I have received the following mail in my yahoo mail account. Just observe the mail and you will find -
1. It was addressed to Recipients (Not my name)
2. It is asking for my User Name and Password and email address.
3. It does not say either yahoo mail or gmail or any other mail.
These should be enough to indicate that it is a fake mail asking for our details and the purpose is to hack our account.
So be careful if you receive such mails. Please do not respond. Just delete such mails without even opening it
Thanks and Regards
