I accidentally sent a post three times to gnu.emacs.help - sorry
about that, but perhaps it wasn't so grave a mistake because some
lists/groups and/or clients (?) discard duplicate messages as
flood/spam protection - anyway, I tried
gnus-summary-cancel-article
but it said
Couldn't send message via news: 441 Invalid Control Message
My question - is this anything that works anymore or is it a
wasted effort, perhaps especially for the list/group hybrids?

,----[ (info "(gnus)Canceling and Superseding") ]
| Have you ever written something, and then decided that you really,
| really, really wish you hadn’t posted that?
|
| Well, you can’t cancel mail, but you can cancel posts.
|
| Find the article you wish to cancel (you can only cancel your own
| articles, so don’t try any funny stuff). Then press ‘C’ or ‘S c’
| (‘gnus-summary-cancel-article’). Your article will be canceled—machines
| all over the world will be deleting your article. This command uses the
| process/prefix convention (*note Process/Prefix::).
|
| Be aware, however, that not all sites honor cancels, so your article
| may live on here and there, while most sites will delete the article in
| question.
`----
So probably your news server doesn't honor cancels. I remember that
some time ago, I did cancel an article of mine at our local news server,
so it should work in certain cases.
Bye,
Tassilo

My news server rejects Gnus's cancel messages unless I change the
control message's "Subject" field from "cmsg cancel" to "cancel". I do
this change automatically with message-cancel-hook (see below). Years
ago I browsed news server's control message group and learnt how to make
cancel messages work.
(add-hook 'message-cancel-hook 'tl-message-cancel-hook)
(defun tl-message-cancel-hook ()
(save-excursion
(save-restriction
(save-match-data
(message-narrow-to-head)
(let ((case-fold-search nil))
(when (re-search-forward "^Subject: \\(cmsg \\)cancel" nil t)
(delete-region (match-beginning 1) (match-end 1))))))))

Yeah - at least, I didn't get any error message, so I guess it
worked! Wow!

I've now changes message.el to use "cancel" instead of "cmsg cancel".
