What are MX Records?

MX (Mail Exchange) records are DNS records that specify the mail servers responsible for accepting email messages on behalf of a domain. They are essential for email delivery and must be properly configured for your domain to receive emails.

Key Components:

Priority: Lower numbers indicate higher priority mail servers
Mail Server: The hostname of the mail server (must be a fully qualified domain name)
TTL: Time To Live - how long the record should be cached

How MX Records Work:

When someone sends an email to your domain, their mail server looks up your MX records
The sending server tries to deliver to the highest priority (lowest number) server first
If the primary server is unavailable, it tries the next priority server
This process continues until the email is delivered or all servers fail
