Problems

✗

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.capitar.dnsprov.com (91.198.103.5): dial tcp 91.198.103.5:53: connect: connection refused.

#19
!

No IPv6

Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

#13
!

Software version disclosed

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.capitar.dnsprov.com: "9.11.3-1ubuntu1.18-Ubuntu"; ns1.capitar.dnsprov.de: "9.11.3-1ubuntu1.18-Ubuntu"; ns1.capitar.dnsprov.eu: "9.11.3-1ubuntu1.18-Ubuntu". Hide or replace the version string.

Problems

!

Single MX host, no backup

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

#12
!

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: selector1 (1024 bits). Rotate to a 2048-bit key.

#23
!

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.
