Wir können sicherheitskritische Einträge herausfiltern, jedoch nicht logische Fehler automatisch erkennen. Im Fehlerfall wird meistens Ihre gesamte Domain vom DNS-Server ausgeschlossen, so lange sich Fehler in der Konfiguration befinden. Sollten Sie hier also fehlerhafte Eintragungen machen, kann dies die Erreichbarkeit der betreffenden Domain im Ganzen stören.</p>');
