I have a requirement wherein whenever any exteranl-user sends mail to our mailbox in jira that creates issue but we have to add that user in jira manually. We would like to get them added to jira automatically in such a way that they are denied jira-users privilege but just exist as user in jira whoc can comment to that issue and our comments send mails to theuir mail-ids without actually adding them to jira so that our jira license count is intact.
Also if this is possible with JEMH can somebody list the steps that would need to be configured in JEMH as per above requirement.
