Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns.mydnsserver.be: "PowerDNS Authoritative Server 5.1.5 (built Oct 21 2026 08:56:58 by root@localhost)". Hide or replace the version string.

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.

DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

MX · The following MX hosts could not be resolved to IPv6 addresses: d312445.a.ess.de.barracudanetworks.com, d312445.b.ess.de.barracudanetworks.com

DMARC · DMARC policy only applies to 20% of failing mail (pct=20). Raise pct to 100 once you are confident in your setup.

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: s2 (1024 bits). Rotate to a 2048-bit key.

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.
