I'm new to Zimbra and have searched all config and forums - how do I set a default value for all domains (current and new)? Especially, I would like to define zimbraPublicServiceHostname to a specific value (I'm running Zimbra behind a ZXTM trafficmanager). I can define the value with zmprov md example.com etc, but I would like to make it a default for all domains.

best regards,
