MX Record

  • What is MX Record? MX Record What does it do and how does MX record?
  • MX Mail (Mail Exchanger) is a type of DNS record that is associated with the domain name of the e-mail address to which the e-mail account of the recipient of the e-mail address belongs. While these types of DNS records are controlled by the Hosting company for Hosting users, the server-hosting Webmasters themselves can configure the MX records themselves.


  • Thanks to the MX Record, mail can be successfully sent to the email addresses hosted on our server. MX records do not have to be one, so MX records can be configured by entering MX records in multiple numbers. If more than one MX record is sent, if an email is sent from one of your site’s mail accounts, the first MX record for that domain is checked first, if the user’s account is not found in the first MX record, the other MX records are checked and the email is forwarded correctly via the corresponding MX record.


  • Having more than one MX record helps to deliver email in a lossless manner, providing load balancing if the server is in trouble. If you have a large number of MX records, you also need to prioritize MX records. Thus, it is possible to determine which MX records to use first.


  • Mail servers send and receive e-mails over the internet. These records, called MX, Mail Exchanger, confirm that the mail arrives and help to transfer the e-mail to the associated mail account in your domain. By default, many system automatically configure MX records (MX Records), and webmasters do not need to edit these records from scratch. MX records are rarely updated records when multiple websites are hosted on the network and special circumstances arise.


  • Under normal circumstances, you have more than one MX record associated with your domain name. If your service is unavailable due to these MX records, it will try to deliver the email to the account via the other MX record. Each MX record has priority order and number. When an e-mail arrives, the first attempt is made to reach the one with the highest priority. Then, other records with lower priority sequence are accessed sequentially.






  • For example; The MX0 record is associated with the address “mail.example.com”. In that case, the MX record to be tested first will be MX0. If we have more MX records, such as MX10, MX20, and MX30 associated with my domain step, these MX records will be MX records with lower priority and will be tried later.


  • Thanks to the MX records and the MX record priority system, when the default mail server is offline, other MX records can be used to deliver emails to the correct address without loss. Thus, if the server is unreachable, users will not experience e-mail loss.


  • How to Record MX?
  • You can configure MX records from your domain name’s panel and from the panel of your hosting method. Often, standard users and webmasters do not need extra MX recording. Creation and configuration of MX records is usually done by professionals. If you still think you might have accidentally edited your MX record, you can see the example MX structure below;


  • A recording
  • Mx1.whatisthewik.com (Local IP)
  • Mx2.whatisthewik.com (Local IP)


  • MX Record
  • 10 mx1.whatisthewik.com
  • 20 mx2.whatisthewik.com
