I'm having a similar problem with incorrectly sent attachments
turning into binXXXXX.bin files, as that mentioned in:
http://www.xray.mpe.mpg.de/mailing-lists/mhonarc/1998-06/msg00007.html
That is, Eudora seems to always send JPG, GIF and WAV files as
application/octet-stream. As an example:
Content-Type: application/octet-stream; name="Aerotech.wav"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="Aerotech.wav"
Rather than use the "usename" option of the external file filter,
I'd like to propose a new option of "useextension". Ideally,
this would be invoked for application/octet-stream and would
use the extension of the supplied file name to replace the "bin"
extension. I.e., the above would generate a file called
"binXXXXX.wav". This would make it easier for people to browse
the archive for these errantly sent messages.
