Problems

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: dns.fh-trier.de: "0.0.0". Hide or replace the version string.

  • !
    Serial date in the future
    SOA · The serial 2026102333 looks like a date (YYYYMMDDnn) in the future (2026-10-23). It can only grow, so a wrong date can't be undone without a serial wrap-around.

Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • ✗
    Policy not reachable
    TLS · The MTA-STS record exists but the policy could not be fetched, so senders ignore MTA-STS: Get "https://mta-sts.hochschule-trier.de/.well-known/mta-sts.txt": context deadline exceeded (Client.Timeout exceeded while awaiting headers).
    #33
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: gateway-a.fh-trier.de, gateway-b.fh-trier.de
    #11
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits). Rotate to a 2048-bit key.
