Mapping between X.400(1984/1988) and Mail-11 (DECnet mail)

Status of this Memo This memo defines an Experimental Protocol for the Internet community. Discussion and suggestions for improvement are requested. Please refer to the current edition of the "IAB Official Protocol Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract This document describes a set of mappings which will enable inter working between systems operating the CCITT X.400 (1984 / 1988) Recommendations on Message Handling Systems, and systems running the Mail-11 (also known as DECnet mail) protocol. The specifications are valid within DECnet Phase IV addressing and routing scheme. The complete scenario of X.400 / RFC822 / Mail-11 is also considered, in order to cover the possible complex cases arising in multiple gateway translations. This document covers mainly the O/R address to DECnet from/to address mapping (and vice versa); other mappings are based on RFC 1327 and its eventual future updates. Mail-11, also known as DECnet mail and often improperly referred as VMSmail, is the proprietary protocol implemented by Digital Equipment Corporation (DEC) to establish a real-time text messaging system Allocchio [Page 1]
