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 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.

mailto:[email protected]
DMARC RUF

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

mailto:[email protected]

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).
