No it won't.  This is because the quotas are only kept on the backend, 
so for remote mailboxes, only its existence and ACL are checked.

Having a globally accessible quota database would solve this (as well as 
removing the restriction of having to have all mailboxes under a 
quotaroot on the same backend) or smmapd could send RCPT TO to the 
correct backend to do the check.
