Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.openprovider.nl: "2026.10.8"; ns2.openprovider.be: "2026.10.8"; ns3.openprovider.eu: "2026.10.8". Hide or replace the version string.

DNSSEC · NSEC3 uses 1 iteration and a 1-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

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

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: dkim (1024 bits), selector1 (1024 bits). Rotate to a 2048-bit key.

DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:domeinen@pricewise.com (needs pricewise.nl._report._dmarc.pricewise.com). Ask the report provider to publish the record, or check the address.

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.
