Network Diagram

According to the Figure, once users’ network link mail server is back to normal, the E-mails sent to users’ domain will be forward to users’ mail server directly. In case when users’ network link or mail server cannot receive E-mails sent to users’ domain, it will also be sent to the Mail Buffer automatically. The Mail Buffer will then keep users’ E-mails until users’ network link or mail server is back to the normal stage to forward these E-mails back to users’ mail server.
