If you have the problem I ran into where Zimbra installation reports a clash on port 53 due to a pre-existing installation of the Bind/Named service, you will get a prompt stating something like “Port conflict detected: 53 (zimbra-dnscache)” with a prompt to hit ENTER to continue, you can just hit enter and let the installation/upgrade run out. Once everything is running, you will see that the Zimbra DnsCahe service is in a stopped state. To fix this error, all you have to do is:
zmcontrol status zmprov ms `zmhostname` -zimbraServiceEnabled dnscache zmprov ms `zmhostname` -zimbraServiceInstalled dnscache zmcontrol status
You will see that the service is removed from Zimbra’s Services.
