Findings
-
✕DMARC in monitoring mode only (p=none)
p=none provides reports but does not reject a single forgery. The goal is p=reject.
-
!SPF close to the 10-lookup limit (10)
One more sending service can break the limit. Flattening or subdomains for third parties create headroom.
-
!DNSSEC not enabled
Without DNSSEC, DNS answers can be forged in transit. DANE requires DNSSEC.
-
!No MTA-STS
Without MTA-STS (or DANE) inbound encryption is not enforced; an attacker on the path can downgrade to plain text.
-
!No TLS reporting (TLS-RPT)
Without TLS-RPT the organisation does not learn when senders fail to deliver encrypted.
