    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: ns1.net-server.de, ns2.net-server.de; only in the zone: pri-h2015.nbgo.de, sec-dns01.nbgo.de. ns1.net-server.de, ns2.net-server.de, pri-h2015.nbgo.de, sec-dns01.nbgo.de report NS pri-h2015.nbgo.de sec-dns01.nbgo.de.

    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns1.net-server.de (glue 87.237.124.6, zone 87.237.124.6, 2a02:420:0:3::3); ns2.net-server.de (glue 87.237.127.6, zone 87.237.127.6, 2a02:420:0:5::3). Update the glue at your registrar.

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: sec-dns01.nbgo.de: "9.16.23-RH". Hide or replace the version string.
    #17
  • !
    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026061702 on ns1.net-server.de (87.237.124.6), ns1.net-server.de (2a02:420:0:3::3), ns2.net-server.de (87.237.127.6), ns2.net-server.de (2a02:420:0:5::3); 2026101401 on pri-h2015.nbgo.de (185.146.238.79), pri-h2015.nbgo.de (2a02:420:0:8::900), sec-dns01.nbgo.de (185.146.238.254), sec-dns01.nbgo.de (2a02:420:0:10::2). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.
    #22
  • !
    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

  • !
    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
  • !
    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.fona.de
    #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
  • !
    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.
