Findings
-
!SPF authorises very large IP ranges (65,554)
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.
-
!No MTA-STS
Without MTA-STS (or DANE) inbound encryption is not enforced; an attacker on the path can downgrade to plain text.
