I am having trouble sending mail from coldfusion 8 through an exchange 2007 server. I have two exchange servers one on Server 2003 and one on Server 2008. I am in the process of removing the 2003 box but when I point coldfusion to the 2008 box outside mail (mail sent to external addresses) stops working. I get "invalid address" in the mail log. The send connector on Exchange 2007 appears to be universal to all hub transport servers the receive connectors are set-up the same on both boxes.
