I currently have my Zimbra E-mail server providing e-mail for "mydomain.com" and "mail.mydomain.com". I have just registered a new domain, one of those .us types, and my ISP is taking care of the DNS records. I need to add "mynewdomain.us" and "mail.mynewdaomain.us" to my existing mail server without fouling up my current config allowing for some time for everyone to notify the domain name changes. Do I just "add" the domains using the admin console GUI???. some help please.:
