Findings
-
!SPF close to the 10-lookup limit (8)
One more sending service can break the limit. Flattening or subdomains for third parties create headroom.
-
!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.
