Hi, I've run into trouble setting up the configuration for OSTicket (1.9.12) to not send email to User.I use OSTicket for internal purpose only. We got about 4 Agents and 10 Users(User here is company employee).When creating new ticket, i still add user as customer (Ticket owner), then i disable the autoresponder for sending email to customer and it works fine.Then if i add recipients (Company Employee) and post some replies, there's no email sent to Customer, which is good.But when the User(Company Employee) come and post reply, there will be email sent to Ticket owner, that's not good. So i decided to disable the "Participants: Send new activity notice ". But with this configuration, another User (Employee) will have no chance to receive email telling them that another User has post reply.I try to take a look at the code and i find out that the send email function is located at include/class.ticket.php in postMessage function. And i don't know how to exclude the Ticket owner from the participant list so that he can't receive any further email.Please help me out, thank you.
