How DMARC Works ?

Section titled “How DMARC Works ?”

DMARC removes guesswork from the receiver’s handling of emails from non-authoritative email servers, reducing the user’s exposure to potentially fraudulent and harmful messages. A DMARC policy allows a sender to indicate that their emails are protected by Sender Policy Framework (SPF) and/or Domain Keys Identified Message (DKIM), both of which are industry-recognized email authentication techniques. DMARC also provides instructions on how the receiver should handle emails that fail to pass SPF or DKIM authentication. Options include sending the email to quarantine or rejecting it entirely. Lastly, DMARC provides the receiver with an email address to provide feedback to the sender. Potential feedback can include that the sender’s email was rejected/quarantined by the receiver or that a threat actor is attempting to imitate the sender’s domain.

Authentication Process

Section titled “Authentication Process”
  1. SPF Verification
    • Validates sending server’s IP address
    • Checks against authorized IP list
  2. DKIM Signature Validation
    • Cryptographically signs emails
    • Ensures message integrity
    • Prevents email tampering
  3. DMARC Policy Enforcement
    • Define handling for failed authentication
    • Configure policy modes:
      • Monitoring
      • Quarantine
      • Reject
Section titled “Recommended Deployment Strategy”

Organizations that adopt DMARC do so in a staged approach, with feedback loops between IT departments and their staff. Because DMARC can block third parties delivering mail on the purported sender’s behalf, some intended messages may be flagged as illegitimate in some cases. Below are a few steps organizations can take to ease into DMARC over time.

  1. Monitoring Mode
    • Observe email authentication
    • Collect infrastructure insights
  2. Quarantine Mode
    • Isolate suspicious emails
    • Refine authentication rules
  3. Reject Mode

    • Block unauthenticated emails

    • Maximize email security
