MX Record Checker
Enter a domain to look up its MX (mail exchange) records and their priority.
About this tool
A lower priority number is tried first. This uses real DNS resolution via Node's built-in resolver — no third-party API.
Frequently Asked Questions
- What does an MX record do?
- It specifies which mail servers accept email for a domain, and in what priority order.
- What does a lower priority number mean?
- It's tried first — the lowest-numbered MX record is the primary mail server.
- What if no MX records are found?
- The domain likely doesn't accept email directly, or mail is handled by a different configuration entirely.
