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: ns1.o2switch.net (109.234.160.5): dial tcp 109.234.160.5:53: i/o timeout; ns2.o2switch.net (109.234.161.5): dial tcp 109.234.161.5:53: i/o timeout.
    #19
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.o2switch.net: "PowerDNS Authoritative Server 4.9.17 (built Aug 10 2026 00:00:00 by root@bh-centos-9.dev.cpanel.net)"; ns2.o2switch.net: "PowerDNS Authoritative Server 4.9.17 (built Aug 10 2026 00:00:00 by root@bh-centos-9.dev.cpanel.net)". Hide or replace the version string.
    #17
  • !
    Unusual SOA timers
    SOA · retry 2h should be shorter than refresh 1h. Current values: refresh 1h, retry 2h, expire 14d, negative TTL 1d.
    #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
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: MX (30s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1d; resolvers may use either.

Problems

  • !
    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
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mx-01-eu-west-1.prod.hydra.sophos.com, mx-02-eu-west-1.prod.hydra.sophos.com
    #11
  • !
    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.
