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
!

No key under common selectors

DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.

#7
!

Hosts without IPv6

MX · The following MX hosts could not be resolved to IPv6 addresses: statler.netto-online.de, waldorf.netto-online.de

#11
!

Signatures expire in 60h0m0s

DNSSEC · DNSKEY signatures expire at 2026-10-24T11:04:51Z (in 60h0m0s). Check that re-signing works.

#21
!

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.
