Problems

• ✗

  No DKIM keys published

  DKIM · _domainkey.secunia.com does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.

  #7
• !

  Policy: quarantine

  DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

  #4
• !

  Not enabled

  DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

  #8
• !

  Single MX host, no backup

  MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

  #12
• !

  Applies to 10% of mail

  DMARC · DMARC policy only applies to 10% of failing mail (pct=10). Raise pct to 100 once you are confident in your setup.

  #18
• !

  Report address not authorized

  DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:DG-DMARC-FLX@flexera.com (needs secunia.com._report._dmarc.flexera.com). Ask the report provider to publish the record, or check the address.

  #29
• !

  Not configured

  TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
