One of the deficiences of the current FTP mail protocol is that it makes no provision for the explicit specification of such header information as author, title, and date.
Many systems send that information, but each in a different format.
One fairly serious result of this lack of standardization is that it's next to impossible for a system or user program to intelligently process incoming mail. Y'all be here. No attempt has been made to legislate the format of , except to exclude spaces from it. The time has no internal punctuation. No provision is made for multiple authors.
