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.
iBIMI with mark certificate (VMC/CMC)

Logo with a verified mark certificate, shown by Gmail and Apple Mail among others. Requires DMARC enforcement.
