I have built a new Exchange 2003 server in a new domain, replacing an Exchange 5.5 server in a different domain.
I need this Exchange 2003 server to route incoming mail, using the old 5.5 address, for
a handfull of users.
How do i tell the Exchange 2003 server that it should route the new email address for all users
and also route the old email for only a few users ?
(I do not want to generate the old email address for new users on the Exch 2003 server
that were never on the old 5.5)
