Optional email headers
Now 8 years later, this feature #5643 is in some cases seen by vulnerability that exposes unnecessary information.
It would be preferable to have a checkbox to completely turn-off Redmine headers.
This should probably be a patch I can create it later some time if I catch some time.

What I got complained about is that it exposes active directory user (X-Redmine-Sender).
