mail.php脚本不适用于订阅和联系页面[重复]

My web developer made this script to send notifications to people subscribing to my mailing list and the people who contact me, through the form on my website The problem is, the recipients are not able to receive the emails, and I am not able to receive the notification on my mail id about a new subscriber or a contact

Sender id - notifications@llaveshagarwal.com

Moreover, the same script works on his server (which we used for testing) but doesn't work on my server

Is there a problem with my SMTP server settings ? Also, I am using Google Apps for Gmail Here is his script

What should I do ?

<?php
if($_POST['type'] == "subscribe") {

/*$to = "notifications@llaveshagarwal.com";
    $subject = "New Email Subscriber";
    $txt = "Name: ".$_POST['name']."
From: ".$_POST['from'];
    $headers = "From: ".$_POST['from'];

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

    $to = $_POST['from'];
    $subject = "Thank you for subscribing with us.";
    $txt = "Hey ".$_POST['name']." ,

    $db= mysql_select_db('llavesha_contact_system', $link);

    $insert='insert into subscribe (name,email) values ("'.$_POST["name"].'","'.$_POST["from"].'")';
    if(mysql_query($insert)) {
