There's a third folder on most email programs called an " outbox."

大多数件程序中还有一个叫“发件箱” 的第三个文件夹。

An " outbox" contains the messages that you are ready to send, but haven't actually sent yet.

“发件箱” 包你发送但实际还未发出的消息。

So your outbox contains messages ready to send; your sent mail folder contains messages you've already sent in the past.

所以你的发件箱包发送的消息；你的已发送件夹包你过去已经发送的消息。
