Protection against forged senders: not protected

Points per criterion

  • MX 10 / 10
  • SPF 13 / 15
  • DKIM 20 / 20
  • DMARC 0 / 25
  • DNSSEC 0 / 10
  • Transport (MTA-STS/DANE) 12 / 15
  • TLS-RPT 0 / 5

Findings

  • ✕No DMARC record

    Without DMARC no receiver reliably rejects forged mail in the domain's name, and the organisation receives no abuse reports.

  • !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.

  • iDANE active (TLSA with DNSSEC)

    All MX hosts publish TLSA records secured by DNSSEC.
