Summary
The bounce message "554 5.7.5 Permanent Error Evaluating DMARC Policy" indicates a fundamental issue with how a receiving mail server is able to process your domain's DMARC record. Unlike a simple DMARC rejection, which occurs when an email fails authentication against a readable DMARC policy, this error suggests the policy itself cannot be properly evaluated. This is often due to a malformed DMARC record in your DNS, preventing the recipient server from parsing it correctly.
Key findings
- Evaluation failure: The error implies the receiving server cannot evaluate the DMARC policy for emails sent from your domain, rather than a failure to pass authentication against an existing policy.
- Malformed record: The primary cause is typically a DMARC record that is syntactically incorrect or contains errors in its DNS configuration.
- DNS issues: Problems such as multiple DMARC records for a single domain or incorrect formatting (e.g., missing 'mailto:' in RUA declarations) can lead to this permanent error.
- Distinction: This bounce is different from a regular DMARC rejection, which indicates a successful policy lookup but a failure in SPF or DKIM alignment.
Key considerations
- Verify syntax: Carefully check your DMARC TXT record for any typos, missing characters, or extra elements that could cause parsing errors. You can use a DMARC record generator tool to help ensure correctness.
- Single record rule: Ensure there is only one DMARC record published for your domain. Multiple records will lead to evaluation failures.
- RUA/RUF formatting: Confirm that your DMARC tags, particularly 'rua' and 'ruf' (reporting addresses), include the 'mailto:' prefix as required.
- DNS propagation: After making any DNS changes, allow sufficient time for them to propagate across the internet before retesting.
What email marketers say
Email marketers often encounter the "Permanent Error Evaluating DMARC Policy" bounce and generally attribute it to incorrect DMARC record configuration. Their experiences highlight the sensitivity of DMARC records to even minor syntax errors or unintended duplicates within the DNS.
Key opinions
- Malformed records: The consensus among marketers is that this error points directly to a malformed DMARC record in the DNS.
- Syntax sensitivity: Small errors, such as extra dots or the omission of 'mailto:' in reporting tags, are frequently cited as culprits. The Automated Email Warm Up blog advises removing unnecessary characters.
- Multiple entries: Having more than one DMARC TXT record for a domain is a known configuration mistake that can trigger this error.
- DNS lookup: Some marketers suggest that the error could also be a symptom of a broader DNS lookup failure preventing the recipient server from finding the DMARC record.
Key considerations
- Validation tools: Utilize online DMARC validation tools to quickly identify and correct syntax errors in your DMARC record. This is crucial for avoiding DMARC failures.
- Regular DNS audits: Periodically audit your domain's DNS records to ensure no duplicate or erroneous DMARC entries exist.
- Check tags: Double-check the formatting of all DMARC tags, especially the 'p' (policy), 'rua' (aggregate reports), and 'ruf' (forensic reports) tags, as minor deviations can cause evaluation issues. Refer to DMARC record examples.
- Consult ESP support: If you use an Email Service Provider, consult their documentation or support for DMARC setup best practices to avoid common misconfigurations.
Marketer view
Marketer from Email Geeks points out the distinct nature of the "Permanent Error Evaluating DMARC Policy" bounce, suggesting it implies Google cannot read or parse the DMARC policy due to DNS or malformation issues. This wording is different from a simple DMARC rejection, which means the policy was understood but authentication failed. The key distinction lies in the ability of the recipient's mail server to even interpret the policy.
Marketer view
Marketer from Automated Email Warm Up advises removing unnecessary characters from your DNS record as a quick fix for the "554 5.7.5 Permanent Error Evaluating DMARC Policy". This highlights that subtle syntax errors or extraneous elements in the DMARC TXT record can directly cause this evaluation failure. Clean and precise DNS entries are critical for DMARC parsing.
What the experts say
Email deliverability experts agree that the "Permanent Error Evaluating DMARC Policy" bounce is a strong indicator of a malformed or improperly configured DMARC record in the DNS. They emphasize that this error signifies a parsing issue rather than an authentication failure, pointing to specific syntax problems that prevent the receiving server from even reading the policy.
Key opinions
- DNS malformation: A DMARC policy in DNS that is not correctly formed is the most commonly cited reason for this permanent evaluation error.
- Specific syntax issues: Errors such as missing 'mailto:' in 'rua' or 'ruf' declarations, or the presence of extra characters, are critical causes. This highlights the importance of precise DMARC, SPF, and DKIM configuration.
- Receiver specific: While observed with Google, other mail servers like Proofpoint also issue similar bounces, indicating a broader issue with DMARC record parsing across various email providers.
- Temporary vs. permanent: A temporary error (451) might suggest a transient DNS lookup problem, whereas a permanent error (554) points to a fundamental and persistent issue with the DMARC record itself. Understanding this distinction is key to troubleshooting DMARC failures.
Key considerations
- RFC adherence: Ensure your DMARC records strictly conform to RFC specifications. Even minor non-compliance can lead to evaluation failures by recipient mail servers.
- Single record: It is crucial to have only one DMARC TXT record for the _dmarc.yourdomain.com hostname. Multiple records will create ambiguity and cause errors.
- Monitor reports: Regularly review your DMARC aggregate and forensic reports to identify domains experiencing evaluation issues. These reports provide invaluable insight for demystifying SPF TempErrors and other related problems.
- Proactive validation: Implement automated tools or services to continually validate your DMARC record's integrity and proactively alert you to any malformations or DNS issues.
Expert view
Expert from Email Geeks suggests checking logs for DNS issues related to the domain experiencing the "Permanent Error Evaluating DMARC Policy" bounce. This indicates that the error might be tied to how the receiving mail server's DNS resolver interacts with the sender's DMARC record, emphasizing the need to diagnose network-level problems.
Expert view
Deliverability expert from SpamResource emphasizes the critical importance of a correctly formatted DMARC record for successful email delivery and policy enforcement. They highlight that any deviation from the standard can lead to rejection or evaluation errors, underscoring the necessity of precision in DNS configurations.
What the documentation says
Official DMARC documentation and related RFCs define the precise structure and processing rules for DMARC records. These specifications shed light on why a "Permanent Error Evaluating DMARC Policy" occurs: when a record deviates from the standard, recipient mail servers cannot correctly parse or interpret the policy, leading to an evaluation failure.
Key findings
- Strict format: The DMARC standard (RFC 7489) outlines specific, mandatory requirements for DMARC policy records to be published in DNS. Any deviation leads to issues.
- Parsing requirement: Receiving mail servers are designed to parse the DMARC TXT record according to the RFC. A malformed record is simply unreadable. Mailgun's documentation on implementing DMARC highlights proper setup.
- Syntax sensitivity: Minor syntax errors, extra characters, or missing mandatory tags can prevent the record from being correctly interpreted, resulting in an evaluation error.
- DNS resolution: The ability to retrieve the DMARC record from DNS is fundamental to its evaluation. Failures in DNS lookup, including issues with DMARC policy not enabled warnings, prevent policy application.
Key considerations
- RFC compliance: Ensure your DMARC record strictly adheres to the specifications outlined in RFC 7489. Any deviation, no matter how small, can lead to issues in policy evaluation. Understanding DMARC record and policy examples can help.
- TXT record limits: Be mindful of DNS TXT record length limitations and character set requirements, as exceeding these can cause parsing issues for some mail servers.
- Automated checks: Leverage tools that automatically check the validity and syntax of your DMARC, SPF, and DKIM records to prevent such permanent errors from occurring.
- Error handling: Recognize that receiving servers, when unable to evaluate a DMARC policy, will typically return a hard bounce, meaning the email will not be delivered.
