Mx Record Checker
This MX Record Checker verifies mail exchange servers and email routing configuration.
About This Tool
The MX Record Checker retrieves mail exchange (MX) records assigned to a domain and displays mail server priority values.
MX records control how incoming email is routed. Incorrect configuration can result in email delivery failures.
Use this tool to verify email routing setup, troubleshoot mail server issues, and confirm correct priority configuration.
Frequently Asked Questions
What is an MX record?
An MX (Mail Exchange) record is a DNS record that specifies which mail servers are responsible for receiving email messages for a domain. It directs incoming emails to the correct mail server.
What does MX priority mean?
Each MX record has a priority number.
Lower numbers indicate higher priority.
For example:
Priority 10 → Primary mail server
Priority 20 → Backup mail server
If the primary server is unavailable, email will be routed to the next lowest priority server.
Why am I not receiving emails even though MX records exist?
Common reasons include:
Incorrect mail server hostname
Firewall blocking mail ports
DNS propagation delay
Wrong MX priority configuration
Email service misconfiguration
Even if MX records are present, email delivery can fail due to server-level issues.
How long does it take for MX record changes to update?
MX record changes usually propagate within a few minutes to 48 hours, depending on the DNS TTL (Time To Live) value and global DNS cache behavior.
Can I check MX records without accessing my hosting account?
Yes. MX records are public DNS data. This tool retrieves live DNS information without requiring login access to your hosting provider or domain registrar.
Do MX records affect outgoing email?
No. MX records only control incoming email routing.
Outgoing emails are controlled by SMTP configuration on your mail server or email provider.
