Certificate Authority Authorization
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
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
No DKIM TXT with `v=DKIM1` was returned for the selector names we probe automatically.
SPF (Sender Policy Framework)
No SPF TXT record was returned (`v=spf1` / `spf2.0/`). SPF tells receivers which hosts may send mail for this domain; without it, aligned DMARC and spoofing defenses are weaker.
MTA-STS
This hostname does not publish an MTA-STS policy (no v=STSv1 TXT at _mta-sts.<name> and/or no policy at https://mta-sts.<name>/.well-known/mta-sts.txt).
