The transmission details are specified by the Simple Mail Transfer Protocol (SMTP).

X.400 is a suite of ITU-T recommendations that define the ITU-T Message Handling System (MHS).. At one time, the designers of X.400 were expecting it to be the predominant form of email, but this role has been taken by the SMTP-based Internet e-mail. [1]
