One of the six fundamental attributes of information that we protect is integrity, one aspect of which is consistency with the originally stored data. When someone goes to the trouble of producing an elegantly formatted memorandum or other document and sends it out to recipients, everyone would like to preserve data integrity by seeing the same appearance on all the systems sharing that document.Unfortunately, sending formatted messages as e-mail messages (as distinct from attachments) does not guarantee preservation of the exact appearance of the source material.Attractive, well-formatted e-mail messages with boldface, italics, different point sizes and the like usually get transmitted as HTML to recipients' mailboxes, where most people\u2019s e-mail clients (Eudora, Netscape, Outlook and so on) allow the funny-looking code to be reconstituted into something similar to the original.I say \u201csimilar\u201d rather than \u201cexactly like\u201d because HTML does not necessarily control the final appearance of text on a recipient's system. The codes refer to types, not exact matches, of fonts; thus a sender might want to use, say, 24-point Arial as a Heading 1 display but a particular recipient might have defined Heading 1 as, say, Times Roman 14 point. A two-page original document may appear to be a three-page document to one recipient and a one-page document to another recipient.More significantly, though, many people turn off HTML e-mail for security reasons. All such formatted e-mail gets converted automatically into plain ASCII text. The fragment of message below (demarcated by the > and < symbols) is in plain text as I received it:>Note: The on-line course evaluation system may be used from room, lab and home ? anywhere Internet access is available.Overview: . . . .
