map_supply_chain

Active

declared in 3.29.5

Map DNS-visible third-party service dependencies for a domain. Correlates SPF, NS, TXT verifications, SRV services, and CAA records to reveal which third-party vendors can send email as the domain, control DNS, or access integrated services. Use when asked to map third-party or supply-chain dependencies — not for listing who can send email (use check_spf for that).
