Not sure why rules are limited to emailing Groups, Agents, certain requestors. It would be great to be able to put in one or many disparate email addresses on an ad-hoc basis.
For example:
If I have a mail catch doing something after hours, it may go out to a call service. The call service may not require access to tickets (so they aren't an agent).
Or simply that you want to forward all emails that come in to a resource mailbox somewhere.
