Software version disclosed

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: nsauth1.bit.nl: "PowerDNS Authoritative Server 4.9.15 (built May 11 2026 09:10:06 by root@localhost)"; nsauth2.bit.nl: "PowerDNS Authoritative Server 4.9.15 (built May 11 2026 09:10:06 by root@localhost)"; nsauth3.bitnl.eu: "PowerDNS Authoritative Server 4.9.11 (built Oct 15 2025 10:16:15 by root@localhost)". Hide or replace the version string.

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.
