OpenFire Smack message receipt settings, handling swap issues

In the network instability, openfire prone to swap situations, because when the client dropped the line, OpenFire can not immediately know that the client has been disconnected, as to how long it takes to find the client disconnection, and the server-side set idle Connections time. The default is 360 seconds.

To solve the swap problem, the XMPP protocol supports message receipts, which simply sets the request receipt when the client sends a message, and the server does not need to set it up.
