[imp] Re: IMP 3.1 & Return Receipt or Delivery Notification

[Mark]

You are correct. The mail server (MTA) provides the delivery receipt.
Most MTAs have settings to either answer or reject delivery receipt
requests. Some also have the ability to strip off read receipt
requests, so that the end users never even get the read receipt
request. 

And yes, the mail reader (MUA) provides the read receipt. There are
web-based mail applications that have a pop-up when there is a read
request asking of you want to send it. To me it's a "nice to have"
rather than a requirement. What I haven't seen (but haven't looked
for) is the ability to accept or reject ALL read receipt requests.
That seems to be a more typical setting for most users.

When two users are on the same mail server, it simply depends how the
mail server handles requests. Most (that I've seen) do not
differentiate betwen read/delivery requests from external and
internal users.
