Mail delivery failed: returning message to sender

2 months ago

Hallo,

seit einiger Zeit erhalte ich eine Fehlermeldungsmail, wenn ich von meinem Handy aus eine Mail mit Anhang, von meinem Web.de Account an meine t-online-adresse schicke. Ohne Anhang kommt die Mail an.

Es wird geschrieben: for help or
to contact tosa@rx.t-online.de to clarify. (TEM)

Woran kann es liegen und was muss ich machen, damit es wieder funktioniert?

Danke für schnelle Hilfe.
