Hi
I am new to cwp panel I tried to find through the forum but did not get it.
I get this error : (ERROR: You don't have a valid hostname set!)
in: postfix_manager and in change_hostname
For now I am trying to use this centos 7 server only internally for website testing purpose. Then it will be for production but my website is on production on another server.
I have read to set an A record, a subdomain and more, well I am a little lost
