DomainKeys Identified Mail (DKIM)

DomainKeys Identified Mail (DKIM) is an email authentication method that helps verify whether an email genuinely comes from the sender it claims to be from. When an email is sent, the sender’s mail server adds a unique digital signature to the message using a private key. The recipient’s email system can then check this signature using the sender’s public key (found in DNS records) to confirm the email hasn’t been altered and really originates from that domain. This process helps prevent email fraud and ensures message integrity, boosting trustworthiness and reducing spam.
