Problems

  • !
    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns1.unix-solutions.be (glue 109.68.160.244, zone 109.68.160.244, 2a02:2a08:102::244). Update the glue at your registrar.
    #8
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.unix-solutions.be: "PowerDNS Authoritative Server 4.4.1"; ns2.unix-solutions.com: "PowerDNS Authoritative Server 4.4.1". Hide or replace the version string.
    #17
  • !
    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: 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
  • !
    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: zimbra01.unix-solutions.be
    #11
  • !
    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
  • !
    Broad IP ranges
    SPF · These ranges authorize tens of thousands of addresses or more: ip6:2a04:6480::/29. Check that you really own and send from all of them.
    #27
  • !
    Reverse DNS does not match
    MX · The PTR name of these addresses does not resolve back to the same address: 2a04:6480:101::201 -> mx2.unix-solutions.be.
    #30
  • !
    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.
