Hi,
someone on IRC asked about how to make a function that delays sending of
email, so as to have a chance to edit/cancel within 2 minutes or so. I
came up with
(defun message-wait-send-and-exit (&optional arg)
"Bury the buffer and wait a bit, then send message like
`message-send-and-exit'."
(interactive "P")
(let ((timeout "2 minutes")
(buf (current-buffer)))
(message "Sending %s in %s" buf timeout)
(bury-buffer)
(run-at-time timeout
nil
(lambda (arg buf)
(when (buffer-live-p buf)
(with-current-buffer buf
(let ((inhibit-quit nil)) ; avoid hang if e.g. server is slow/down
; though this makes C-g dangerous
(message-send-and-exit arg)))))
arg
buf)))
but I know it's fraught with problems (missing headers cause
interactive questions to pop up out of nowhere, a C-g at the wrong
moment will cancel sending).
Has anyone attempted something like this before? I guess to avoid the
problem of interactive questions you'd have to write your own version of
`message-send' and do the `run-at-time' there. Perhaps `with-timeout'
could be used along with inhibit-quit to avoid stray C-g's while still
not hanging on server trouble? (Or is this a much bigger project than
that?)

When I want delayed sending of an email/article, instead of using C-c
C-c to send it, I go C-c C-j (which is bound to gnus-delay-article).
Then I am prompted about how long to delay it, or when to send it. After
answering that, the email shows up in nndraft:delayed until the set
time, when it is sent.
In my .gnus I have these things to make it work:
; Activate delayed messages:
(gnus-delay-initialize)
; Show X-Now-Playing and X-Gnus-Delayed header:
(setq gnus-visible-headers (concat gnus-visible-headers "\\|^X-Now-Playing:\\|X-Gnus-Delayed:"))
; Remove date, so delayed messages (C-c C-j) don't get a date until
; sent <mailman.1180.1266014215.14305.info-gnus-english@gnu.org>:
(setq message-draft-headers '(References From))
Only the first one is essential, I think. Oh, and the documentation of
gnus-delay-article says that delayed messages are sent after new news is
fetched, which means that these lines in my .gnus:
; Demon to fetch email every 5 minutes when Emacs has been idle for 5 minutes:
(gnus-demon-add-handler 'gnus-demon-scan-news 5 5)
(gnus-demon-init)
probably are essential as well. (And sending is potentially ~5 minutes
off.)
Maybe you can build upon gnus-delay-article if you want a fixed delay?
Best regards,
Adam

See (info "(gnus)Delayed Articles")
Bye, Reiner.

I should have offered a link to the manual as well, it has more detail:

Thanks, Adam and Reiner, I should've guessed it was solved already :)
I prefer a shorter demon timeout for this purpose, but I don't need the
full news scan, so I used
(gnus-demon-add-handler 'gnus-delay-send-queue 1 nil) ; call every other minute regardless of idleness
(gnus-demon-init)
And for the actual sending, in case anyone's interested:
(defvar message-delayed-send-default-minutes 2
"Default delay in minutes before delayed-sending with `message-delayed-send-and-exit'")
(defun message-delayed-send-and-exit ()
"Use `gnus-delay-article' to send after
`message-delayed-send-default-minutes' minutes."
(interactive)
(message "Sending in %s minutes" message-delayed-send-default-minutes)
(gnus-delay-article (format "%sm" message-delayed-send-default-minutes)))
(define-key message-mode-map (kbd "C-c C-c") 'message-delayed-send-and-exit)
And in case I exit gnus before it's sent, I added:
(defun gnus-delay-send-queue-hurry ()
"As `gnus-delay-send-queue, but also send anything that is to
be sent within `message-delayed-send-default-minutes minutes."
(interactive)
(save-excursion
(let* ((group (format "nndraft:%s" gnus-delay-group))
(message-send-hook (copy-sequence message-send-hook))
articles
article deadline)
(when (gnus-group-entry group)
(gnus-activate-group group)
(add-hook 'message-send-hook
(lambda () (message-remove-header gnus-delay-header)))
(setq articles (nndraft-articles))
(while (setq article (pop articles))
(gnus-request-head article group)
(set-buffer nntp-server-buffer)
(goto-char (point-min))
(if (re-search-forward
(concat "^" (regexp-quote gnus-delay-header) ":\\s-+")
nil t)
(progn
(setq deadline (nnheader-header-value))
(setq deadline (apply 'encode-time
(parse-time-string deadline)))
;; The difference:
(setq deadline (time-subtract
deadline
(seconds-to-time
(* 60 message-delayed-send-default-minutes))))
(setq deadline (time-since deadline))
(when (and (>= (nth 0 deadline) 0)
(>= (nth 1 deadline) 0))
(message "Sending delayed article %d" article)
(gnus-draft-send article group)
(message "Sending delayed article %d...done" article)))
(message "Delay header missing for article %d" article)))))))
(add-hook 'gnus-exit-gnus-hook 'gnus-delay-send-queue-hurry)
(I guess another possibility would be to first go through nndraft and
alter the header, then call `gnus-delay-send-queue', but most of that
function consists of finding delayed articles anyway …)

Ah, cool, I will steal that - thanks for sharing (this and the rest)!
