Currently only the Server Dialback method is being used for authenticating the remote server. Once the remote server has been authenticated incoming packets will be processed by this server. It is also possible for remote servers to authenticate more domains once the session has been established. For optimization reasons the existing connection is used between the servers. Therefore, the incoming server session holds the list of authenticated domains which are allowed to send packets to this server.
Using the Server Dialback method it is possible that this server may also act as the Authoritative Server. This implies that an incoming connection will be established with this server for authenticating a domain. This incoming connection will only last for a brief moment and after the domain has been authenticated the connection will be closed and no session will exist. @author Gaston Dombiak
