No DNS over TCP

Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns1.argewebhosting.eu (31.25.98.210): read tcp 46.225.38.91:52006->31.25.98.210:53: i/o timeout; ns1.argewebhosting.eu (2a05:1500:702:0:1c00:eff:fe00:ce): read tcp [2a01:4f8:1c1c:eebf::1]:49780->[2a05:1500:702:0:1c00:eff:fe00:ce]:53: i/o timeout.

NSEC3 with extra iterations or salt

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.

Problems

✗

No DMARC record

DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.

#5
✗

No DKIM keys published

DKIM · _domainkey.detelefoongids.nl does not exist (SERVFAIL), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.

#7
!

Single MX host, no backup

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

#12
!

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.
