Findings

✕SPF exceeds 10 DNS lookups (12)

More than ten lookups (include, a, mx, ptr, exists, redirect) cause a permerror; many receivers then treat SPF as failed.
!SPF authorises very large IP ranges (81,942)

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.
!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.
