Inspection Results
Understanding Priority Values
Lower priority numbers indicate higher preference. Email servers try to deliver to the lowest priority (primary) server first. If that fails, they fall back to servers with higher priority numbers (backup servers).
Understanding MX Records and Their Importance
What are MX Records?
MX (Mail Exchange) records are DNS entries that specify the mail servers responsible for receiving email on behalf of a domain. They contain information about the priority and target mail servers, guiding the routing of emails to the correct destination. Without properly configured MX records, emails sent to your domain won't be delivered.
Why are MX Records Important?
Email Delivery
MX records are essential for directing email traffic to the correct mail servers, ensuring that your emails are delivered to the intended recipients without delays or bounces.
Redundancy and Reliability
By specifying multiple MX records with different priorities, you can set up backup mail servers, enhancing the reliability and availability of your email service even during outages.
Troubleshooting
Inspecting MX records can help diagnose issues with email delivery, such as misconfigurations, DNS propagation delays, or server problems, allowing you to resolve them promptly.
How MX Record Priority Works
Primary Server (Lowest Priority Number)
The server with the lowest priority number is tried first. This is typically your main mail server that handles all incoming email.
Secondary Server (Backup)
If the primary server is unavailable, sending servers will try the next lowest priority. Multiple backups ensure email delivery during outages.
Tertiary Servers (Additional Backups)
Additional servers with higher priority numbers serve as further fallbacks, providing maximum redundancy for mission-critical email systems.
