I have configured JEMH to do the various things needed to create a new issue on receipt of an email from a non-jira user, store their email and so on. That is all fine.
The problem is that if I then send an email from the system to the user that raised the issue, when they reply to that email we get another issue create an opposed to an update/comment on the original issue. I'm pretty sure I've configured something wrong, or rather haven't configured something that I should have, but I'm stumped to know what it is.
Thanks.
