Sending Email from web form using php

Question

I wrote a php script to sent email from web form when use clicks a button. The mail is working but it show this warning message in the inbox : "this mail might not have been sent from example@example.com". Here is my php code:

<?php
if(isset($_POST['send'])){

    $to = 'indra.web@satenterprise.com';
    $subject = 'Booking';

    $message = 'Name:' . $_POST['name'] . "\r\n\r\n";
    $message .= 'Email:' . $_POST['email'] . "\r\n\r\n";
    $message .= 'Phone:' . $_POST['message'] . "\r\n\r\n";

    $headers = "From:" .$_POST['email'] . "\r\n\r\n";
    $headers .= 'Content-Type: text/plain; charset=utf-8';

    $email = filter_input(INPUT_POST, 'email', FILTER_VALIDATE_EMAIL);
    if($email){
        $headers .= "\r\nReply-To: $email";
    }

    $success = mail($to, $subject, $message, $headers);

    if(isset($success) && $success){ ?>
         <h4 style="font-family: Arial; color: #777777;">Thank You, your mail has been sent. We will be in touch with you very soon.</h4>
    <?php }else{
        echo "Sorry, there was a problem sending your message";
    }
}
?>

is there any way to do away with this disturbing message? Thank you

$contact_message=$_POST['contact_message'];
$to_email = 'xxx@domain.com'; //you can give email id to whom you need to send
$html = 'your custom body of the mail';
$subject = 'you subject' . $contact_message;
$message = $html;
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From: ABC' . "\r\n"; //DONT GIVE SPACE IN "ABC"  //you can replace your value but no space.. if u give space you can get email in spam only..
$response = mail($to_email,$subject,$message,$headers);
if($response)
