I have installed magento 1.7 in wamp->localhost. When i want to send email to the customer from my admin panel "The order email has been sent.", this message appears but the email is not sent to the customer. What should I do? Please help me.
i think you first know if you had your smtp configured ? - Did you configure your smpt on wamp ?

You need some SMTP mail client on your localhost then only you can test the email sending feature from localhost.
