Problems

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.contabo.net: "PowerDNS Authoritative Server 5.0.8 (built Oct 7 2026 06:11:14 by root@localhost)"; ns2.contabo.net: "PowerDNS Authoritative Server 5.0.8 (built Oct 7 2026 06:11:14 by root@localhost)"; ns3.contabo.net: "PowerDNS Authoritative Server 5.0.8 (built Oct 7 2026 06:11:14 by root@localhost)". Hide or replace the version string.

    Serials differ
    SOA · The nameservers serve different versions of the zone: 1792677686 on ns1.contabo.net (5.180.150.13), ns1.contabo.net (2a02:c207:ff00:1200::1), ns3.contabo.net (209.126.15.15), ns3.contabo.net (2605:a140:5028:1200::1); 1792677687 on ns2.contabo.net (195.179.224.10), ns2.contabo.net (2a02:c202:5028:1200::1). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

  • !
    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

  • ✗
    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.
    #6
  • !
    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 IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mail.jimmyb.nl
    #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.
