It has been reported, and verified, that multiple web-mail service providers have been compromised and tens of thousands of usernames and passwords have been leaked. Services compromised included Yahoo! Mail, Gmail, Hotmail (to included MSN Mail and Live.com mail), AOL Mail, and others. It is highly recommended that anybody actively using one of these services change their passwords IMMEDIATELY. Let me know in the comments if you have any questions.
