Knowledge Base & Operational DocumentationWhy Does a Domain’s Website Work but Its Email Records Fail Validation?
Web and mail services can use different DNS records and providers. A site may load correctly while MX, SPF, DKIM, or DMARC records are missing, duplicated, or published in a zone that is not authoritative.
What to check
Query authoritative nameservers for mail records, confirm the exact hostname and TXT values, and compare with the active mail provider’s setup instructions. Check for multiple SPF records and outdated verification entries.
Recommended next step
Correct mail records in the authoritative zone and preserve unrelated service values. Validate inbound routing and message authentication separately, then monitor delivery after propagation.
