Problems

  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns3.cyberbrain.net (67.217.240.205): dial tcp 67.217.240.205:53: connect: connection refused.
    #19
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    No EDNS
    Nameservers · These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: ns1.cyberbrain.net (217.182.102.182), ns2.cyberbrain.net (5.135.201.100), ns3.cyberbrain.net (67.217.240.205).
    #20
  • !
    Unusual SOA timers
    SOA · retry 2h should be shorter than refresh 2h. Current values: refresh 2h, retry 2h, expire 14d, negative TTL 2h.
    #23
  • !
    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.
    #27

Problems

  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mx1.cyberbrain.net, mx2.cyberbrain.net
    #11
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits), mail (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.
