Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.
DNS
Dual-stack
[2] 6/6/6 [O]
Meaning: Shows how many authoritative name servers exist, and how many IPv6 endpoints are configured, responsive, and operational.

Mail
Unknown
[1 MX] v4 smtp 0/0/0 v6 smtp 0/0/0 [I]
Meaning: Shows MX footprint and SMTP health per IP family. Operational means an SMTP banner and EHLO exchange succeeded on port 25.

Web
Unknown
[0] error: Get "https://www.flowgrenada.com/": context deadline exceeded
Meaning: Shows IPv6 web endpoint readiness for the discovered HTTPS host. Operational means family-specific HTTPS requests complete successfully.
IPv4 0/0/0 · IPv6 0/0/0 · location -
📌 Action item(s):
- Web measurement was inconclusive or unavailable.
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.flowgrenada.com (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Record at _dmarc.flowgrenada.com:
v=DMARC1; p=quarantine; sp=quarantine; rua=mailto:postmaster@flowgrenada.com
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
