Edit MX Entry
An MX entry is a Mail Exchange entry, these help to determine which server receives mail for a domain name. This interface allows you to configure the entry for each destination mail server.
How to edit MX entries
In order to edit your servers MX entries you will need to do the following;
From the Choose a Domain to Edit menu you will need to select the name of the domain for which you wish to configure the MX entries and click "Edit".
A new interface will then appear. Select the "Email Routing" setting that you wish to use.
Enter your desired settings for each MX entry in the MX Entries section.
Finally click "Save".
You can select from any of the following "Email Routing" settings in order to change the configuration of your mail exchangers.
Automatically Detect Configuration - If you select this setting, it will allow the system to choose the most appropriate Email Routing setting, which is based on a query of the MX record. The system will query the MX record and uses the following criteria to determine the Email Routing setting;
If the lowest priority mail exchanger points to an IP address on this server, the system selects the Local Mail Exchanger setting.
The system will not be able to perform automatic detection for this setting if the MX entry fails to resolve (for example, if you mistype a domain name or enter one that does not exist). If the MX entry does not resolve and the Email Routing setting is Automatically Detect Configuration, the system generates a warning and will default to the last known Email Routing setting.
Local Mail Exchanger - Select this setting to cause the server to always accept mail for the domain.
You can configure the following values for each MX entry;
TTL - This integer value specifies the time to live (TTL). - TTL indicates how long a particular record remains in memory, in seconds, before it refreshes. This value defaults to 14400.
The servers with the lowest Priority values act as the primary mail servers.
MX Destination - Enter the name of the mail server (for example, mail.example.com).
Adding and Deleting MX Entries
To add a new MX entry simply click "Add Another MX Entry Field". A new textbox will apear where you can enter the new entry.
To delete an entry click on "Delete" next to the MX entry you wish to remove.
