Hi all, Since I've installed my new Exchange 2007 Server, My Sharepoint Server is unable to delivering email external addresses. It is working with internet domain addresses, but when it goes to external, it failed... I know the problem is arround my send connector, but why? What I Have to do to make it work? Thanks!
