Redmine Exception Handler Plugin

It’s that time again….. yes, I’m Open Sourcing another Redmine plugin. This time it’s the Redmine Exception Handler plugin. This plugin will allow Redmine to send emails whenever an exception or error occurs. I created this plugin because I kept hearing about bugs but I having a hard time reproducing them. This plugin uses the exception_notification Rails plugin created by Jamis Buck.


  • Allows configuration of recipients, sender address, and subject line without restarting the web server
  • Email contains a stack trace and full environment dump that can be used to reproduce the issue
  • Test controller to test the system settings
