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

DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

SPF · The ptr mechanism in SPF records is deprecated due to performance issues and should be avoided.

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

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

MX · The following MX hosts could not be resolved to IPv6 addresses: mail.sozialpolitik-aktuell.de

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

MX · The PTR name of these addresses does not resolve back to the same address: 92.204.28.237 -> 237.28.204.92.host.secureserver.net.

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.
