Options to manage Mail replies on closed Tickets
currently its possible to send Mail to closed tickets and they are processed in the same way like the ticket is open.
I think it is very helpful to add an option that if a mail comes for a closed ticket
a) an answer mail is sent with a customizable text like "This Ticket is closed; Please open a new one" or
b) a new Ticket should be created with reference to the closed ticket.
c) leave default behaviour active
It would be perfect, if the configuration could be made at project level.
I think this Features is an "normal" Feature compared to other Project Management Tools.
