DKIM Record Checker
Verify your DKIM (DomainKeys Identified Mail) configuration. DKIM adds a digital signature to your emails, proving they haven't been altered in transit.
What is DKIM?
DKIM (DomainKeys Identified Mail) is an email authentication method that allows the receiver to verify that an email was sent by the owner of the domain and wasn't modified during transit. It uses public-key cryptography to sign emails.
How DKIM Works
- Your email server signs outgoing emails with a private key
- The signature is added to the email headers
- Receiving servers look up your public key via DNS
- The signature is verified using the public key
Finding Your DKIM Selector
To find your DKIM selector, check the email headers of a sent message. Look for the "DKIM-Signature" header and find the "s=" value - that's your selector.
