Using an anonymous proxy server allows you to access websites, including Yahoo! Mail using the anonymous server. This means that the proxy server will hide your IP address from the website you want to access. Therefore, accessing Yahoo! Mail through an anonymous proxy server allows you to use the Web-based e-mail service anonymously. You can use free and paid anonymous proxy services to access your Yahoo! Mail account.

Double-click the anonymous proxy service icon on your computer to open the application.
Select a server. Some anonymous proxy services allow you to select your server location from a list of several available servers.
Click the "Connect" button to connect to the anonymous proxy server.
Double-click a Web browser on your computer.
Enter "yahoo.com" in the search bar.
Click the "Mail" link on the left side of the Yahoo! home page.
