We are working with a customer that's using there own Jira Board. So for issues we must always log in to there environment. I have now add a rule on my mail(on that environment) that when a issue is assigned to me it automatically send it also to my personal gmail account. Now when the mail comes in with the issue it must automatically create a ticket in Jira ServiceDesk. And when there are updates in the issue it must not create a ticket, only the first time it comes in.
