Hallo, ich habe folgendes Problem: Ich habe einen E-Mail-Server aufgesetzt.
Wenn ich eine E-Mail verschicken steht im header:
/etc/hosts:
/etc/hostname:
/etc/postfix/main.cf:
Vielleicht bin ich ja 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.
