Case "closed" create new ticket/ change status of case when reply email comes in

[joy11]

It would be a great feature to have cases that are closed not be able to accept new emails, but instead, have them create a new case so that they can be merged or if that is not feasible, to automatically update the case from closed to either new or pending status when a new email is received. From case management standpoint, this would ensure that no emails or responses slip through the cracks. We don't go back and check closed cases and there is limited access to the actual group email account outside the CRM used to create cases.
