I'm Using Cpanel to host my web site. Is there any special configurations to do this? I'm new to php. Please help me.

Answer 1

mail function doesn't provide authentication functionality. Your have to use Mail class from Mail Pear package. See here for an example:
example

Answer 2

I am assuming you are on shared hosting based on the fact that you are using Cpanel, some shared hosting solutions don't play nicely with php's mail() function, I have found that using phpmailer https://github.com/PHPMailer/PHPMailer works better and provides more functionality
to use phpmailer :
download from the link, place the files in your a folder accessible to your web application.
code :
$email_from = $_POST['email'];
$email_from = "from#gmail.com"; // this overwrites the $_POST['email'] value, check this
$email_from_name = "Nishanthi";
$gmailUsername = "from#gmail.com";
$gmailPassword = "mysecretpassword";
$mail_to_send_to = "to#gmail.com";
$your_feedbackmail = "from#gmail.com";
$emailSubject = "Place Subject Here";
$emailContent = "This message can contain <b>HTML</b>";
require '[path_to_your_phpmailer_files]/PHPMailerAutoload.php';
$mail = new PHPMailer;
//$mail->SMTPDebug = 3; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
// 0 = off (for production use)
// 1 = client messages
// 2 = client and server messages
$mail->SMTPDebug = 2; //Enable SMTP debugging
$mail->Debugoutput = 'html'; //Ask for HTML-friendly debug output
$mail->Host = 'smtp.gmail.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = $gmailUsername; // SMTP username
$mail->Password = $gmailPassword; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587; // TCP port to connect to
$mail->setFrom($email_from, $email_from_name);
$mail->addAddress($mail_to_send_to);
$mail->addReplyTo($your_feedbackmail);
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = $emailSubject;
$mail->Body = $emailContent;
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message was sent, you can send another one';
}
?>
