JIRA is not only able to send mails to users, but also to poll and process e-mails, and it can create issues or add comments to the existing issues. When set up correctly, this can be a powerful way to let your users interact with JIRA.
In this recipe, we will set up JIRA to poll incoming mails so that it can create new issues and add comments to the existing issues. This is useful in a help desk scenario where customers can write e-mails to the company's support e-mail address and let JIRA automatically create issues from them.
