  • ✗
    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.proxgroup.fr (45.155.168.17): dial tcp 45.155.168.17:53: i/o timeout; ns2.proxgroup.fr (45.155.168.18): dial tcp 45.155.168.18:53: i/o timeout; ns3.proxgroup.fr (45.155.168.17): dial tcp 45.155.168.17:53: i/o timeout; ns4.proxgroup.fr (45.155.168.18): dial tcp 45.155.168.18:53: i/o timeout.

    Nameservers in one network
    Delegation · all IPv4 addresses are in 45.155.168.0/24. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).
    #10
  • !
    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.proxgroup.fr: "9.18.30-0ubuntu0.20.04.2-Ubuntu"; ns2.proxgroup.fr: "9.18.30-0ubuntu0.20.04.2-Ubuntu"; ns3.proxgroup.fr: "9.18.30-0ubuntu0.20.04.2-Ubuntu"; ns4.proxgroup.fr: "9.18.30-0ubuntu0.20.04.2-Ubuntu". Hide or replace the version string.

  • !
    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: A (1m), MX (1m), NS (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1m; resolvers may use either.

Problems

  • ✗
    12 DNS lookups, over the limit of 10
    SPF · SPF record needs 12 DNS lookups (including nested includes), more than the limit of 10. Receivers will return a permerror; reduce includes or flatten the record.

    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.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: srv.museeduchocolat.fr
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    No aggregate reports (rua)
    DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...
    #19
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (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.
