Messages spooled into a mailbox may be immutable, but the same message may 
take different paths to arrive one particular mailbox, say, through 
different mailing lists or recipients, remailed or forwarded. I would 
_not_ like to see these duplicates discarded. However, it makes no sense 
to me, if the message of one delivery attempt is spooled twice into the 
same folder. (Actually I can imaging just one need to spool it into two 
boxes, hence, it could issue an overridable warning.)
