postfix, user quota, bounce email - is it possible

[awgan]

There is a simple question.
Is it possible to configure postfix in the way that it wil bounce emails when user mailbox is over quota ? I've been searching quite lot and can't find any answers/sample config.

Thanks for any replay

Sure, use the mailbox_size_limit = <limit in bytes> directive in /etc/postfix/main.cf.

Check out http://www.postfix.org/postconf.5.html for further details.
