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

Dual-stack
[2] 6/6/6 [O]

Mail
Dual-stack
[1 MX] v4 smtp 4/4/4 v6 smtp 4/4/4 [O]
Meaning: Shows MX footprint and SMTP health per IP family. Operational means an SMTP banner and EHLO exchange succeeded on port 25.

Web
Dual-stack

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
p=quarantine
p=quarantine — published organizational policy. Ask receivers to quarantine failing mail; reject is stronger.
Meaning: Published DMARC policy at _dmarc.sprep.org (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Record at _dmarc.sprep.org:
v=DMARC1; p=quarantine; fo=s; rua=mailto:f12fd559825c46f2b2b321fba002141d@dmarc-reports.cloudflare.net; pct=100; sp=quarantine
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
