Where does Imail live?  If it's in front of the firewall, configure your
firewall to only allow connections on port 25 to your Exchange server from
the IP of the Imail server.  It it's behind the firewall, configure the
firewall to only allow connections on port 25 to go to the Imail server.
Also, make sure the Imail server is the lowest MX for your domain.
