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 close to the 10-lookup limit (8)

One more sending service can break the limit. Flattening or subdomains for third parties create headroom.
!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.
