Findings
-
!Subdomains unprotected (sp=none)
The main domain is protected, but subdomains such as invoice.company.ch can still be forged.
-
!External report receiver not authorised
The authorisation record for an external rua domain is missing (RFC 7489 §7.1); many receivers then send no reports.
-
!DKIM key below 2048 bits
RSA-1024 is considered too weak (RFC 8301, M3AAWG). Rotate to 2048-bit keys.
-
!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.
