Software version disclosed

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: dimitris.ns.cloudflare.com: "2026.10.2"; irena.ns.cloudflare.com: "2026.10.2". Hide or replace the version string.

Problems

!

Hosts without IPv6

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

#11
!

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
!

1024-bit DKIM key

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

#23
!

Addresses without reverse DNS

MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 37.252.124.162 (mail.zorgkaartnederland.nl). Ask your hosting provider to set one.

#30
!

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.

#32
!

No certificate (a=)

BIMI · The logo is published without a Verified Mark Certificate. Gmail and Apple Mail only show BIMI logos with a VMC or CMC; Yahoo shows it without one.
