DSN here corresponds to http://www.dsn.org/ , correct?

I agree that an action-required prompt is very obtrusive.

A button would correspond to the value 1 below when emacs is running
with a viable mouse.  A more primitive form of 1 would be provided
for classical interactive terminals.

I intended to suggest a user-configurable variable such as this:

(defvar gnus-return-receipt-request-handling 0
"*Handling for DSN-related return-receipt requests in incoming items.
Meaning:  0 = Ignore all return-receipt requests.
          1 = Provide a styled display of the phrase
              \"Return Receipt Requested\"
              just after the displayed message headers and offer
              the function gnus-send-return-receipt in a non-obtrusive
              way.
          2 = Honor all return receipt requests.)

Agreed.
