Even though in an offline environment, user also able to read, write and send email as if he or she is in an online environment. This offline email system will allow the email flow through the offline environment to the online environment and vice versa. The most important part of this offline email system is an implementation of email database synchronization between offline mail server and infomediary device and between online mail server and infomediary device. Another part is an implementation of offline and online email system consist of mail server and mail client for both sides. This offline email system will be using operating system Windows XP 32bit, wireless local area network, and internet connection 1MB/s TMnet Streamyx Dynamic IP with the conjunction of Uniform Server for personal home server. This offline email system consists of offline mail client, offline mail server, database synchronization at offline server, infomediary device, online mail client, online mail server and database synchronization at online server.
