    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns01.x2com.nl: "PowerDNS Authoritative Server 5.0.8 (built Oct 7 2026 06:11:55 by root@localhost)"; ns02.x2com.eu: "PowerDNS Authoritative Server 5.0.8 (built Oct 7 2026 06:11:55 by root@localhost)"; ns03.x2com.net: "PowerDNS Authoritative Server 5.0.8 (built Oct 7 2026 06:11:55 by root@localhost)". Hide or replace the version string.

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.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: d327631.a.ess.de.barracudanetworks.com, d327631.b.ess.de.barracudanetworks.com

    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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.
