Findings
-
!DMARC without reporting (no rua)
Without aggregate reports it stays invisible who sends in the domain's name.
-
!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.
