  • Facet 1: Understanding MX Record Priority

    MX records can have multiple entries, each with a unique priority value. The priority value determines the preference for selecting a mail server. A lower priority value indicates a higher preference. When an email client connects to a domain to deliver an email, it will attempt to connect to the mail server with the lowest priority value first. If that mail server is unavailable or experiencing issues, the email client will move on to the next mail server with the next lowest priority value and so on.

  • Facet 2: Configuring MX Record Priority

    When configuring MX records, it is important to assign appropriate priority values to ensure optimal email delivery. Typically, the primary mail server is assigned the lowest priority value (e.g., 0 or 10), followed by backup mail servers with incrementally higher priority values (e.g., 10, 20, 30). This configuration ensures that emails are delivered to the primary mail server as the first choice, and if the primary mail server is unavailable, the backup mail servers are used in order of their priority.

  • Facet 3: Troubleshooting Email Delivery Problems

    Checking MX record priorities can be helpful in troubleshooting email delivery problems. If emails are not being delivered or are experiencing delays, it is important to verify that the MX records are configured correctly and that the priority values are assigned appropriately. Incorrect MX record priorities can cause emails to be routed to the wrong mail server or to be dropped altogether.
