使用mu4e将电子邮件发送到特定地址之前进行确认

Question

我想要一个发送挂钩，要求用户在将电子邮件发送到特定地址（“收件人”或“抄送”或“密件抄送”）之前进行确认。我走了这么远：

(defun confirm-sending-to-certain-addresses ()
  "Double check before sending message to sensitive addresses"
  (or (string-match-p "some@address.com" (message-field-value "To"))
      (yes-or-no-p "Really send to a sensitive address ? ")
      (keyboard-quit))))

(add-hook 'message-send-hook #'confirm-sending-to-certain-addresses)

这不起作用。我怀疑message-field-value在该contaxt中不起作用。

任何提示表示赞赏！
