Hi there. I am building a pilot Zimbra server for a simple relay server. I need all outgoing mail to go to Postini. This works beautifully. My issue is with local delivery. Because I have a current live environment I can't use local delivery at this point therefore I can deliver to users on my domain. I have not had any issues delivering off domain (yahoo.com, gmail.com). How can I turn off local delivery?

thanks.
