What is an MX record and why is it important?

An MX (Mail Exchange) record is a DNS entry that tells email systems where to send emails for a specific domain. It's critical because without proper MX records configured, emails cannot be delivered to your domain. MX Checker helps you verify these records are correctly set up and pointing to the right mail servers.

Why are my emails not being delivered?

Email delivery issues often stem from misconfigured MX records. Use MX Checker to verify your domain's MX records are correctly configured and that the mail servers listed are actually running. Check that the priority values are appropriate and that your mail server is responding to connection attempts.

How many MX records should a domain have?

Most domains should have at least 2 MX records for redundancy and failover capability. This ensures that if the primary mail server is down, emails can still be delivered to a secondary server. However, you can have more than 2 records depending on your email infrastructure needs.

What does the priority number in MX records mean?

The priority number (also called preference value) determines the order in which mail servers are attempted. Lower numbers have higher priority, so a mail server with priority 10 will be tried before one with priority 20. If the first server is unavailable, the system automatically tries the next one in the list.

Can I use MX Checker to verify other domains?

Yes, MX Checker works with any domain. You can verify MX records for your own domains, client domains, or any public domain on the internet. This is useful for troubleshooting email issues, validating third-party services, or auditing email infrastructure across multiple domains.
