Undelivered Mail Returned to Sender

5 years ago

Hallo, häufig bekomme ich beim Versenden einer Mail (@t-online.de per Outlook) an einen guten Bekannten (@yahoo) die Fehlermeldung Undelivered Mail Returned to Sender. Aber meist erst nach 2 Tagen! Dazwischen funktioniert es wieder einwandfrei an den selben Adressaten. Wenn ich dann die unzustellbare Mail mit WG: nochmals schicke, klappt es wieder! Und meist sind es Mails mit Anhängen.

Die Meldung hat folgenden Wortlaut:

> Am 27.05.2020 um 08:15 schrieb Mail Delivery System <MAILER-DAEMON@mailout08.t-online.de>:

Der o.a. help/yahoo-Link hilft mir leider gar nicht weiter.

 

Hat wer von Euch einen Hinweis, was ich da machen kann?

Vielen Dank
