Okay, that's easy; you put each branch domain in rcpthosts, and give it
an appropriate smtproutes entry.

Alright. company.com becomes a virtual domain on the central server.
You can then forward mail from various users in it to the various branch
domains using .qmail files, or perhaps with the fastforward package.
You'd do this with something like this in virtualdomains:
company.com:alias-company
and ~alias/.qmail-company-default containing:
|fastforward

This becomes difficult with stock qmail -- you end up having to
distribute some form of mapping from users to branch domains. It's
possible, again with fastforward or .qmail files, but it's an
administrative hassle.
LDAP comes to mind as a solution here -- either an LDAP PAM module an
unpatched qmail, or qmail-ldap. I'm afraid I can't offer much advice on
qmail-ldap.
