Hallo,
ich kann bei manchen Mails die Anhänge weder abtrennen noch löschen. Die entsprechenden Optionen sind ausgegraut. Soweit ich das sehe ist das bei allen Mails so, die von Apple Rechnern verschickt werden. Allerdings nicht beschränkt auf Apple Mail, auch bei Mails von Thunderbird auf Apple ist das der Fall. Dies ist der (anonymisierte) Quelltext einer solchen Mail:
