 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.
