This mailbox category displays all the mail you have received but not filed.  It includes both unread mail and mail you have read.  These show with different icons. 

The "open eye" icon means that the email is Unread (or unseen) and the "question mark folder" icon means that you have viewed it, but it is not yet Filed.  After you have viewed any unread mail, the icon will change from the "open eye" to the "question mark folder." Ezian regards when you highlight an email heading to display it in the window below and then move the cursor to highlight another as having read that email.

As you read your mail, it is a good idea to File it using the File Button in the middle of the Mailbox screen, which will place that piece immediately into mailboxes which you designate by a choosing or creating one or more keywords.  If you choose not to file your mail, it will be moved automatically after reading it into the Unfiled Mail category where you can read it again and file it whenever you wish.
