Findings
-
!SPF authorises very large IP ranges (167,582)
The SPF record itself lists IPv4 ranges with more than 65,000 addresses. The wider the range, the easier it is for third parties to send from an authorised network.
-
!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.
