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 (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).
