I would like to keep the original email sender address in JIRA, when I receive an email, which is handled by JIRA. Currently JIRA replaces the sender with the JIRA Master Admin address. I remember, that we had setup the handler to keep the original email address on another company I administerd JIRA, but don't remember how we managed to do this.
Reason why I want that is, that I would like that the sender is being informed automatically on the updates (adding comments, status changes etc.) wheneverr that is done.
