- I think it is high time that some form of standard return receipt were
- available in Internet mail. It's one of the few functional areas where the
- Internet lags behind practically ever proprietary mail system, and X.400 to
- boot.
-
- Suppose one were contemplating writing such an RFC (one is in fact
- contemplating exactly that :-)). What should it be? Bear in mind that it
- must be practical to implement and provide some useful amount of function.
-
- My initial leaning is to enshrine "Return-Receipt-To:" as a standard for
- successful delivery, since it has some utility and is also not going to go
- away anytime soon (rampant fantasies of sendmail haters aside :-)). But I
- would also suggest a "Read-Receipt-To:", to be generated by the MUA (and
- ONLY the MUA) when the message is actually read.
-
- Let me enumerate some of the objections I've heard to this type of feature,
- and rebut them:
-
- Delivery receipts:
-
- Objection 1. Since not every mail system implements it, it's meaningless.
- Failing to receive the receipt does not mean the message was not delivered.
- Rebuttal 1. While it is true that the negative is of questionable value,
- the positive does indeed mean something. And, in the scope of a local
- authority, it's quite possible to make the negative mean something, too.
-
- Objection 2. Where do you draw the line at what is "final" delivery? What
- about POP and POP-like systems?
- Rebuttal 2. Who cares? :-) You do at least know that the message was
- delivered to some maildrop. It's better than nothing.
-
- Objection 3. Bandwidth. Return receipts would eat the Internet alive.
- Rebuttal 3. The annoyance factor to the receipt-ee is high enough that I
- don't personally feel this is a problem.
-
- Read receipts:
-
- Objection 1. See above.
- Rebuttal 1. See above.
-
- Objection 2. See above, but replace '"final" delivery' with '"really"
- read'.
- Rebuttal 2. See above, but replace 'delivered to some maildrop' with
- 'examined by the user or some direct agent of the user'.
-
- Objection 3. See above.
- Rebuttal 3. See above.
-
- Objection 4. It's none of your business when or if I read my mail.
- Rebuttal 4. MUA's can provide you the option of suppressing read-receipts,
- if you're paranoid. This lessens the meaning of a negative, but again
- leaves the positive unsullied.
-
- Objection 5. A user-generated reply is the best return receipt.
- Rebuttal 5. True. But why not automate the process for the recipient's
- benefit? I would be perfectly happy if my MUA could acknowledge things for
- me, so I could then get around to them in my own good time without seeing
- repeated "Did you get my message?" queries.
-
- Objection 6. Various quibbles about exactly what the US Postal Service does
- or does not mean by or do with a return receipt, and various arguments
- about how they could or could not be implemented in the Internet.
- Rebuttal 6. Who cares? If we wanted to emulate the USPS exactly, we'd
- build a random mail misdirection system, and intentionally rude and stupid
- MTA's. (Comments about sendmail not invited :-).)
