Findings

✕No DMARC record

Without DMARC no receiver reliably rejects forged mail in the domain's name, and the organisation receives no abuse reports.
!SPF without a clear fail (?all or no all)

A neutral ending gives receivers no instruction on how to treat unknown servers.
!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.
!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.
