DKIM Validator

Validate your domain's DKIM (DomainKeys Identified Mail) record for email authentication

What is DKIM?

DKIM (DomainKeys Identified Mail) is an email authentication method that allows the receiver to verify that an email was actually sent by the domain it claims to be from, and that the message wasn't altered during transit.

DKIM uses cryptographic signatures. When you send an email, your mail server signs it with a private key. The receiving server then validates the signature using the public key published in your DNS records.

DKIM Components:

  • Selector: Allows multiple DKIM keys per domain
  • Public Key: Published in DNS for verification
  • Private Key: Used by mail server to sign messages
  • Signature: Added to email headers
