The duplicate checker looks for duplicate message ids (the first field 
below) and discards messages that contain the same message-id.  The biggest 
reason for this is a large number of IMAP clients did (do) use message-id 
to find and retrieve messages, also the message-id header is required to be 
unique.  This is why your /etc/cyrus.conf file has a line similar to 
'delprune        cmd="/usr/sbin/ctl_deliver -E 3" at=0401' occuring inside 
of it, this purges the duplicates database of anything more than three days 
old for this example at 4:01AM local time.
