Mail and Newsgroups automatically looks for new messages when it starts, then every ten minutes or so while it is running. To check for new mail at any time, click on the Get Msg button on the toolbar, or choose Get New Messages from the File menu.

Netscape delivers all new mail to the Inbox. Any messages you haven’t deleted or filed will also be in the Inbox.  Messages which have not been read are in bold.
 

Click on the Inbox icon to view its contents. Messages in the folder will be listed in the right hand panel. You can change the order in which messages are listed with the Sort command in the View menu, or by Clicking on the column headers (Subject, Sender, etc).
