FAQ
What is an MX Record?
An MX (Mail Exchange) record is a type of DNS record that specifies which mail servers are responsible for receiving email messages on behalf of a domain name.
What does Priority mean in MX records?
Priority numbers indicate the preferred order of mail delivery. Lower numbers have higher priority. For example, a server with priority 10 will be tried before a server with priority 20.
Why is there a cooldown period?
The cooldown period helps prevent excessive DNS queries and ensures fair usage of the service. You can view your previous lookups in the history section while waiting.
How long are results stored in history?
The tool stores your 10 most recent MX record lookups locally in your browser. This history persists until you clear your browser data.
Why do I need to check MX records?
MX record checks are useful for:
- - Verifying email server configuration
- - Troubleshooting email delivery issues
- - Setting up new email services
- - Confirming email server changes have propagated
What if no MX records are found?
If no MX records are found, it might mean the domain isn't configured for email or there might be an issue with the domain's DNS configuration. Consider checking A records as some systems fall back to these for mail delivery.
