  • ✗
    Zone transfer allowed
    Nameservers · These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: avalon.iks-jena.de (217.17.192.66): 4695 records; avalon.iks-jena.de (2001:4bd8:0:104:217:17:192:66): 4695 records. Restrict zone transfers to your secondary servers.

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: avalon.iks-jena.de: "9.18.24". Hide or replace the version string.
    #17
  • !
    Deprecated algorithm
    DNSSEC · SHA-1 based algorithms are deprecated and rejected by some validators: RSASHA1 (5). Roll over to ECDSAP256SHA256 (13).

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 DKIM keys published
    DKIM · _domainkey.iks-jena.de does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    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.
    #32
  • !
    Not configured
    TLS · MTA-STS or DANE is used without TLS-RPT, so you get no reports when senders fail to deliver because of TLS problems. Publish _smtp._tls TXT "v=TLSRPTv1; rua=mailto:...".
