OK, consider the following scenario:

0) All the mailboxes except Trash may allocate 500MB.
Trash may allocate any percentage below 100% of 500MB.

1) One message arrives of the size 500MB, it get spooled into INBOX.

Now try to do anything with it.

OK, this is a worst-case scenario; the independed Trash quota must be 
larger than or equal to the maximum message size you accept.

Second, someone already pointed out that the user can use Trash as 
yet-another-folder, e.g. to store information. You effectively increased 
the quota of the user, or you lower the user's quota (in the view of the 
user) by reserving part of his quota for Trash.
Well, many people will point out that hard disk space is cheap today.

In my opinion, one user has one quota for all the message storred on the 
system. I used to empose file system quota, with the same effect that a 
full mailbox locks the users from deleting through Trash. :-(

Bye.
