If you mean notifying the recipient, then it is possible as far as I know..
You can create a quarantine report task, which will inform the users that they have quarantined emails..
it's also possible to activate a quarantine web console, which allow the end users to view a list of currently quarantined items, they can only release spam emails, other emails which has been blocked per rule will need an admin to be released
