YahooPOPs! is an open-source initiative to provide free POP3 access to your Yahoo! Mail account.
This application emulates a POP3 server and enables popular email clients like Outlook, Netscape, Eudora, Mozilla, Calypso, etc., to download email from Yahoo! accounts.
This application acts like a gateway. It provides a POP3 server interface at one end to talk to email clients and an HTTP client (browser) interface at the other which allows it to talk to Yahoo!
YahooPOPs! is also available for UNIX @ the authors site
