- I would tend to agree with your leaning, but several SMTP compatible
- mail packages already implement "Return-Receipt-To:" as a read
- receipt (Control Data's ASCENT*Mail is one of these and is widely
- used in the U.S. Air Force). I had the pleasure of hacking "elm"
- to recognize and implement this header for an Air Force customer
- who demanded this capability and desired compatibility with
- existing systems.
-
- My recommendation on this subject however, would not be to
- try to formalize the "Return-Receipt-To:" header (or create
- a Read-Receipt-Header), but instead to attempt to take advantages
- of MIME, which is now gaining rapid popularity. By using MIME's
- content type/subtype classifications similar to "message/external-body",
- one could implement read receipts at the MUA level as you suggested,
- but probably with much greater ease. A good example of how
- this could be done is the MIME compliant messages sent out by
- the IETF announcing new/proposed RFC's. When these messages are
- read with a MIME compliant reader, the user is given the opportunity
- to automatically send a request to a mail server.
-
- Although metamail's "showexternal" script is not ideally suited
- to read receipts, perhaps a new MIME subcontent type definition
- (and accompanying metamail script for MIME readers using metamail) i
- would allow the easiest and most elegant implementation of read receipts.
