Findings

!Subdomains unprotected (sp=none)

The main domain is protected, but subdomains such as invoice.company.ch can still be forged.
!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.
!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.
