Hallo Zusammen, Folgendes passierte heute:
Ich hatte in der macOS Apple Mail App auf eine Email geantwortet, die an meine [email protected] <mailto:[email protected]> Adresse adressiert war. Ich habe darauf ein reply gemacht. Eigentlich müßte sie doch an den Apple (me.com <http://me.com/>) mailserver direkt geliefert werden? Oder kann es sein, daß sie über meinen <my_server_ip> an apple und dann an gmail geliefert wurde? Ich habe jetzt DMARC , DKIM und SPF auf meinem mail server (die Adresse, von der ich hier poste) und trotzdem bounct die Email: This is the mail system at host mail.myserver.org. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message.
