A Mail Exchanger (MX) record specifies a mail server for the domain other than the SMTP server provided by Parallels Pro Control Panel. You can designate more than one external mail server for the domain.
You can add the record only if your service provider has enabled the capability in the DNS policy file. If not enabled, the control panel displays a message stating that the policy settings do not allow you to add the zone record. Contact your service provider if you want the settings changed.
Note: Add a Host (A) record for the host running your mail server before you create the MX record pointing to it.
To add an MX record:
Note: The lower the number in this field, the higher the priority. For example, if you have two mail servers, you could assign a delivery priority of 3 to one server and 4 to the other. Mail would be delivered to the precedent 3 mail server first. If delivery fails there, it would be delivered to the precedent 4 mail server.
