You can open an attachment (document/graphic/audio etc.) file by clicking it, 
however, what that means is that the file attachment is opened as a document 
for a specific application like xmms for mp3 files, or a graphic-file viewer 
for pictures. These associations are already pre-configured in most systems.

However, the key point being that the files don't need 'execute' permission to 
be viewed or heard ... since the application that the file is associated with 
is executable... And that's ok.... 

In the case of Windows, there is another major problem.. which is by default 
an option called 'auto-hide known extensions' is enabled ... which means if a 
file attachment actually ends with .EXE or .PIF extension but the filename is 
'filename.jpg.exe' then the user only sees an attachment called 
'something.jpg' misleading the user to feel that the attachment is not an 
executable but a jpg.
