We have certain tickets that Jira won't send email notifications for. It's not limited to a specific user. A user that turns in tickets frequently has noticed that he didn't get email notifications for certain ones. When we did a message trace Jira had not sent one. We have been researching for a few weeks now and can't find a common denominator. Co-worker turned in a test ticket. He didn't get an email notification for it. Added me to it, I didn't receive a notification either. However, we receive notifications for other tickets. Suggestions for other things to test or possible solutions?
