このアドオンについて
This add-on adds a button to the message window which allows the recipient to reject messages with deficiencies like missing or wrong subjects or meaningless message bodies. The user is then prompted for the rejection reasons and a reply mail is prepared "ready to send". Use this to enforce proper mail ettiquette, annoy all your colleagues and friends and eventually get beaten up in a dark alley.
