I want to send mail from my php site. But i dont have any idea about how to configur it. I am using BigRock Hosting service. And the code below shown is using now as the sendmail.php page to send mail..
$to = $to;
$subject = "My subject here";
$message = "Hello! This is a simple email message.";
$from = "Mymailaddress@example.com";
$headers = "From:" . $from;
echo "Mail Sent.";
