Hi Shankar,
Wildhoney is correct; you'll need to identify an SMTP server within the php.ini file, because Windows does not come with a built-in mail server. However, to minimize the hassle I suggest using the PEAR Mail package (http://pear.php.net/package/Mail) as it allows you to pass along other authentication information which is often required by mail servers to prevent spamming. For instance you could easily use the Mail package to authenticate to Gmail and send email through your Gmail account.

Hope this helps,
Jason
