The quote does not change because the mail is not deleted. It's only  
marked as deleted (T flag). Once the folder is expunged (that's how  
IMAP call it; your webmail mail give a different name for this action)  
all mails flagged as deleted are actually deleted and space is released.

The easiest solution would be to use a Trash folder also for this  
domain. Or, if you do not want that, you'll have to instruct your  
users to expunge their folders when they want to claim space. I  
believe there is also a plugin that should do automatic expunging, but  
I don't known when it's triggered.
