Content-Disposition is pretty much useless when it comes to "attachments".

Because if you are talking about "attachments" as presented by a mail  
user agent... there is not objective standard to what an attachment  
is.  This has been discussed on this list previously (I believe I also  
made a somewhat lengthy post on this topic on the dovecot list in the  
past also.)  MIME messages can contain multiple "parts", but "parts"  
!= "attachments", if attachments is thought of as a discrete file.

Whatever an "attachment" is, it is a determination made by the  
application.  You can peruse IMP for example code on how we use the  
data provided by the MIME object to make our determination.
