Findings

!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.
!MTA-STS disabled (mode: none)

The policy is explicitly switched off.
!No TLS reporting (TLS-RPT)

Without TLS-RPT the organisation does not learn when senders fail to deliver encrypted.
iStrict DMARC alignment

adkim=s or aspf=s requires exact domain matches. Secure, but demanding when sending from subdomains.
