Protection against forged senders: not protected (monitoring only)

Points per criterion

  • MX 10 / 10
  • SPF 15 / 15
  • DKIM 20 / 20
  • DMARC 6 / 25
  • DNSSEC 10 / 10
  • Transport (MTA-STS/DANE) 0 / 15
  • TLS-RPT 0 / 5

Findings

  • ✕DMARC in monitoring mode only (p=none)

    p=none provides reports but does not reject a single forgery. The goal is p=reject.

  • !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.
