This signature, generated by the sending server using a private key, allows the recipient’s mail server to verify the email’s integrity and authenticity. It confirms that the email content hasn’t been altered during transit, strengthening the overall security posture.

• DKIM uses public-key cryptography to digitally sign the email header.
• The recipient’s mail server uses the corresponding public key to verify the signature.
• Strengths lie in verifying the email’s content and origin, providing more robust authentication than SPF.
• Weaknesses can include the need for careful setup and potential issues with signing large email bodies.

DMARC (Domain-based Message Authentication, Reporting & Conformance)

DMARC is a policy framework that combines SPF and DKIM, enabling a comprehensive approach to email authentication. It defines the actions to take when an email doesn’t pass SPF or DKIM checks, helping to reduce spam and phishing attempts.

• DMARC policies instruct email receiving servers on how to handle emails that fail SPF or DKIM checks.
• These policies can be set to reject, quarantine, or report emails that fail authentication checks.
• Strengths include a more stringent authentication approach, providing a centralized mechanism to enforce policies.
• Weaknesses may include the potential for complex setup and potential misconfigurations if not correctly implemented.
