Protection against forged senders: largely protected, with a gap: subdomains not protected (sp=none)

Points per criterion

  • MX 10 / 10
  • SPF 15 / 15
  • DKIM 20 / 20
  • DMARC 19 / 25
  • DNSSEC 10 / 10
  • Transport (MTA-STS/DANE) 12 / 15
  • TLS-RPT 0 / 5

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.

  • iDANE active (TLSA with DNSSEC)

    All MX hosts publish TLSA records secured by DNSSEC.
