Hallo, ich habe folgendes Problem: Ich habe einen E-Mail-Server mit modoboa aufgesetzt.
Wenn ich eine E-Mail verschicken steht im header:
Received: from localhost (ip6-localhost [127.0.0.1]) by mail.myDomain.com (Postfix) with ESMTP id 4C9457F997 for <lordfritte@googlemail.com>; Thu, ... Received: from mail.myDomain.com ([127.0.0.1]) by localhost (mail.myDomain.com [127.0.0.1]) (amavisd-new, port 10026) with ESMTP id 8MLvZKFWnD-r for <lordfritte@googlemail.com>; Thu,

Vielleicht bin ich aj auch auf dem Holzweg, das eigentlich Problem ist: ich habe bei mail-tester.com eine 10 von 10 und dennoch landen meine E-Mails bei Anbietern wie outlook/microsoft und gmail im Spam-Verzeichnis. Jetzt habe ich hier https://www.digitalocean.com/community/questions/email-sent-to-gmail-is-flagged-as-spam gelesen, es könnte am "Received: from localhost" liegen. Achja beim spf habe ich ein softFail.
