MX record lookup
Enter a domain to see which mail servers handle its email — with priorities, resolved IP addresses and TTLs, straight from public DNS.
MX records for
| Priority | Mail server | IP address | TTL |
|---|---|---|---|
This domain does not accept email.
It publishes a null MX record (RFC 7505), explicitly declaring that no mail server handles its email.
No MX records found.
Per RFC 5321, mail would fall back to the domain's A/AAAA record:
This domain has no mail servers configured and can't receive email.
What is an MX record?
An MX (Mail Exchange) record is a DNS entry that tells other mail servers where to deliver email for a domain. Each record points to a hostname and carries a priority — lower numbers are tried first, so you can run a primary server with backups behind it. If two records share a priority, mail is balanced between them.
Misconfigured MX records are a common cause of bouncing or undelivered email. Use this tool to confirm a domain's mail servers resolve to the IPs you expect.
