FromUserName sender account (an OpenID)

MsgId message id, 64-bit integer [/color]
This means that the developer accepts the xml data packet sent from the server POST and sends it back to the server in the same xml data format after processing.
When sending the data back to the server, the ToUserName and FromUserName remain unchanged? What is the impact of changing Content? is it sent to the sender's account?
