A Redmine plugin to suppress email notifications (at will) when updating issues.
Works fine with Redmine 2.0 - 2.4, whereas the original repo doesn’t (after commit f6cc13725c)
For Redmine versions prior to 2.x, check out the pre-2.x branch.
Simply clone the git repo under plugins/ and restart the webserver.
Then go to Administration > Roles and permissions and enable ‘Suppress mail notifications’ permission for roles that need to be able to do that (typical Manager and/or Developer.)
