解決什麼問題？

假設現況如下：
個人信箱： summit@gmail.com
群組信箱： program@summit.g0v.tw
而個人信箱是群組信箱的其中一個成員

現在希望用 summit@gmail.com 寄信，
但是當收件者回信的時候，是寄給 program@summit.g0v.tw

設定

  1. 設定新的寄件地址
    參考：Gmail 說明
    或點我進到 Gmail 設定頁面點「新增另一個電子郵件地址」
    1. 修改名稱：g0v Summit 2024
    2. 修改電子郵件地址： summit+g0vsummit2024@gmail.com
      在這邊我們透過 + 與 . 這兩個 Gmail 的魔術符號
      讓 summit@gmail.com 等同於 summit+g0vsummit2024@gmail.com
  2. 取消「視為別名」
    參考：Gmail 說明
  3. 指定不同的回覆至地址為： program@summit.g0v.tw
    參考：Gmail 說明
  4. 按「下一步」
  5. 回 summit@gmail.com 收信
