Re: [TUHS] who invented the email attachment?

However, the "attachment" as a concept has more to do with "presentation" of the email message: the "attached" part is always, even in MIME messages, part of the body of the RFC822 message. In that sense, it does not matter whether it is inline source code, inline 'shar'-ed files, inline UUencoded, or inline MIME. What makes it an "attachment", is the MUA ability to present it and to manage it as a distinct part of the email message, different from the headers and different from the "textual" body. So, according to that, the inventor of the "attachment" was whoever wrote the first MUA capable of presenting and managing certain body parts of a RFC822 message as such separate entity. The "attachment", therefore, would be a user interface design decision, undoubtedly facilitated by some underlying technology such as uuencode which defined a boundary to mark the 'begin' and 'end' of the inlined non-textual data. But I have been wrong before - many times. -- Josh Good
