Apple Mail: winmail.dat
I have been receiving a few emails lately that contained an attachment called winmail.dat that could not be opened with any application that I had. After a bit of digging around I have found that these attachments are a wonderful (read idiotic) idea of Microsoft to attach files to emails from Microsoft Outlook/Exchange. In Apple Mail the attachment appears as a winmail.dat file that is of the mime type “application/ms-tnef”. Luckily Josh Jacob has made a program that allows you to extract the files out of this TNEF file. You can download TNEF's Enough from here or here.
