A DMARC TempError means the receiver could not retrieve your DMARC record due to a transient DNS issue. The receiver typically applies a default policy and may retry — but persistent TempErrors weaken DMARC enforcement.
Verify your _dmarc TXT record is reachable from public resolvers and that no DNS rate limiting or NXDOMAIN responses occur.
When a receiver evaluates DMARC, it queries _dmarc.yourdomain.com for the policy record. If that lookup returns SERVFAIL, times out, or hits another transient failure, the receiver records "DMARC TempError." Different receivers handle this differently — some apply your last-known policy, some default to p=none, others defer.
A TempError means your DMARC policy may not be enforced at the moment of evaluation, leaving you exposed to spoofing attempts during the failure window. It also pollutes your DMARC aggregate reports with non-actionable noise, and can undermine BIMI eligibility and sender reputation.
Query _dmarc.yourdomain.com against public resolvers and your authoritative nameservers.
dig @8.8.8.8 TXT _dmarc.yourdomain.com
dig @1.1.1.1 TXT _dmarc.yourdomain.com
dig +trace TXT _dmarc.yourdomain.comList your domain's NS records and query each one directly. If any nameserver is slow, returns SERVFAIL, or doesn't respond, contact your DNS provider.
dig NS yourdomain.com
dig @ns1.yourdnsprovider.com TXT _dmarc.yourdomain.comIf _dmarc.yourdomain.com is a CNAME to another domain, you double the DNS resolution chain. Replace with a direct TXT record where possible.
Free or shared DNS providers occasionally throttle high-volume queriers. If your domain receives a lot of email, ensure your DNS provider can handle production query volumes.
After fixing, ensure aggregate reports from Google, Yahoo, and Microsoft show "policy_evaluated" with a real disposition rather than blank or null entries indicative of TempError.
After making changes, use our free scanner to verify the fix is working correctly. DNS changes can take up to 48 hours to propagate, but most propagate within minutes.
Not necessarily. Many receivers fall back to a default policy (often p=none) or retry on TempError. But it does mean DMARC enforcement is unreliable during the failure window.
TempErrors typically come from transient DNS issues: nameserver slowness, intermittent network failure, resolver-specific outages, or occasional rate limiting. Reproduce across multiple resolvers and times to identify the pattern.
Yes. The record is published correctly, but the lookup itself is failing. The cause is on the DNS side — nameserver outage, CNAME chain timeout, or provider rate limiting — not the record content.
