We have a lot of issues/incidents created by email (from users outside our company). We have set up Mail handler to Create Issues or Comments from support mail server, but are receiving the following message when a user sends an email to the email address:
[atlassian.mail.incoming.mailfetcherservice] The message has been rejected: Reporter (xxxxx) does not have permission to create an issue. Message rejected.
Please advise on how to change permissions.
