Email-authentication protocols are a set of standards and mechanisms designed to verify the legitimacy of email sources and prevent email spoofing. These protocols help ensure that emails sent from a domain are authorized by the domain owner, thereby reducing spam, phishing attacks, and impersonation. Common protocols include SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance).
