Is it possible to send a mail in PHP without any external packages or tools? If so, is there

any requirement to configure the php.ini file?

Its as follows:

$to = $row->EMail_ID;

        $subject = "Reset your password";

        $body = "Hi ".$row->Username.", \n\t\t\tA request to reset your  password was received from you. \n\n\n";

        $headers = "From: [email protected]\r\n"."X-Mailer: php/";

        mail($to, $subject, $body, $headers); 

The error i get:

Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25,

verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in F:\wamp\www\pwd.php on line 20
