Exchange 2010 Quotas and Rejected Messages

Here's my scenario.  We have quotas set on all of our mailboxes in our environment, and when a user passes the limit it rejects all messages destined for that mailbox.  The problem is these messages are not being retained at all and are just being dropped.  Is there any way to queue these up so that once the mailbox is under the quota limit they can be redelivered?
