Currently running Exchange 2007 using a base domain with several sub domains. All outbound mail is currently set to go out to the Internet via an internal smart host (Websense Email Security) configured in a single send connector. For testing purposes, I'd like to have one of the sub domains bypass this send connector and go out to a hosted provider (also Websense). Any thoughts on how to set this up so that Exchange routes the messages differently based on the internal sender's address, i.e. email@example.com?
