Anstatt E-Mail Absender und Empfänger stehen unsere Adressen.

Hallo,
ich habe das Problem, das ich von einigen Leuten keine Mails mit Anhang empfangen kann.Es sind aber komischerweise nur 2.
Immer wenn die mir eine Mail schicken bekomm ich anstatt des Anhanges nur folgendes:
Anstatt E-Mail Absender und Empfänger stehen unsere Adressen.
Meils ohne Abhang kann ich problemlos empfangen.
