This also happens when using Firefox to upload attachments to webmail services (eg. Yahoo) AppleMail, Entourage, Safari and Internet Explorer all upload/attach the same file as application/ms-word or application/octet-stream. Reproducible: Always Steps to Reproduce: 1. Create a short Microsoft word document 2. Attach to a new email using Thunderbird, or Yahoo from Firefox 3. Send to yourself. Note the Content Type header in the raw message source. Actual Results: Content Type: application/applefile Expected Results: Content Type: application/ms-word Most email clients (including TB) can decode the resulting attachment. Entourage can not, and produces a zero length file.
I can't confirm this report. A word document attachment appears with the following attachment headers. Content-Type: application/msword; name="filename.doc" Mac OS X 10.4.11; Thunderbird 184.108.40.206
Further investigation shows incorrect entries in the mimeTypes.rdf files in both the Firefox and Thunderbird profiles on the four machines found so far with this error. I haven't been able to find out where these incorrect 'applefile' entries originate. Deleting the rdf files solves the problem.
