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

📌 Action item(s):
- Publish AAAA records for web host: www.cbaruba.org.
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.cbaruba.org (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Record at _dmarc.cbaruba.org:
v=DMARC1; p=quarantine; rua=mailto:dmarc@cbaruba.org; ruf=mailto:dmarc@cbaruba.org; sp=quarantine; fo=1:d:s; adkim=r; aspf=r
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.

📌 Action item(s):
- Tighten DMARC toward p=reject when ready. Review on dmarcian.
