Does the user have files stored in their account?
Do they have files attached to their messages in their INBOX?
You already stated you checked the user's DELETED folder. Do they have any other folders, or sub-folders, setup?
Do they have a SPAM folder?
Do they have mailbox folders for external accounts which are downloading mail from those sources and storing on the SmarterMail server?
Everything in the mailboxes and the LOCAL files is counted in the user's storage
