(third-person singular simple present inboxes, present participle inboxing, simple past and past participle inboxed)
An inbox is a repository in an e-mail application that accepts incoming messages. E-mail programs may offer multiple inboxes into which it filters new messages after analyzing their content (see Gmail tabs and Clutter). An "outbox" is where outgoing messages are placed. Inboxes and outboxes function somewhat like folders but are not treated as such in the computer. They are generally consolidated into a database that can only be manipulated from within the mail application. See e-mail.
