  • !
    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026102132 on dns-2.witcom.de (212.43.68.10), dns-2.witcom.de (2a01:5c0:4::4); 2026102133 on dns-1.witcom.de (217.19.176.2), dns-1.witcom.de (2a00:1f08:800::2), pns.dtag.de (194.25.0.125), pns.dtag.de (2003:40:8000::100); 2026102140 on secondary004.dtag.net (195.244.245.27), secondary004.dtag.net (2a00:fa8:3:0:100:0:4:1). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

    No key under common selectors

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mail101.ruv.de, mail102.ruv.de, mail103.ruv.de, mail201.ruv.de, mail202.ruv.de, mail203.ruv.de

    More than 5 MX records
    MX · Found 6 MX records, which is more than the recommended maximum of 5. Too many MX records may indicate a misconfiguration.

  • !
    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.
