When I delete or detach, everything runs as if it was working, but after the operation, the email size is unchanged, and when I check the mail text file (inbox file), the data are still there, and thus not deleted. The header displays: ... X-Mailer: Apple Mail (2.753) ... Content-Type: multipart/mixed; boundary="===============1134621355==" Status: O X-UID: 573 Content-Length: 1739382 Reproducible: Sometimes Steps to Reproduce: 1. Open Thunderbird 2. Find an email sent by a Mac OS-X user 3. Try to delete, or detach an attached file Actual Results: The attached file won't be deleted, and its content still in the Inbox file. Expected Results: The attached file content is expected to be deleted from the Inbox file.

Hello lyu, sorry for *very* late reply. do yous still have the issue if you do, could you please save one of those emails in the .eml format and attach it to this bug ? (Et si t'as habité Nancy étant jeune - tt le meilleur copain de mon cousin samy)

It seems closely a dupe of bug #417646. Lyu, feel free to reopen it if I'm wrong.
