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))))))))
