    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns2.safebrands.eu (194.50.187.18): read udp 46.225.38.91:55415->194.50.187.18:53: i/o timeout; ns2.safebrands.eu (2a04:2b00:14dd::18): read udp [2a01:4f8:1c1c:eebf::1]:54006->[2a04:2b00:14dd::18]:53: i/o timeout; ns5.safebrands.tech (194.50.187.21): read udp 46.225.38.91:46635->194.50.187.21:53: i/o timeout; ns5.safebrands.tech (2a04:2b00:14dd::21): read udp [2a01:4f8:1c1c:eebf::1]:50152->[2a04:2b00:14dd::21]:53: i/o timeout.

    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.

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

    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: google (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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.
