Let's dive into it!


DNS (Domain Name System) settings are crucial for verifying sender authenticity, improving email deliverability, and protecting against phishing. The key DNS records involved in email authentication include SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance).


SPF and Its Importance

SPF records help mail servers verify that the incoming emails from a domain are sent from authorized mail servers. It prevents email spoofing and ensures that your emails are trusted by the recipient's email servers.


DKIM: The Email Signature

DKIM adds a digital signature to the email's headers. This signature is verified against a public key in the domain's DNS records. It ensures the email has not been tampered with during transit and adds a layer of trust.


DMARC: Combining SPF and DKIM

DMARC uses SPF and DKIM to provide a framework for email authentication, policy enforcement, and reporting. It allows domain owners to specify how email receiving servers should handle unauthenticated emails, adding an extra layer of security and trust.
