I have a Prime 3.1.6 setup that I have tried to reset alarm email notifications to just my address. When an alert is fired (rebooted AP etc) the email is still going to 2 other people.
I've tried resetting all of the alerts to default (my address):
Admin - System - Mail and Notification - Mail Server configuration; Apply recipient list to all existing alarm email notifications.
Still sending to 2 other recipients. Where else would this be configured? I can't even find the other 2 email addresses configured within the system. When I check the link "Configure email notification for individual alarm categories." all of the alert categories only show my address.
