2. What is the Role of Email Authentication Protocols?
Email authentication protocols like DKIM (DomainKeys Identified Mail), SPF (Sender Policy Framework), and DMARC (Domain-based Message Authentication, Reporting & Conformance) play a vital role in verifying the legitimacy of your emails. These protocols help protect your domain from being used in phishing and spam attacks. DKIM allows the receiver to check that an email claiming to come from a specific domain was indeed authorized by the owner of that domain. SPF specifies which mail servers are permitted to send emails on behalf of your domain. DMARC builds on DKIM and SPF to provide a mechanism to report and take action on any unauthorized use of your domain.
