- Delivery acknowledgements and read acknowledgements are, as has been
- exhibited, a very emotional issue. They question generates a lot of heat but
- very little light. Extreme views proliferate, with very little moderation in
- between.
-
- One such extreme view -- which I subscribe to -- is that the privacy violation
- of this sort of function is of greater concern than the benefits. I do not
- necessarily want to acknowledge certain messages, much less tell someone if
- and when I read it. One frightening thought is the prospect of service of
- legal process through e-mail. The possibility also exists of covert channels;
- remember, you can get more information out of an acknowledgement than just the
- fact that the message was received.
-
- Delivery acknowledgements aren't as serious in their violation of privacy, but
- they don't verify that the user read the message. A lot can happen to a
- message between the time that the MTA delivers it and it is displayed on a
- screen. There is a privacy violation question as well; it makes it more
- difficult for a user to ignore mail and pretend it never reached him.
-
- My personal viewpoint is that the only acceptable solution is a client-based
- read acknowledgement, *under the control of the user*. That is, a slightly
- more automated mechanism than the message with a first line saying `please
- acknowledge receipt immediately.' Some cookie in the message triggers this in
- the client, and the user is asked whether or not he wants an acknowledgement
- sent.
-
- Of course, what an organization does in its INTERNAL mail infrastructure is
- its own business, and it is reasonable for e-mail implementors to provide this
- facility for internal usage. External usage is another matter. As
- frustrating as it may be for Joe Mooch at Foobar Corporation not to know if
- Nancy Nebbish at Garply Industries has received his message, ultimately, it is
- up to Nancy (and Garply) to decide if an acknowledgement -- or a reply --
- should be made, and software should not subvert this.
