Email Authentication Definition: Email authentication is the process of verifying that an email message comes from a legitimate sender by validating the message's sender and ensuring its integrity through mechanisms like SPF, DKIM, and DMARC.
Email authentication is a set of techniques used to verify the identity of the sender and ensure the integrity of email messages. It helps in preventing email spoofing, phishing, and other malicious activities by using methods like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance). These techniques authenticate the sender's domain, digitally sign email messages, and provide policies for handling unauthorized emails, respectively.
