To finish my unfinished thought there....

Check the users sieve scripts and your local anti-spam tools if any.  If 
messages are being completely lost, that will be the reason why.  The 
duplicate message suppression won't (usually) cause a message to become 
completely lost.  In the case that it does, it's NOT duplicate suppression 
at fault, its the clients MUA or MTA for disregarding the RFCs and 
generating duplicate message-ids.  Older Microsoft MAPI clients (Lookout, 
etc) are known for this bad behavior.
