Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: dns1.level27.eu: "9.18.18-0ubuntu0.22.04.1-Ubuntu"; dns2.level27.eu: "9.18.39-0ubuntu0.24.04.5-Ubuntu"; dns3.level27.net: "9.18.39-0ubuntu0.24.04.3-Ubuntu". Hide or replace the version string.

DNSSEC · SHA-1 based algorithms are deprecated and rejected by some validators: RSASHA1-NSEC3-SHA1 (7). Roll over to ECDSAP256SHA256 (13).

SPF · SPF record uses ?all (neutral), which gives no protection against unauthorized senders. Use -all or ~all instead.

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

DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.

MX · The following MX hosts could not be resolved to IPv6 addresses: mail.appoint.be

MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

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.
