Action for mail servers if a message fails DMARC. Start with 'None'.

Receive daily DMARC summary reports. Comma-separate multiple addresses.

Apply policy to this percentage of failing emails (0-100).

'Relaxed' is common.

'Relaxed' is common.

Specifies how forensic reports are generated if RUF is enabled.

Your Generated DMARC Record

Publish this TXT record in your DNS for the hostname:
_dmarc.yourdomain.com

Important Next Steps:

  • Start with p=none to monitor reports before enforcing quarantine or reject.
  • Regularly check your RUA reports to understand your email streams and identify legitimate senders.
  • Gradually increase the pct tag (e.g., 10% → 50% → 100%) when moving to stricter policies.
  • Incrementally update policy strictness (none → quarantine → reject) only once confident.

Demystifying DMARC

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol designed to protect your domain from unauthorized use, like spoofing and phishing.

Key DMARC Tags

v=DMARC1
Version. Mandatory.
p=policy
Policy (none, quarantine, reject). Mandatory.
rua=mailto:address
URIs for aggregate reports. Recommended.

FAQs

Start with p=none (monitoring mode) to analyze reports without impacting email delivery. Gradually move to stricter policies like p=quarantine or p=reject after careful analysis.

Regularly, especially initially. Daily or weekly checks are common during the setup phase to identify all legitimate sending sources and fix authentication issues.

Yes, if misconfigured or if a strict policy (quarantine/reject) is set before all legitimate sending sources are properly authenticated (SPF/DKIM aligned). Always start with p=none.

RUA (Aggregate): XML reports providing an overview of email traffic, authentication results, and IP sources. Essential for monitoring.

RUF (Forensic): Redacted copies of individual emails that failed DMARC. Can be high volume and contain sensitive data; use judiciously.
