Ooops...


The code above contains a mistake. It will prefix the subject only for
messages that DO have the X-No-Archive: header. What you want in the
if test is 

     if msg.get('x-no-archive', None) <> None:
         return

to skip the prefix if the header is not None. Those double negatives
will get you every time. ;-)
