problem with how errors are handled by cyrus

[VALOIS, Pascal]

hello, 
        
        i'm sorry if what i asked is a well know problem, but i can't
        seems to
        get a valid answer digging the web.
        
        my problem is the following : 
        
        when a mail has multiple "To" recipients, and one of them is
        overquota,
        the sender get a temporary failure mail telling that all the
        recipients
        are in temporary failure.
        
        is that due to someting ill configured ? 
        
        do you know how to only notify about who is really over quota ? 
        
        thx for reading, hope for answers
