Why MX Records Matter for Email Delivery

MX records are fundamental to email delivery. They tell sending mail servers where to deliver emails for your domain. Without properly configured MX records, your domain cannot receive emails, which affects both incoming and outgoing email functionality.

  • Enable email delivery by routing emails to the correct mail servers
  • Provide redundancy with multiple MX records for reliability
  • Ensure proper routing so emails reach the intended mailboxes
  • Troubleshoot delivery issues by verifying DNS configuration
  • Maintain email functionality for both sending and receiving

How MX Record Checking Works

Our MX records checker performs comprehensive DNS queries:

  1. DNS query: Queries your domain's DNS servers for MX records
  2. Record retrieval: Retrieves all MX records with their priority values
  3. Server validation: Verifies that the mail servers in MX records are reachable
  4. Priority analysis: Checks that priorities are properly configured
  5. Configuration review: Identifies any issues or misconfigurations in your MX setup

This comprehensive check ensures your domain is properly configured to receive emails and helps identify any DNS issues that could affect email delivery.
