XMessage-Id: <MDC-DLS-7W9CS@OFFICE-1> XComment: Dave -- this is the body of the message I previously 'sent' to you via X Xa Journal. X XI might suggest re-wording the para on Author -- my associates might object to X'strange' -- something like: X X This is used to credit the original author, or to give credit on article X excerpts (from Newspapers, magazines, books, etc). X XOne field which I forgot is: X X Length: This is computed when the message is sent and gives the recipients X an estimate of the number of pages in the document. X X Example: X X Length: 6 pages [estimate] X XAccess: X X Used to declare whether a Journal item should be Public or Private (to those X that are on the distribution list or Extended Access list) X X Example: X X Access: Unrestricted X XAcknowledge-Delivery: X X Used to request the system mailer send back a message when it has X successfully delivered the item. X X Example: X X Acknowledge-Delivery: Requested X XAcknowledge-Receipt: X X Used to to ask the recipient to acknowledge receipt of the message. X X Example: X X Acknowledge-Receipt: Requested X XAddendum-To: X X A pointer to a previously submitted Journal item. X X Example: X X Addendum-To: <ASD,1234,> X XDelivery-Timing: X X Used by the sender to indicate when the message should be submitted to the X mailer. X X Examples: X X Rush: - immediate X X Soon: - as soon as possible X X Defer: - overnight X X Start-Delivery: DATE TIME X X Stop-Delivery: DATE TIME (if not yet delivered) X XDisposition-Code: X X Used by the system to group Journal items into one of several classes for X eventual archive to tape and as an indicator of how long the archive tapes X should be retained. X X Example: X X Disposition-Code: Temporary (2 years) X XExtended-access: X X Used with private Journal items to allow access by other than those on the X distribution list. X X Example: X X Extended-access: ASD.MDC X XLocation: X X Used to submit the message to the Journal. The adressees receive a short X citation with other header fields and a "Location:" field pointing to a file X in an electronic library. X X Example: X X Location: <MDC,1234,> X XPart-Of: X X A pointer to a previously submitted Journal item. X X Example: X X Part-Of: <MDC,1234,> X XRoute-To: X X Used to send a message "in-turn" to addressees in the "To:" field -- as X opposed to the broadcast method of delivery where everyone gets the message X "simultaneously". Any addresses in the "Cc:" field receive a copy of the X message each time it is passed from one adressee to the next in the "To:" X field. X X Example: X X Routed-to: {addresses in To field} X XSigned: X X Created when the user employs the Sign command; used to electronically sign X a message. It affixes a signature-block to a message. A "Verify Signature" X command is available to recipients that lets them find out if anyone has X changed the body of the message since the message was signed. X X Example: X X SIGNED X X Duane L. Stone X App. Dev. Mgr. X XSupersedes: X X A pointer to a previously submitted Journal item.
