大多数电子邮件程序有第三件夹， 称为“发件” 。

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

“发件” 包含您准备发送但尚未实际发送的消息。

And when I was done, I would put them in the " outbox" (outbox) – all one word.

当我完成后，我会把它们放在“发件” （outbox）——一词。

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

所以您的发件包含准备发送的消息；您的已发送邮件件夹包含您过去已经发送过的邮件。

Get desk organizers — cups for pens, bins that rest inside drawers to sort small things like paperclips, and an inbox and outbox for mail.

准备办公桌收纳用品——笔筒、可放在抽屉里分类小物件（如回形针）的盒子，以及收发信件的收件和发件。

So, we have an " inbox, " and an " outbox." Well, one of the things you can send via email – that is, through email, is " attachments." An " attachment" (attachment) is another file.

所以，我们有一“收件” 和一“发件” 。嗯，您可以通过电子邮件发送的东西之一 - 即通过电子邮件， “附件” 。 “附件” （附件）另一件。
