 MX resolution
You are trying to resolve the MX for zimbra.foostuff.com instead of foostuff.com.
zimbra.foostuff.com is the FQDN of the mail server and foostuff.com is the domain. MX records are setup and resolved for domains.
The Zimbra install tries to set the domain to the FQDN of the server instead of the domain itself. During the install you must change the domain name that Zimbra wants to use to the domain name and not the FQDN of the host. |
