In the function that I add to `message-send-hook' I do the following:
(message-goto-body)
;; If already set, don't override.
(if (not (looking-at (regexp-quote "<#secure ")))
;; If we can encrypt, do so, else just sign.
(if (and encrypt (dme:message-determine-encryption))
(insert "<#secure method=pgpmime mode=signencrypt>\n")
(insert "<#secure method=pgpmime mode=sign>\n"))))
Where `dme:message-determine-encryption' is:
(defun dme:message-determine-encryption ()
"Return `t' if we have gpg public keys for all recipients of
this message."
(require 'pgg)
(if (not (message-news-p)) ; No encryption for news.
(catch :exit
(mapc
(lambda (addr)
(if (not (pgg-lookup-key (downcase (mail-strip-quoted-names addr))))
(throw :exit nil)))
(message-tokenize-header (concat
(message-fetch-field "to")
","
(message-fetch-field "cc"))))
t)
nil))
(I'd probably re-write that to use a cl loop now - it's very old.)
