MX Records (Mail Exchange Records) are a type of DNS (Domain Name System) record used to route emails sent to your domain. They tell the internet which mail servers are responsible for receiving email on behalf of your domain name (e.g., yourdomain.com).
How They Work:
When someone sends an email to info@yourdomain.com, the MX records for yourdomain.com are checked. These records direct the email to the correct mail server.
Each MX record has:
- Priority (a number): Lower numbers are higher priority.
- Mail server address (e.g., mail.yourdomain.com): Where email should be delivered.
Example:
Priority: 10
Mail Server: mail.yourdomain.com
This tells the internet:
“Send email for this domain to mail.yourdomain.com, and give it priority 10.”
Important Notes:
- You can have multiple MX records with different priorities for backup mail delivery.
- Correctly configured MX records are essential for email to work.
- If you’re using services like Gmail or Microsoft 365, you’ll need to point your MX records to their servers.
Without properly configured MX records, you won’t receive emails to your domain.
