DKIM Lookup

Looks up DKIM TXT and CNAME records for a given domain and selector by querying <selector>._domainkey.<domain>. DKIM (DomainKeys Identified Mail) lets receiving servers verify that email was signed by a key the domain owner controls. Use this to confirm your signing key is published and reachable.

      Understanding DKIM

      What is a DKIM selector?

      A DKIM selector identifies the DNS name containing a sender's public signing key. Find the selector in your email provider's configuration or in the s= tag of a message's DKIM-Signature header. A published key alone does not confirm that outgoing messages are signed correctly or aligned for DMARC.
