I can't get the e-mail comment functionality to work. When I comment on a issue in YouTrack, the user that reported that issue will get an email. So far, so good.
The user laters tries to add a comment by just answering the email.
Instead of adding a comment on the issue (in this case TF-527), YouTrack adds a whole new Issue for this.
Is it possible to get YouTrack to add responses as comment? I have read something about it here http://www.jetbrains.com/youtrack/features/issue_tracking.html
but I can't find any configuration for it. Is there any one who can give me a hint on where to find information?
