Exchange email routing

Hello,
We are looking to route all mail to one particular domain through a vpn tunnel and not out to the internet with all other mail. Basically we have two sites (two separate domains) but we are connected by a vpn tunnel. We are both running exchange 2010 and would like email that is sent to each others site to go over the vpn tunnel. What is the best way to achieve our results?  Send Connector? Redirect via spam filter or firewall? Any help is greatly appreciated.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Create a new send connector with the recipient domain in the address space and making sure the cost is lower than the default send connector with all domains name space.

So it will always check the send connector with the lowest cost 1st. Thus when internal users send an email to xxx@yyy.com users, it will hit the newly created send connector which is route the mail to through the VPN  tunnel.
