Findings

!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.
iDANE active (TLSA with DNSSEC)

All MX hosts publish TLSA records secured by DNSSEC.
iBIMI logo published

A brand logo for mail clients is published (without a certificate large providers do not show it).
