What is DKIM Record?

A technique frequently used in phishing or spam emails, DKIM (DomainKeys Identified Mail) is an email authentication system meant to identify counterfeit sender addresses in emails. It enables an email's recipient to confirm that the message was not altered while in route and that it was delivered from the domain it purports to be from.

How DKIM Record Works?

• DKIM uses a private key to sign emails that are sent out digitally.
• The signature is specific to the content of the email and is appended to the email headers.
• For verification purposes, the domain’s public key is kept in its DNS records.
• To validate the signature, the recipient's mail server retrieves the public key from DNS.
• The email is verified if the signature matches; if not, it is regarded as suspicious.
