Redmine Silencer 2
A Redmine plugin to suppress email notifications (at will) when updating issues.
Especially useful for silent mass-updates when you don't want to spam all the project participants with your minor update.
This is a fork of the 'Redmine Silencer' plugin with additional contributions from github users @commandprompt and @tofi86 (CTO @paginagmbh)
This plugin is listed in the Redmine plugin directory
Works fine with Redmine 2.0 - 2.6 and Redmine 3.x, whereas the original repo doesn't (after commit f6cc13725c)
For Redmine versions prior to 2.x, check out the pre-2.x branch.
For Redmine versions prior to 2.4, check out the pre-2.4 branch.
For Redmine versions 2.4.x - 3.x use the master branch.
Simply clone the git repo under plugins/ in your redmine directory 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 (typically Manager and/or Developer.)
You can also enable the 'Suppress mail notifications' checkbox by default in Administration > Plugins > Configure for the 'redmine_silencer' plugin.
