I'm moving to Google Apps and have setup dual-delivery. Everything is fine, but for mail sent internally (from sally@mydomain.com to john@mydomain.com), Exchange is not using the send connectors I have pointing to Google's servers.
I believe my question is similar to this question:
How to force internal email through an smtp connector in exchange 2007
Again, if a user is connected to the Exchange server and tries to send to george@outsidedomain.com it works just fine, but I cannot seem to force *@mydomain.com to route correctly.
This should be a fairly simple, but according to this:

(can't post two links due to spam prevention)
It does not seem possible. Any ideas?

I think the only way would be to create an alias domain called google.mydomain.com, register that domain as an alias with Google Apps, and then create Active Directory Contacts for each user:
John Forwarder email address: john@google.mydomain.com
Sally Forwarder email address: sally@google.mydomain.com
Once that's done, open up the Exchange General properties (I think, it's one of those tabs) under Active Directory Users and Computers for each user and set the mail to forward to the corresponding "John Forwarder" contact (make sure the "send to both email accounts" checkbox is enabled or the like, again, I'm not on a server right now).
That's the gist of it, I can fill in specifics later on today if need be.
