MX Record (mail exchanger record) is a DNS record that describes the mail server which is responsible for handling email messages for a domain name. These are important for email delivery. The MX Record Checker lets you check the MX record of your email domain.
Shown below is an example of MX record 10 mail.abcxyz.com
Here, ‘10’ is the priority. The lower the number, the higher is the priority!
For example, when you enter www.abcxyz.com in your browser, the DNS looks up that name to determine the IP address of the server to which it connects. The domain name is abcxyz.com.
The ‘mail.abcxyz.com’ is the mail server to which the priority connects. This varies with which company is hosting your email.
Backup MX system functions as a fail-safe mail server solution in case of failure of your existing email service.
There are always one or more MX records in the DNS server for every email domain. Every MX record on the DNS server assigns a priority to the mail servers. It determines the order in which the mail servers will be used. The mail servers are chosen based on the priority value. The server with the lowest priority is used first.
Example - If one mail server in your MX record has been assigned a priority value of 10 and another has been assigned a priority value of 20, mails will be routed to the primary server. However, if something goes wrong with the mail server that has the priority value of 10, the server with a priority value of 20 will be chosen for the domain. This server is the Backup MX server.
Go to your domain host account and then add your MX record in the record category “MX”. Your domain host account is the domain registrar from where you purchased your domain.
For checking your email domain’s MX record, use this online MX Record Checker Tool. Just enter your email domain in the input field and your MX record will be displayed in the result.
