Hello
I have been informed by a customer that they are not receiving email notifications from our Jira system.
They are the Reporter of the Issue raised.
A Test email from Jira was received by the user. I can't work out why as the Reporter they are not receiving emails when a comment update is made. Here's the results of the Notification Helper.

Hope you can help.
Obviously I can provide you with the actual email address of the user if you need to check anything being blocked.
Peter
