I'd like to configure an Exchange 2010 SP1 receive connector for anonymous mail, have it resolve to the GAL, but NOT allow it to relay outside my organization. This connector is only to be used by internal applications for internal e-mail deliver only. So far, I have been able to find out how achieve this but the connector would also allow mail relay.
Does anybody know how to achieve this?
