Please explain how the current delivered-to draft does not satisfy these uses
with a single field.
If an MUA wants to learn the envelope recipient address to which the
message was sent (by the immediate upstream MUA or relay) then Delivered-To
is not the right header for that. That's why Exim has Envelope-To, while
Postfix has "X-Original-To:", both of which are intended for consumption by
tools like fetchmail.
So you are saying that it is not possible for one Delivered-To to show
the actual address it has been delivered to, followed by another
Delivered-To that shows a local transformation to an internal delivery
string?
Or are you saying that Delivered-To has nothing to do with delivery?
The draft as written does not preclude the present use of Delivered-To, but
its "Experimental" status still makes no sense to me,
1. That's irrelevant to the current issue.
2. It's been explained. Please refer to my earlier note that provides
quite a bit of detail for that explanation.
