SPF Lookup / Flattening Risk
Evaluate a domain's published SPF record — syntax validity, DNS lookup pressure against the RFC 7208 10-term evaluation limit, include/redirect dependency chain, void lookups, and flattening suitability. This tool analyzes the published policy only — it does not evaluate whether any particular message passes SPF, since that depends on a sending IP address this diagnostic does not have.
