I have set an email address to receive email notification once a new ticket is created. The email is set in Project Settings > Notifications > Edit Notifications > Default Notifications, but no email is received on ticket creation, the user who created the ticket receives the email notification.
What could be wrong or not configured ?
Yeah.. Beside project membership I asked if the role you gave this user has all the necessary permissions, like browse project permission. Does this role grants him this permission?
And again I asked if any security level is applied to the newly created issues and the role which this user has is included in this role.
This user is from our own Team, and not the end-client. The end client is the one creating the ticketing and receiving email notifications.
The user maintenance is a mail box distribution list, does not have any special permissions applied to it, all of it is default, the role applied to it is of Customer Service Team. The maintenance user is not an actual user that logs into JIRA.
So there's your problem.
In the first case, as mentioned earlier, your maintenance user does not have the browse project permission. This mean that he will never receive any email notification for the issue creation event for as long as the browse project permission is not been granted to him.
The second case, your user, will not receive any notification because he is not a reporter, current assignee or watcher.
For the latter case, when you run the notification helper, had you already included your email in the notification scheme?
Instead of adding yourself with a single email list, since that option has its restriction as you can see in the image above, I would suggest to create a specific role and grant this additional role to your self (dont remove yourself from admin). And add this role on the issue created notification. That should do the trick for your email address.
