When you login to SquirrelMail, the contents of your Inbox will be displayed and new mail will be listed at the top of the message list. However, you may wish to access mail you have received previously. Not all of your messages are listed on one page as this would make it hard to see and scroll through. You can use the navigation links to move through your mailboxes. These will be displayed at the top of your mailbox:
You will see links to navigate to the next page as well as numbers representing the subsequent pages you can access. You can click on Show All to display all your messages on one page.
