OK, have Exchange 2007 and here is the scenario. We have two hub transports and the primary mail server at one location. A DR site with one Hub transport and one DR mail server. We are setting up a DR scenario using Wansync over at another site which uses DNS redirection. As AD and Exchange sees it this DR site is truely another site in AD and causes it to give a warning about Source Servers in different sites were detected for connector XYZ. The connector is our outbound internet mail connector. Since in a DR scenario the server would then switch to the other site and I figured users would start connecting and sending over the other Hub Transport at the DR site I added that as a server that could send over the connector. So should I create a second internet send connector and just add the DR site hub transport or is this warning something that can really be ignored? Thanks!!
