Question details
Users are experiencing email delivery rejections accompanied by a permanent error message related to the evaluation of the domain's DMARC policy.

- Email and DNS Management
- Device & OS
- not provided
- Scenario
- Sending emails after implementing a new anti-phishing policy or updating domain DNS records.
- Observed behavior
- Outgoing messages bounce back and are rejected with a 'Permanent error evaluating DMARC policy' notification.
Ensure you have administrative access to your domain's DNS hosting provider (e.g., Cloudflare, GoDaddy, or Microsoft 365 Admin Center) to check and modify TXT records.
Allow Propagation and Verify DMARC Configurations
DNS changes require time to propagate. Verify your syntax and alignment if the issue persists after the propagation period.
Whenever you update your anti-phishing policies or modify DNS records, global email servers take time to recognize the new settings. If the syntax is correct but the error still occurs, propagation might be the culprit.
Allow up to 48 hours for any recent DNS or anti-phishing policy changes to fully propagate across global networks.
Log into your domain registrar or DNS management portal and locate your domain's TXT records.
Check the DMARC TXT record (usually hosted at _dmarc.yourdomain.com) for spelling and syntax errors, ensuring it correctly starts with 'v=DMARC1'.
Verify that your SPF and DKIM records properly align with the sending domain specified in the email's 'From' header.
Request Details from Recipient's Email Provider
If your DMARC configuration is demonstrably correct and fully propagated, the recipient's email server may have internal security policy conflicts.

Frequently Asked Questions
Why am I suddenly getting a DMARC permanent error?
This usually occurs immediately after modifying your domain's DNS records, setting up new anti-phishing policies in your email admin center, or if there is a typographical error in the DMARC TXT record syntax.
How long does a DMARC policy take to update?
Any modifications to your DMARC, SPF, or DKIM DNS records can take up to 48 hours to fully propagate globally. During this time, you might experience temporary evaluation errors.
What does DMARC alignment mean?
Alignment means that the domain in the visible 'From' header of your email matches the domain validated by your SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) signatures, ensuring the email is legitimately authorized.
