In JIRA I am a member of service-desk-agents but I don't receive an email when a new Service Desk Issue is created.
The notification helper says I should receive a notification.
Also related is that if I trigger an email for a customer I won't receive an email (based on my settings). The email says it is from me but it is actually from JIRA's automailer. When the customer replies to that email (not in JIRA) I won't receive the email and there will be no comment on the issue.
