How to Change the Mail Exchanger(MX) Entry
Posted by Allura on 08 02 2019.
The most important function of a ‘Mail Exchanger Entry’ is to determine which particular server receives mail for a given domain name.
When one edits an entry using the ‘Edit MX Entry’ interface it allows one to configure the entry for each destination mail server.
One can reach the ‘Edit Mail Exchanger (MX) Entry’ interface from the DNS Functions interface, which in turn can be accessed from the WHM Home interface.
The Process of Changing a Mail Exchanger Entry
The following steps need to be followed by a user who is attempting to change or edit an MX Entry:
- To begin, select the name of the the particular domain from which to configure the mail exchanger entry. This can be done by accessing the ‘choose a domain to edit’ menu.
- Having selected a domain, one must choose the Edit option. Once that is done a new interface can be accessed.
- Therein one can select the given Email Routing setting that one wishes to set and use.
- Once all of the aforementioned steps have been completed one can manually change the settings for each mail exchanger entry from the section specifically called MX Entries Section.
- Finally, one simply has to click Save to conclude the process.
This, the process of changing MX Entries is simple, has a number of defined steps and is easy to execute.
A Few Details
Each MX entry can be configured in relation to certain specificities or settings. These are the following:
- TTL – This specifically refers to the ‘time to live’ and indicates the duration for which a given record is stored in memory before it automatically refreshes. This integer value is displayed in seconds and usually auto-reverts to 14400.
- Priority Value – This refers to another integer value which is set depending on the priority order of the particular mail server when viewed in correlation to other Mail Exchanger Entries. However, the lower the server’s assigned ‘Priority Value’, the higher is its priority. Hence, servers with the lowest priority value act as the primary mail servers while those with lower priority values act only as secondary mail servers. In the event that multiple servers have the same value, mail is distributed simultaneously and at random to those servers by the systemic process.
- MX Destination – This simply refers to the name if the given mail server and may be edited as well.
Finally, it is useful to keep in mind that one can also add or delete New MX Entry Text Boxes at will by clicking the Add Another MX Entry Field option.
