General Information and Terminology
Eudora has both mailboxes and mail folders. Mailboxes are used to store email messages and mail folders are used to store mailboxes. You can put related mailboxes together in the same mail folder to organize them.
For example, say you want to keep each family member's email separate. You could set up two mail folders: Parents and Children. The Parents mail folder could contain a Mom mailbox and a Dad mailbox. The Children mail folder could contain one mailbox for each child. If Mom wants to find her mail, she'd go to the Parents mail folder and open the Mom mailbox within that folder.
