Was tun bei einem Eintrag?

  1. Ursache finden: Gehacktes E-Mail-Konto, unsicheres Kontaktformular, Schadsoftware auf dem Server oder ein offenes Mail-Relay sind die häufigsten Gründe.
  2. Problem beheben: Passwörter ändern, Software aktualisieren, Spam-Versand stoppen. Vorher nicht austragen lassen – sonst landest du sofort wieder auf der Liste.
  3. SPF, DKIM und DMARC für deine Domain einrichten bzw. prüfen.
  4. Austragung beantragen: Über den Link „Austragung beantragen“ bei der jeweiligen Liste. Viele Listen tragen automatisch nach einigen Tagen aus.
  5. Erneut prüfen – hier mit „Neu prüfen“.
