Someone already asked something like that some day ago.

You can write a postfix policy that will return a 45x or 55x code when
the recipient mailbox is full.
This can be easily  added to the smtpd_recipient_restrictions postfix option
Your policy script must take care of aliases too and to resolve the
recipient mailbox
by querying  the ldap DB and finally check the quota usage of the
recipient mailbox
before to return the SMTP code.
