Have you looked at the Virtual Trash option?  With Virtual Trash enabled, 
IMP follows the usual IMAP conventions of marking messages as deleted 
instead of moving them to a separate Trash folder.  But, it also takes all 
messages that are marked as deleted and hides them from the end user.  You 
will see a Virtual Folder named Virtual Trash as well.

Using Virtual Trash also plays nicely if you have mailbox quotas. 
Sometimes, if a user is close to their quota it is not possible to move 
(really, copy + delete) a message to their Trash folder.  With Virtual 
Trash, there is no move, so no quota limit is exceeded.
