Findings
-
!DMARC without reporting (no rua)
Without aggregate reports it stays invisible who sends in the domain's name.
-
!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.
-
iStrict DMARC alignment
adkim=s or aspf=s requires exact domain matches. Secure, but demanding when sending from subdomains.
