Hallo zusammen,
ich habe ein Phänomen: Mein Server akzeptiert die Mails der Ruhr-Uni Bochum nicht und gibt mir auch keinerlei Infos warum der SPF-Check negativ ausfällt.
Der Link zu openspf sagt folgendes:
mail@empfänger rejected a message that claimed an envelope sender address of sender@ruhr-uni-bochum.de. mail@empfänger received a message from out1.mail.ruhr-uni-bochum.de (2a05:3e00:8:1001::8693:3595) that claimed an envelope sender address of sender@ruhr-uni-bochum.de. The domain ruhr-uni-bochum.de has authorized out1.mail.ruhr-uni-bochum.de (2a05:3e00:8:1001::8693:3595) to send mail on its behalf, so the message should have been accepted. It is impossible for us to say why it was rejected. What should I do? If the problem persists, contact the ruhr-uni-bochum.de postmaster.

Hattet Ihr so etwas schon mal? Was kann ich tun? Der Postmaster der Ruhr-Uni reagiert nicht auf meine Anfrage. Hier der SPF-Record: ruhr-uni-bochum.de. 74421 IN TXT "v=spf1 exists:%{ir}.%{v}._spfx.ruhr-uni-bochum.de exists:%{ir}._ip.%{l}._spfx.ruhr-uni-bochum.de -all"
DNS, SPF und IPv6 funktionieren problemlos, habe echt keine Idee... :(
