If it's a PDF content type, you've got a problem with associating the right program with the file. If it's octet-stream, the mail author stuffed it up, and you're left with manually saving the file and opening it with something else. Octet-stream is a generic content type for ANY type of binary file. It simply means this file is some sort of binary. You can't associate a program with that type, because it could be used for anything. You could try associating it with a PDF viewer, then you'd get stuck, again, when someone sent you a JPEG, or document, as octet-stream, later on. If you use Gnome, you could try associating it with gnome-open, and hope that it can handle the file type, itself, as a middle man. This is a common problem, and it'd be helpful if mail programs let you set up a list of open-with program handlers for unidentified binary files (e.g. open with evince, open with eog, open with openoffice.org) that would pop-up when you clicked on such attachments, letting you choose the most likely one. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
