Guten Tag,
auf unserer Domain weinstadt-tafel.de nutzen wir E_mail Service, um die ankommende E-Mails an die Privat-Adressen der User weiter zu leiten, ohne aktives Postfach. Seit ca. 2 Wochen werden ankommende E-Mails von T-Online Mailserver (194.25.134.80, 194.25.134.20) abgewiesen (Beispiel unten). Demnach sind die Server Blacklisted (?).
Wie lässt sich das Problem beheben?
