For anyone who wants to know how to do this:Within include/class.ticket.php Edit the query on line 1138 and set status_id to the corresponding status on the database table (ost_ticket_status) for me it was 6. db_query('UPDATE '.TICKET_TABLE.' SET isanswered=0, status_id=6, lastmessage=NOW() WHERE ticket_id='.db_input($this->getId()));Now every time a client emails a response the status updates.
