    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-suspended.zxcs.nl (185.104.28.27): read tcp 46.225.38.91:59056->185.104.28.27:53: i/o timeout; ns1-suspended.zxcs.nl (2a06:2ec0:1::eeeb): read tcp [2a01:4f8:1c1c:eebf::1]:33428->[2a06:2ec0:1::eeeb]:53: i/o timeout; ns2-suspended.zxcs.be (185.104.28.27): read tcp 46.225.38.91:59052->185.104.28.27:53: i/o timeout; ns2-suspended.zxcs.be (2a06:2ec0:1::eeeb): read tcp [2a01:4f8:1c1c:eebf::1]:33436->[2a06:2ec0:1::eeeb]:53: i/o timeout; ns3-suspended.zxcs.de (185.104.28.27): read tcp 46.225.38.91:59060->185.104.28.27:53: i/o timeout; ns3-suspended.zxcs.de (2a06:2ec0:1::eeeb): read tcp [2a01:4f8:1c1c:eebf::1]:33418->[2a06:2ec0:1::eeeb]:53: i/o timeout.

    Nameservers in one network
    Delegation · all IPv4 addresses are in 185.104.28.0/24; all IPv6 addresses are in 2a06:2ec0:1::/48. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).
    #10
  • !
    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 (2m), AAAA (2m), MX (2m). 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

  • ✗
    No DMARC record
    DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.
    #5
  • ✗
    No SPF record
    SPF · No SPF record was found for this domain. SPF is important for preventing email spoofing. Add an SPF record to specify which servers are authorized to send email for your domain.

  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
    #7
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8

    Hosts without IP addresses
    MX · The following MX hosts could not be resolved to IP addresses: mail.suspended-domain.com
    #10
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mail.suspended-domain.com
    #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
  • !
    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.
