Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.

Dual-stack
[3 MX] v4 smtp 3/3/3 v6 smtp 3/3/3 [O]

DNSSEC
Signed
S/?/? (partial)
Meaning: Shows whether DNSKEY data is observed at the apex (signed), absent (unsigned), or unavailable due to lookup error.
Apex DNSKEY presence only — not full chain validation.

DMARC
No record
No record — no TXT at _dmarc.picisoc.org.
Meaning: Published DMARC policy at _dmarc.picisoc.org (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Publish a DMARC TXT at _dmarc.picisoc.org (often start with p=none, then tighten).
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
Check on dmarcian
📌 Action item(s):
- Publish a _dmarc TXT record (start with p=none, then tighten). Check policy on dmarcian.
