MX Record Lookup

Look up MX, SPF, DMARC and DKIM records for any domain to verify email configuration.

Domain Name

MX Record Lookup

MX (Mail Exchange) records are DNS records that specify which mail servers are responsible for accepting email on behalf of a domain. Lower priority numbers indicate higher preference.

Email Authentication Records

SPF (Sender Policy Framework): A TXT record that defines which mail servers are authorized to send email for your domain. Prevents email spoofing.
DMARC (Domain-based Message Authentication): Builds on SPF and DKIM to tell receiving servers what to do with emails that fail authentication checks.
DKIM (DomainKeys Identified Mail): Adds a digital signature to outgoing emails so receiving servers can verify the message was not tampered with.

MX Priority Explained

When a domain has multiple MX records, the priority value determines which server is tried first. A lower number means higher priority. Servers with equal priority are used in round-robin fashion.
