Notifications to author of subscription not happening

I have the settings configured such that an author should be notified when someone subscribes to their blogs.

Unfortunately this is not happening...an email is sent to the subscriber confirming that they have subscribed, but the author does not receive a notification.


Also can an author manage subscriptions to their posts. For example, if a blogger gets subscribed to by someone they don't want to subscribe, can they block the subscription?

I do see where an admin can delete a subscriptionunder "Subscriptions" in the back end, but nothing from the front end. Perhaps it's in the notification email mentioned above (which isn't being sent, or so it seems.)
Thanks,
Andrew
