Problems

✗

Nameservers not responding

Nameservers · These addresses did not answer, so resolvers waste time on timeouts: a.it.nrw (93.184.132.50): read udp 46.225.38.91:37179->93.184.132.50:53: i/o timeout.

#14
✗

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: b.nrw.de (93.184.128.141): read tcp 46.225.38.91:47886->93.184.128.141:53: i/o timeout.

Problems

✗

Policy: none (monitoring only)

DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.

#4
!

Not enabled

DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

#8
!

Hosts without IPv6

MX · The following MX hosts could not be resolved to IPv6 addresses: postamt.it.nrw.de

#11
!

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
!

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.
