New MX Record

Mail Exchanger or MX records are part of the DNS information for a domain. An MX record has a preference. Preferences are an unsigned 16bit number and hence, range from 0 to 65535. MX records with a lower preference are preferred. MX records with equal preference are valid and are treated equally.

You may create several MX records with different-priority (for example, 10, 100, 200, etc.) mail exchangers. The reason for setting up multiple MX records is a reliable mail delivery. If the primary mail server is down, the mail message will be temporarily sent to another mail server designated by the MX record. If this mail server is not responding, the message will be sent to lower-priority mail exchanger.

Note that Mail server indicated as "Mail Exchanger" should be configured properly so that it will be able to receive mail addressed to the Users of the "Destination" domain.

Field Purpose

Field Name | Description
Destination | Destination domain (select from drop-down menu). This is the primary mail server. In the case if the primary mail server is down, the mail message will be temporarily sent to another mail server (Mail Exchanger) designated by the MX record.
Priority | The priority for the MX record. As there can be multiple MX records for a domain, there has to be a way to control which mailhost is the destination mailhost, and in what order the other mailhosts are used if the destination mailhost is unreachable. A lower preference number means higher priority. Type the digit within the range from 0 to 65535
Mail Exchanger | The name of the mail server which will either process or forward mail for the domain. You should only use canonical host names (not alias names) in this field.
