I have recently been added as admin to one of our Moodle sites (using Moodle 3.5) and am now the main admin. Since, the other admins receive notifications (e.g. on available Moodle updates) from Support services as well as from myself via the site. They have always received them from Support services, though now get the duplicate email from me. This is happening automatically.
How do I prevent this duplication?
