Yahoo! Mail API announced
Yahoo! announced a new API that allows for developers to access a Yahoo! user's mail preferences, messages, and folders. This allows for the ability to search messages, and get mail from POP accounts. The new SOAP API was officially pre-released at the Yahoo! Hack Day conference on the September 29th. Documentation for the new API can be found on the Yahoo! Mail developer list when you sign up for that group. Sounds promising for outside developers that want a crack at building something useful for Yahoo! mail users, not to mention all of the Web 2.0 integration that could pop up.
