DNS and authentication

DNS verification failed

What a failed SPF, DKIM, DMARC or MX check means, why we query public resolvers, and how to fix BYO domains.

What failed

Open the domain → DNS. Each record shows expected vs observed. Observed is what public resolvers returned, not what our nameserver thinks.

Common BYO failures:

  • Nameservers not switched, or switched but not propagated
  • Old SPF still present, or too many includes (10-lookup limit)
  • DKIM hostnames copied with the domain twice (rsa._domainkey.example.com.example.com)
  • DMARC TXT missing at _dmarc
  • MX still pointing at Google/Microsoft while we expect EmailPal

Click recheck after you save at the DNS host. Propagation can take minutes to hours, not usually days.

FAQs

It is green for me in a lookup tool and red here.

Different resolvers, caching, or you queried our nameserver directly. We deliberately do not grade ourselves.

Registered through EmailPal and still red.

That is a provision/DNS job issue — open a ticket with the domain and screenshot of expected vs observed.
