DomainKeys Identified Mail (DKIM) is an email authentication method designed to detect email spoofing, ensuring messages are not altered in transit. It allows the receiving mail server to verify that a message was sent from the authorized domain and that the message content has not been tampered with. Configuration of DKIM involves generating a public and private key pair and publishing the public key in the Domain Name System (DNS) record.
Implementing DKIM enhances email deliverability and strengthens sender reputation, minimizing the risk of emails being marked as spam. Historically, email systems lacked robust authentication mechanisms, making them susceptible to phishing and spoofing attacks. DKIM provides a cryptographic signature, adding a layer of security and trustworthiness to email communication. By validating the authenticity of email messages, it helps protect recipients from malicious activities and builds trust between sender and receiver.
