Actually, no. Currently mail is delivered by LMTP along the lines of 
user+flag at domain.com is appending to Pending. We are having issues with 
corrupt mail stores, and previously deleted Pending folders, and want to 
implement a less noisy way of dealing with this (basically Pending 
handles possible spam, for approval by user - if this folder doesn't 
exist, this gets dumped into inbox, and users complain about less than 
optimal spam filtering. We just want to do a 'reject'.
