154406 - Attachment "save as type" useless for unrecognized file types/extensions

Status: VERIFIED DUPLICATE of bug 120327

(MailNews Core :: Attachments, defect)

Description

[Jeff Morriss]

I receive a lot of emails (to Mozilla 1.0 on Windows 2000) with plain text files
from Unix boxes attached.  Most of the time, these attachments do not follow the
typical Windows-style naming convention (e.g., they have names like "myfile.600"
instead of "myfile.txt" or similar).

Double clicking on these files in Mail causes the "Save as" dialog to appear and
I can select where I want the file to go, etc.  Oddly, the default extension for
such attached files is ".exe" (as shown in "Save as type" area).  I don't think
that makes sense, but that's fine...

What *is* wrong, though is that if I change the "Save as type" to be "All files"
(hoping to remove the ".exe" extension) the file is still saved as
"myfile.600.exe".  (Normally I'm saving these files back to Unix so I don't
really want to add ".txt" or any extension.)

This may be somewhat related to bug 96134, but that one deals with saving whole
emails, not attachments.  But maybe the dialog window is the same?

The ".exe" arises because the attachments will have been assigned the MIME type
"application/octet-stream" (probably assigned by a mail client which couldn't
tell what the file really was). This is usually used for applications, hence
Mozilla's addition of the default extension ".exe".

Yes... we suck.
