You bet. But you need Mail Plus to do it.

Email forwarding sends your email to another address that you provide. Instead of your mail going into your Yahoo! Inbox, it's forwarded to the other account's inbox so you can check it there. While forwarding is "on," you won't get any mail in your Yahoo! account.

Back up your entire email account or mass-download messages to your local computer with Mail Plus message archiving. It's convenient. And it's secure.
