Are they truely duplicates?  Compare the Message-IDs of the two 
messages.  If they *are* identical, then either duplicate delivery 
suppression is disabled, duplicate delivery supression is broken for 
some reason (corrupt deliver.db?), or the messages we're not inserted 
into the mailbox via LMTP.
