Findings

!DMARC without reporting (no rua)

Without aggregate reports it stays invisible who sends in the domain's name.
!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.
iStrict DMARC alignment

adkim=s or aspf=s requires exact domain matches. Secure, but demanding when sending from subdomains.
