Exch 2007 - Redirect incoming mail to 2 organizations

Hi there,

What would be the easiest way to redirect incoming mail to another Exchange
2007 server in another forest? The problem is we have 2 forests and 2
different Exchange organizations, without trust relationships. Is there a way
to forward email for the recipients in one forest when they are not found in
the forest which would be the first to receive all email?

For example, forest 1 has 95% of all users, but there is a pilot deployment
in another forest with the same e-mail domain name. The edge server in forest
1 delivers email to the hub transport server in forest 1. However, we would
like the edge transport server, or hub transport server in forest 1 to be
able to pass emails onto the hub transport in forest 2, if the user has their
mailbox there. Is this possible?

Setup the Accepted Domain as an Internal Relay domain.
Create a Send Connector for the domain, add the remote mail host(s) as
smarthosts.
