We recently had an issue, where the jira-users group has been made a member of the Users role in one of the projects, and having forgotten that, one of the administrators has changed the notification scheme of that project to send email to member of the Users role when a new issue is created.
This resulted in two emails being sent out to 8000+ users.
Is there a way to prevent this in the future? Since we have quite a few users, some of them are project administrators of their own projects.
Can we either prevent JIRA from sending out an excessive amount of email (let's say over 1000) triggered by one single event? Or can we prevent users from adding the jira-users group to any role in the projects? Or is there any other way we could prevent this?
