MX Validator

Ensure Reliable Email Delivery with Accurate Mail Server Configuration

Validate your domain's MX (Mail Exchange) records with our MX Record Validator. This tool ensures your mail server settings are properly configured, accessible, and optimized for reliable email delivery. Prevent missed emails, improve deliverability, and secure your domain by maintaining accurate MX records.

What are MX Records?

MX (Mail Exchange) records are DNS (Domain Name System) records that specify the mail servers responsible for receiving emails on behalf of your domain. They direct email traffic to the correct server and determine the priority of each mail server in case multiple servers are listed.

Why are MX Records Important?

Direct Email Traffic: MX records ensure that emails sent to your domain are routed to the correct mail servers.
Reliable Email Delivery: Properly configured MX records prevent email delivery failures and minimize downtime.
Load Balancing and Redundancy: By listing multiple MX records with varying priorities, you can distribute email traffic and provide failover in case a server is unavailable.

How Do MX Records Work?

DNS Query: When someone sends an email to your domain, the sender’s mail server queries your DNS for the MX records.
Server Priority: The MX records list mail servers along with their priority (lower values indicate higher priority). The sending server attempts to deliver the email to the server with the highest priority first.
Backup Servers: If the primary server is unavailable, the sending server retries delivery with the next highest-priority mail server.

Common MX Record Issues

Incorrect or Missing Records: Emails may fail to reach your domain if MX records are not set up correctly or are missing entirely.
Misconfigured Priorities: Improper priority values can lead to inefficient email routing or delivery issues during server failover.
Non-Existent or Unreachable Mail Servers: MX records pointing to invalid or inaccessible mail servers result in bounced emails.

Best Practices for MX Records

Use Fully Qualified Domain Names (FQDNs): MX records should always point to FQDNs, not IP addresses.
Test Regularly: Validate your MX records to ensure they are pointing to operational and accessible mail servers.
Set Backup Servers: Configure secondary servers with appropriate priority values for redundancy and failover.
Monitor DNS Changes: Keep track of any changes to your DNS records to prevent accidental misconfigurations.
