Findings

✕DMARC in monitoring mode only (p=none)

p=none provides reports but does not reject a single forgery. The goal is p=reject.
!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.
!DNSSEC not enabled

Without DNSSEC, DNS answers can be forged in transit. DANE requires DNSSEC.
!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.
