Notes to take in mind if you are going to manage email accounts in your server
De GIGAS DOCS
If you are going to use email services in your server you must take in mind these points:
- The chosen hostname to create the machine must be a valid domain hosted in the server.
- If you are going to use Plesk or Cpanel as control panel, you must set the hostname to a valid domain hosted in the server during the initial config wizard.
