When Remoba products are configured to use security, no user data is transmitted until a secure connection has been established. Remoba uses the SSL (Secure Sockets Layer) protocol to transmit data securely. SSL is the industry standard for transmitting sensitive information, like credit card numbers, over the Internet. SSL is a protocol that provides server authentication, data encryption and message integrity. With SSL security implemented, communications are transmitted in encrypted form between the client software on phone and server. Only once the SSL connection has been established are the username and password transmitted to the server. Once the user has logged in, data can be securely transferred. Remoba supports 128 bit SSL encryption.

Small companies may choose a configuration where Remoba operates with a direct, user-defined IMAP/POP3 port connection through their firewall to Email. Similarly, corporate directory authentication and lookup is processed through a user-defined LDAP port. See Figure 2.

Medium to large companies may choose a configuration where Email traffic and data requests redirect to a proxy server. Connection to the proxy server is through user-defined IMAP/POP3 and LDAP ports and the enterprise can choose which ports connect from the proxy server to the corporate servers. See Figure 2.

Large, national companies may choose a configuration where Email traffice and data requests rediect to a proxy server that is connected to several, distributed servers. In this configuration, RemoMail connects to the proxy server via user-defined IMAP/POP3 ports and the enterprise chooses which ports connect from the proxy server to the Email servers. Additionally, corporate directory authentication and lookup can be handled from the proxy server directly to the correct Email server for global Address Book lookup. See Figure 2.
