Exchange 2010, Exchange 2003 Mail Flow issue

I'll look at that.

So after tracking these messages that our 2003 server is bouncing back if sent from the a blackberry on exch2010 in ESM...I get this....



*red box is just removing my email address

It says it is delivering the message locally (i never get it) and then immediately it generates the NDR which I get on the blackberry.

What the heck? I even went as far as to add the ip of the new bes and exchange 2010 servers to the 2003 server's smtp relay restrictions thinking that would help...still nothing. I have no idea wtf is going on at this point.
