I had a case of INBOX corruption today.  I have not yet been able 
to reproduce it consistently with a small example, but here's what 
happened, in case a bell rings somewhere:

1) Starting point is an INBOX with approx. 60 messages, many with attachments 
2) I use mouse-3 to save an MS Word attachment from one of the messages to a file
   (NOTE: the attachment had already been saved, but the button appears 
    as usual, and I did not notice this)
3) I get the following error message: 

      MIME part missing header/body separator line

4) Subsequent scrolling in the folder (n, p) causes strange display 
   in Presentation buffer: visible X-vm headers, etc
5) Since something is hosed, I decide to press q in order to start over 
6) Since I had already edited INBOX, vm saves the buffer to disk 
7) I quit emacs, restart, restart VM
8) INBOX is now only 30 messages!  
9) File sizes confirm that VM saved an INBOX which was much shorter 
   than it should be

I was saved by the backup file, so I lost nothing important, but...
