Findings

!SPF close to the 10-lookup limit (9)

One more sending service can break the limit. Flattening or subdomains for third parties create headroom.
!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.
!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.
