  Sorry, I thought I listed that information in the bug report.
  Of course, all clients are effected as this error is generated on the server.

+ I believe I have found the problem.
+ My manager sends mail from Pegasus Mail for Win32 (v3.12c), and after looking at
+ some message sources it seems like Pegasus doesn't handle mime types very well.
+ (See example below.)
+ It seems that Pegasus likes to set the mime-type for MSWord, acrobat, and other
+ documents as "Application/Octet-stream", so when the attachment shows up on
+ message.php it is not associated with the correct type of viewer.
+ I don't know how many other mailers are guilty of this, but maybe you could add
+ code to check filename extensions if the mime-type is not defined, or not
+ well-defined.
+ 
+ For instance (some lines removed):
