- I'm not sure that an exact mapping of the way the U.S. Postal system does
- things is necessarily a good thing. As you say, the postal system return
- receipt is not what I was describing. I think that a reasonable analogy
- would be the the postal return receipt would correspond to a MTA delivery
- report. A user agent return receipt in the USPS world would be more like
- the postman coming into your home or business, watching you open you mail,
- and then writing a report back to the sender indicating it had been opened.

- This is an interesting option - but one that I don't believe would be
- necessary for most applications. Perhaps if we were to come up with a
- mechanism that would work with and without digital signitures?

-
- It should also be acceptable if the remote UA were to do nothing with
- the request. The key here is that it is a "request".
