Disposition-Notification-To acks

[jidanni]

Gentlemen, the Taiwan Power Company has turned off my e-bill account
because gnus doesn't acknowledge the Disposition-Notification-To
headers they send.

They could have gone further and canceled my electricity -- meaning no
more messages from me for you to read. Then where would you all be?
Running around like chickens with your heads cut off, I'm sure.

For now I will do
;;Be sure we are very aware of Disposition-Notification requests
;;though we can only respond manually at present.
(add-hook
 'gnus-startup-hook
 '(lambda ()
    (require 'gnus-art)
    (setq gnus-visible-headers
	  (concat "^Disposition-Notification-To:\\|"
		  gnus-visible-headers))
    (setq gnus-header-face-alist
	  (cons '("Disposition-Notification-To:"
		  gnus-summary-cancelled ;vivid
		  gnus-summary-cancelled)
		gnus-header-face-alist))))

Sure, there is message-insert-disposition-notification-to to insert
them, but no facility to respond to them.

Or a variable that one could set to ask "This message asks for
Disposition Notification, shall we? [yn?]". (('always,'ask,'never,
'warn-only)on sender regexp alist).

Is it gnus' job to respond to them? I believe that it is the
responsibility of the MTA making the local delivery (ie the one from
which gnus fetches mail) to respond to Disposition-Notification-To
headers.

Nope, it's a MUA thing.  Quote from RFC3798:

<quote>
2.1.  The Disposition-Notification-To Header

   A request for the receiving user agent to issue message disposition
   notifications is made by placing a Disposition-Notification-To header
   into the message.
</quote>

However, the bug in this case is cleary on the Taiwan Power Company
side, since the quoted section continues

<quote>
   The presence of a Disposition-Notification-To header in a message is
   merely a request for an MDN.  The recipients' user agents are always
   free to silently ignore such a request.
</quote>

So Gnus is behaving correct by default.

If someone would like to implement it properly (conforming to RFC
3798), fine.

Bye, Reiner.

That's a joke, right?

Do other MUAs actually respond automatically to that header?  I hope not
many, as it would only encourage idiots to start relying on it.

Outlook does it if some option is set (I don't know the default
value).  Thunderbird also has an option for it, or was it for
"Return-Receipt-To"?

It's also nice for spammers to verify the address. ;-)

For this message that you are reading, I have used
message-insert-disposition-notification-to (C-c M-n) and also added a
Key: header, as Taipower does.

Assuming those headers make it to this list, perhaps a user of some
more advanced MUA could allow it to act on this message so I can see
if the result matches http://www.faqs.org/rfcs/rfc3798.html and base
any future handcrafted acknowledgements to Taipower on it.
