When a customer replies to the automated email response from a new comment being added, the email is sent to jira@getmoresystems.atlassian.net, which does not exist.
The replies also do not show in the tickets.
I've checked the email settings and the only active email address we have is support@getmoresystems.atlassian.net. When I try to add jira@getmoresystems.atlassian.net I get an error saying it's already in use.
