It's also impractical to deliver copies of every message to each of the
various offices, leaving thousands and thousands of unread messages for
the employees that don't work in each office.
This is where directory technologies like LDAP come into play, when you
have large user bases. I think this has strayed pretty far from the
question that was asked, though, which seemed to me to be a 'mail
gateway' attached to the internet at the company HQ that would route to
~3 internal mail servers, delivering the correct accounts to each one.
Wasn't that the original question?
Where am I, and what am I doing in this handbasket?
