Q: For customer can I set it to send mail (autoresponder) only at ticket opening and only at closing ticket?A: You would need to select to always "Do not email reply" when answering a customer since per default every reply is sent to a customer. Alternatively you could modify the source code to achieve this. This question was already discussed in another thread, but unfortunately can't find it currently.Q: And at closing ticket can transmit history of his ticket?A: You would need to copy all responses from agents and all messages from customer to the last response when you close a ticket.
