Findings
-
!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.
-
!No MTA-STS
Without MTA-STS (or DANE) inbound encryption is not enforced; an attacker on the path can downgrade to plain text.
-
iDANE active (TLSA with DNSSEC)
All MX hosts publish TLSA records secured by DNSSEC.
