JIRA won't send out an automated email to anyone that does not actually have an account in JIRA. That is by design to prevent turning JIRA into an email spamming machine.
By default in JIRA, only the reporter (the sender in the from address) would be notified of this issue's creation, along with the issues current assignee, and the watchers of this issue. JIRA only allows a single reporter, and a single assignee for any single issue. The watchers field could be helpful here, but there is not a means for JIRA to automatically add all those email addresses as watchers to that issue. The JIRA mail handler just is not natively equipped to handle that kind of processing.
Watchers first need to have an account in the JIRA instance as well. So that is a hurdle here. Perhaps there is a plugin to JIRA that might be able to provide this functionality.
Alternative to this could be the use of the JIRA Service Desk add-on. This add-on has a different way of handling mail in JIRA and in turn it can automatically be made to add addresses in the CC field to a special field called "Requested participants", this field can have multiple values and in turn can be used more for this kind of case creation notification.
