Most recent E-mail systems, that are serviced in Korea, are supporting Hangul in many fields of E-mail(For example, contents, subject, attachment, etc.). However, these systems do not support Hangul in the address field of E-mail. In 2003, IDNA built the international standard in order to support multi-lingual besides the alphabetic character, a number, and '-'. So, Hangul cab be used in the domain part where is the right of '@' mark among the compositional element of the E-mail address. But, the local-part, where is the left of '@' mark, doesn't still support multi-lingual. So Hangul cannot be used in the local-part. In order to support multi-lingual including Hangul in the local-part, this paper designs and implements the E-mail system according to the EAI standardization research that it is progressed in IETF.
