Problems

  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: dns3.wmaker.net. dns1.wmaker.net, dns2.wmaker.net, dns3.wmaker.net report NS dns1.wmaker.net dns2.wmaker.net dns3.wmaker.net.
    #7
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: dns1.wmaker.net: "9.18.1"; dns2.wmaker.net: "9.18.1"; dns3.wmaker.net: "9.16.37-Debian". Hide or replace the version string.
    #17
  • !
    Unusual SOA timers
    SOA · refresh 10m is outside 20m–1d; retry 10m should be shorter than refresh 10m; expire 10m is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 10m must be longer than refresh + retry. Current values: refresh 10m, retry 10m, expire 10m, negative TTL 10m.
    #23
  • !
    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
  • !
    Uses deprecated ptr mechanism
    SPF · The ptr mechanism in SPF records is deprecated due to performance issues and should be avoided.
    #1
  • !
    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: smtp01.wmaker.net, smtp02.wmaker.net
    #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.
    #23
  • !
    Key in test mode
    DKIM · These keys have t=y, so receivers treat DKIM failures as a test: default. Remove t=y once DKIM works.
    #24
  • !
    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.
