Certificate Authority Authorization
TTL
No CAA records were returned at this registrable domain name. With no CAA policy, any public certificate authority (CA) may issue TLS certificates for names under this zone unless a parent publishes CAA; add issue / issuewild / iodef records to restrict issuance.
DMARC
TTL
No DMARC TXT record was returned (expected at `_dmarc.<domain>` with `v=DMARC1`). Without DMARC you cannot publish receiver policy or standard aggregate failure reports (RUA).
DKIM
TTL
No DKIM TXT with `v=DKIM1` was returned for the selector names we probe automatically.

SPF issues
- Token "all." looks like a hostname but SPF requires an explicit mechanism prefix (for example `a:all.`, `mx:all.`, or `include:all.`; see RFC 7208)
