How to use this tool
Displays only MX records, including the mail exchanger and numeric priority. Lower priority numbers are preferred.
Enter the target, complete any relevant options and choose Check. Review the requested records, query outcomes and diagnostic findings. Copy Report saves the visible report.
Reading the results
No matching records and an unavailable query are different outcomes. TTLs are displayed in seconds; zero is a valid TTL. A completed request does not mean a domain passed its health checks. Only the submitted DNS owner and explicitly listed checks are inspected.
Frequently Asked Questions
Why does the MX lookup show no records?
The domain may not publish an MX record, the name may be incorrect, or the resolver may not have the new record yet. Confirm the domain and check the DNS zone.
Why is an old mail server still listed?
A recursive resolver can retain the previous MX answer until its TTL ends. Wait for that cache period, then query the domain again.
Does an MX record prove that email delivery works?
No. The result only confirms the published DNS route. The receiving server can still be unavailable, reject mail, or have a separate configuration problem.
Can I enter a mail server hostname instead of the main domain?
You can query any hostname, but MX records normally belong to the domain that receives email. Enter that mail domain to inspect its route.
Where is the MX priority value?
This result table displays the record type, owner, mail host, and TTL. It does not show the MX preference number, so use a mail configuration check when priority order must be reviewed.
Why are several MX targets returned?
Domains often publish multiple receiving hosts for redundancy. Every active MX answer can appear as a separate row.
