Findings

!No DKIM key found

No key was found under more than 100 common selectors. A custom selector is possible, but without DKIM there is no cryptographic sender check.
!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.
