Technical Glossary

Understanding DMARC and email authentication terminology

DMARC is an email authentication protocol that builds upon SPF and DKIM to provide domain owners with the ability to protect their domain from unauthorized use, commonly known as email spoofing.

Key functions:

  • Specifies how receivers should handle emails that fail authentication
  • Provides reporting mechanisms for domain owners
  • Enables gradual deployment through policy settings (none, quarantine, reject)

SPF is an email authentication method that allows domain owners to specify which mail servers are authorized to send emails on behalf of their domain.

How it works:

  • Published as a TXT record in DNS
  • Lists authorized IP addresses and mail servers
  • Receiving servers check the sender's IP against the SPF record

Example SPF record:
v=spf1 include:_spf.google.com ~all

DKIM is an email authentication method that uses digital signatures to verify that an email message was not forged or altered during transit.

Key components:

  • Private Key: Used by the sending server to sign emails
  • Public Key: Published in DNS for receiving servers to verify signatures
  • DKIM-Signature Header: Added to each email with the digital signature

Benefits: Ensures message integrity and confirms the sending domain's authorization.

Disposition refers to the action taken by the receiving mail server based on DMARC policy evaluation.

Possible dispositions:

  • None: No action taken, email delivered normally
  • Quarantine: Email marked as spam or moved to junk folder
  • Reject: Email completely rejected and not delivered

Note: The actual disposition may differ from your DMARC policy based on the receiving server's configuration and other factors.

Alignment refers to whether the domain used in SPF/DKIM authentication matches the domain in the "From" header of the email.

Types of alignment:

  • SPF Alignment: Compares the Return-Path domain with the From domain
  • DKIM Alignment: Compares the DKIM signing domain with the From domain

Alignment modes:

  • Strict (s): Domains must match exactly
  • Relaxed (r): Organizational domains must match (subdomains allowed)

Aggregate reports provide statistical data about email authentication results for your domain over a specified period (usually daily).

Information included:

  • Volume of emails processed
  • SPF and DKIM authentication results
  • DMARC policy evaluation outcomes
  • Source IP addresses and organizations
  • Disposition applied to messages

Purpose: Help domain owners understand their email ecosystem and identify potential issues or unauthorized usage.
