    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.site.eu: "PowerDNS Authoritative Server 5.0.8 (built Oct 7 2026 06:11:55 by root@localhost)"; ns2.site.nl: "PowerDNS Authoritative Server 5.0.8 (built Oct 7 2026 06:11:55 by root@localhost)"; ns3.site.be: "PowerDNS Authoritative Server 5.0.8 (built Oct 7 2026 06:11:55 by root@localhost)"; ns4.site.de: "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.
    #4
  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
    #7
  • !
    No aggregate reports (rua)
    DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...
    #19
  • !
    Subdomains unprotected (sp=none)
    DMARC · DMARC subdomain policy is sp=none, so spoofed mail from subdomains is not blocked. Consider sp=quarantine or sp=reject.
    #20
  • !
    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.
