAP servers. Sorry Andrew - but that's probably the "best suboptimal" that you'll be able to actually deploy within the context of SMTP....
