Dual-stack
[1 MX] v4 smtp 4/4/4 v6 smtp 4/4/4 [O]

📌 Action item(s):
- Publish AAAA records for web host: www.cavehill.uwi.edu.
DNSSEC
Unsigned
U/-/-
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.
Analyze on DNSViz
📌 Action item(s):
- Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.
DMARC
p=none
p=none — published organizational policy. Monitoring only (receivers should not reject mail); tighten toward quarantine, then reject when ready. Not the same as missing DMARC.
Meaning: Published DMARC policy at _dmarc.cavehill.uwi.edu (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Record at _dmarc.cavehill.uwi.edu:
v=DMARC1; p=none; rua=mailto:dmarcreports@cavehill.uwi.edu; ruf=mailto:dmarcreports@cavehill.uwi.edu; fo=1
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
Check on dmarcian
📌 Action item(s):
- DMARC is monitoring-only (p=none). Move toward quarantine, then reject. Review on dmarcian.
