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.) > One point of DSN is that the receipt is in machine readable format, > multipart/report, a boiler-plate acknowledgement wouldn't achieve the > same thing. Agreed. -- Bill
