Stop blog subscription emails to administrator?

Email notifications of new blog subscriptions (email subscriptions not RSS) are being sent to the administrator. The subscription dates are from 3 months ago so the notification isn't very useful. I haven't been able to locate any configuration settings to disable these subscription notifications so they aren't sent to administrators. Is there a setting for this? And why is it telling me about subscriptions from long ago?
