YPOPs! (formerly YahooPops!) allows you to collect your Yahoo webmail from within your POP email client such as Outlook, Outlook Express, Thunderbird, Eudora, Pegasus and many, many more.
Even though Yahoo! Mail has disabled free access to its POP3 service since 24th April, 2002 this application emulates a POP3 server and enables you to download email from your Yahoo! account (without going against the license agreements of Yahoo! Mail).

For more information visit the site (be sure to check out the FAQs), and here you can download it too.
