I have would like to setup two exchange 2007 servers in the same org. One server will have test.com the other will have testpa.com. There is a wan link between the two servers also. My questions is. One server will be doing massive mail sending the other will not. Will they each use their own smtp connector or is there a way to make sure each uses there own path.thanksJerry

There is a "source server" tab in the send connector. just choose the correct source server for the given connector. You could also configure an edge transport server as a 3rd (and fourth) server for each of your networks.
