What is X400?
X.400 is a series of ITU-T standards defining a message handling system (MHS) for electronic mail. It was widely adopted in the 1980s and early 1990s, particularly in large organizations and government sectors, before the rise of the Internet and SMTP-based email. X.400 specifies protocols for message transfer between different messaging systems and defines various aspects of message structure, addressing, and security.
