[Dovecot] dovecot quota feature request

[Shing]

Hi all,
I'm going to implement before queue quota check with postfix to prevent 
bounce mail, the quota information is stored into mysql using dovecot 
quotadict, it would be nice that dovecot can have an option to switch 
the quota check with (used space < quota) instead of (used space+mail 
size < quota), so that i can write a simple sql statement to 
check_recipient_access to reject those mail, thanks.
