We have setup an Email handler for our JIRA Service desk.
Sometimes emails are sent by customers whose email is not part of the allowed list of emails (not created as customers within JIRA service desk).
We have observed that emails do not reach the service desk (confirmed from the logs)
However, these delivery failures are not notified to the actual senders. This is a problem because the sender still thinks a service desk ticket has been raised.
Is there a way to override this behavior. Is it a default setting on the mail server that handles this on Atlassian.
Does anyone have any ideas on how to work-around this issue?
Thanks.
