We proposed secure e-mail system using HS-DRTtechnology and evaluated transmission intervals forsubsequent fragmented-messages. By implementingHS-DRT system in secure e-mail system, originatingmailer can send e-mails automatically with the differentgeographically routes by using different mail accountssimultaneously, leading an innovative secure e-mailsystem. It is found out that fragmented-messages needto be sent with the transmission interval appropriate toeach mail provider. In the future, we will implementmultimedia e-mail including audio, picture and realtimevideo.
