For some reason, I don't think this note is from the real Yahoo!
The Yahoo servers are currently under heavy stress due to unproportional usage of our email services. Thus The Security Yahoo has decided to reduce the number of Yahoo
accounts by a huge margin to regain its potential.
Below the e-mail, I was asked to input the password for the account. Yahoo! always tells me that they would never ask for my password, so ... I didn't give it.
If you, too, have a Yahoo! account -- if only to keep all the spam junk mail out of your work computer -- you may want to be careful.
