All mail will be forwarded to one host. Run dpkg-reconfigure to reconfigure exim4 and set it up for smarthost.
I think he's talking about a mail *hub*, where Exim receives incoming mail and then passes it on to Exchange.
It depends a little on what version of Exchange he's running. It's more complex with Exchange 5.5 and earlier, because they don't verify recipients during the SMTP transaction -- to ensure a user is valid you have to use LDAP. With later versions you can use recipient verification in a more conventional way.
I haven't really done this since Exim 3 and Exchange 5.5, so I'm not sure I can be much help with the details. I seem to recall the Exim source distribution had some sample configuration files, one of which was a mail hub with Exchange as the destination. He might be best off asking on the Exim mailing list.
