    It's not the domain that is a relay it's your server that is a relay, you've most likely changed the configuration to allow the server to be an opon relay. A default configuration of Zimbra is not an open relay as you've already demonstrated by configuring a new ZCS server which you say is not a relay. Search the forums for details of what causes and open relay and what you can do to fix it.
