New listing email being sent to all admins

Hi Folks,

System emails that are meant to go to the admin are being sent to all three admins. I only want them to go to one address – mine. Can I change this?

At the bottom of the Email Management page under “Send admin emails the following user roles”, I have Super Admin checked. So on a related note I’m wondering where the other two options (which are Site Manager and Employee) are assigned to users? I’ve never seen these settings anywhere.
