DTN protocol can overcome network problems such as intermittent connectivity, long or variable delay, asymmetric data rates, and high error rates. TCP/IP protocol, a common network protocol currently used for the internet, cannot handle these problems. By using postfix and DTN2, we can build a DTN-based e-mail server that is capable of sending and receiving e-mails even the server is not continuously connected to a network. This also requires a new method to send and receive e-mails. Postfix is used for managing and processing e-mail users. DTN2 is used for processing e-mails into bundles and bundles into e-mails based on DTN protocol. This requires programs that integrate the postfix e-mail system with DTN2, implemented using bash shell and awk, for sending and receiving e-mail. The email system has been tested in the real condition using trains. The results show that the DTN based email system is working properly.
