Problems

  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: dns.dns1.de (95.130.16.246): NOERROR, authoritative=true; dns.dns2.de (95.130.17.218): NOERROR, authoritative=true.
    #15
  • ✗
    Open recursion
    Nameservers · These nameservers resolve names for anyone, which makes them usable for DNS amplification attacks and cache poisoning: dns.dns2.de (95.130.17.218). Disable recursion on authoritative servers.
    #16
  • ✗
    CNAME at the apex
    Records · The zone apex is a CNAME to cbNimgdjmgdbiecj1.bw24.de. A CNAME can't coexist with the SOA and NS records (RFC 1034); use your provider's ALIAS/flattening feature instead.
    #33
  • !
    No EDNS
    Nameservers · These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: dns.dns1.de (95.130.16.246), dns.dns2.de (95.130.17.218).
    #20
  • !
    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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    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.
