Common Causes Of 554 5.7.5 Errors
554 5.7.5 errors often happen due to issues with the DMARC policy. One common cause is a wrong DMARC record in DNS. This record must be correct and well-formed.
Sometimes, the DMARC policy is set to reject or quarantine but without proper SPF or DKIM alignment. This misalignment triggers the error.
Other causes include missing or invalid SPF and DKIM records. These records help verify the sender’s identity.
| Cause | Explanation |
|---|---|
| Incorrect DMARC record | Record has syntax errors or wrong values in DNS |
| SPF/DKIM misalignment | Policy set to reject/quarantine but fails verification |
| Missing SPF or DKIM | Sender’s domain lacks these essential authentication records |

How Dmarc Policy Impacts Email Delivery
DMARC policy tells email servers how to handle messages from your domain. It helps stop fake emails and phishing attacks. If the policy is strict, some emails might get blocked or marked as spam. This can cause a 554 5.7.5 permanent error, which means the email is rejected.
Strong DMARC policies improve email security but may lower delivery if records are not set properly. Correct setup of SPF and DKIM is needed to pass DMARC checks. If these fail, the email server will reject the message based on your DMARC rules.
Check your DNS records often. Make sure SPF and DKIM records match your sending servers. Keep your DMARC policy updated but test changes carefully to avoid blocking good emails.
Steps To Diagnose Dmarc Evaluation Issues
Check the DMARC record in DNS to ensure it is present and correct. Use tools like MXToolbox or DMARC Analyzer for quick verification. Confirm the policy syntax follows the standard format and does not contain errors.
Verify the alignment between SPF and DKIM with the domain in the From address. Mismatched domains cause DMARC failures. Check SPF and DKIM records separately to confirm they are valid.
| Step | What to Check | Why It Matters |
|---|---|---|
| 1 | DMARC Record Presence | Ensures policy is available for evaluation |
| 2 | Record Syntax | Prevents parsing errors |
| 3 | SPF and DKIM Alignment | Ensures emails pass authentication |
| 4 | DNS Propagation | Confirms updated records are live |
Make sure DNS changes have fully propagated. Sometimes updates take time to appear globally. Use DNS lookup tools to confirm the latest version is active.
