This configuration is necessary for Zimbra's reverse proxy and issues may happen when missing or invalid configuration in your domain - please make sure that the following Zimbra configuration keys are valid and set for that domain: zimbraPublicServiceHostname, zimbraPublicServicePort and zimbraPublicServiceProtocol

That can be verified with the output of:

for dom in $(zmprov gad); do zmprov gd $dom zimbraPublicServiceProtocol zimbraPublicServiceHostname zimbraPublicServicePort; done

Additionally, the Domain configuration can be accessed on GUI Admin panel through the menus Configure > Domains > Your Domain;

And in CLI running: zmprov md DOMAIN.TDL zimbraPublicServiceProtocol PROTOCOL zimbraPublicServiceHostname HOSTNAME zimbraPublicServicePort PORT,

Please remember to substitute the uppercase values according to your needs, example:

zmprov md example.com zimbraPublicServiceProtocol https zimbraPublicServiceHostname mail.example.com zimbraPublicServicePort 443

Then if any changes were made, please regenerate the reverse proxy scripts with /opt/zimbra/libexec/zmproxyconfgen and finally restart the reverse proxy with zmproxyctl restart command.

Then clear server cache with zmprov fc all && zmprov fc zimlet as a good practice.


Hope this was helpful, please let me know if you require any further assistance.

Every time I reboot or restart the mail server I see this message:
The following domains are missing:
Domain 'domain.ca' is missing host name.

Is there something to be done to resolve it since the domain is still existing.

Thank you
