What this check tells you

SPF lists infrastructure authorized to send mail for a domain. A missing record, multiple SPF records, a permissive +all mechanism, or more than ten DNS lookups can make authentication ineffective or return a permanent error.

How to use the result

• Confirm the queried name is the exact hostname used by the affected service.
• Compare the returned values with the intended record in your authoritative DNS provider.
• Check TTL before changing records again; cached answers can outlive a rollback.
• Run the full domain report to correlate DNS with TLS, HTTP, routing, and provider incidents.

Queries use public DNS data. No account is required, and analytics never receives the domain you enter.
