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
DMARC Policy

Organizational policy (p): how receivers treat mail that fails aligned DMARC checks — none (monitor only), quarantine (often junk), or reject (block).

none quarantine reject
5m
DMARC Subdomain Policy

Subdomain policy (sp): when set, it applies to hostnames below this domain instead of p; if omitted, subdomains inherit the organizational policy.

none quarantine reject
DMARC Percentage

pct: share of mail that gets quarantine/reject; 100 = all failing messages (default).

100
DMARC RUA

Aggregate DMARC reports (ZIP/XML). Optional but recommended for visibility.

No aggregate report URIs (RUA).
DMARC RUF

Forensic (per-failure) reports. Often omitted for privacy or volume.

No forensic report URIs (RUF).

DKIM

TTL

No DKIM TXT with `v=DKIM1` was returned for the selector names we probe automatically.

SPF (Sender Policy Framework)

TTL

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

TTL

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).
