Findings
-
!SPF close to the 10-lookup limit (8)
One more sending service can break the limit. Flattening or subdomains for third parties create headroom.
-
!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.
