How do I report someone who is disguising as a yahoo admin to confirm my acct?

I am getting a few emails from admin@yahoo.com, register@yahoo.com and mail@yahoo.com indicating that my password has been updated when I have not changed it. Additionally, I have received emails in the Subject line: "Detected Online User Violation", "Your account is Suspended for Security Reasons" and "Warning message: Your services near to be closed". Who can I report these to?|||Forward them to "abuse@yahoo.com" and delete them as spam. Also, never reply to the link in an email that requests passwords or to verify account information. Access the website directly to be sure that you are interacting with the real deal instead of a phishing expedition.
