|Stable release||0.9.7.3 / 10 March 2009|
YPOPs! (previously known as YahooPOPs!) is open-source software that provides POP3 and SMTP access to Yahoo! Mail. It is available on the Microsoft Windows, Linux, Solaris and Mac platforms. The project was started by Anuj Seth in 2002 and is now supported by a larger community of developers.
As of 22 August 2011, there do not seem to be any successful current users of ypops because of changes to Yahoo! Mail.
YPOPs! acts as a gateway. It provides a POP3 server interface at one end to communicate with email clients, and an HTTP client (browser) interface at the other which communicates with Yahoo! It does not go against the license agreements of Yahoo! Mail. Email clients that support POP3 and SMTP are supported.
Yahoo! Mail disabled free access to its (US) POP3 service on April 24, 2002 (however paying subscribers to premium Yahoo! Mail services could continue to access POP3).
YPOPs! was inspired by a Perl script called FetchYahoo! written by Ravi Ramkissoon. It has built a large installed base and an active community of people that support users via a discussion forum on its official website.
