How to send two emails in a single contact form using PEAR Mail

Question

I have a contact form and I want to receive message through mail and simultaneously send mail to the client. I have the below code it works some times. That is some times I get the message and client also get the message but sometimes only one email is sent either to client or to me but never both all the time.

I have seen example in the following link https://teamtreehouse.com/community/how-to-send-two-different-email-with-different-bodies-using-phpmailer but it uses PHP Mailer I want the same functionality but by using PEAR Mail.

I have seen other similar question over here PEAR Mail using gmail SMTP won't send 2 emails in sucession but the answer given in that question doesn't solve my problem

Below is the code which works some time.

<?php

require_once('Mail.php');
require_once('Mail/mime.php');

if (isset($_POST['Captcha'])) {
$name = filter_var($_POST['Name'] , FILTER_SANITIZE_STRING);
$email = filter_var($_POST['Email'] , FILTER_SANITIZE_EMAIL);
$phone = filter_var($_POST['Phone'] , FILTER_SANITIZE_STRING);
$budget = filter_var($_POST['Budget'] , FILTER_SANITIZE_STRING);
$timeline = filter_var($_POST['Timeline'] , FILTER_SANITIZE_STRING);
$description = filter_var($_POST['Description'] , FILTER_SANITIZE_STRING);
$spam = filter_var($_POST['usernameoftest'] , FILTER_SANITIZE_STRING); // Bot trap
if($spam) 
    {  // If the hidden field is not empty, it's a bot
                die("No spamming allowed bitch!"); 
    } else {
        $from = "sales@ganeshghate.com";
        $to = "ganeshghate@hotmail.com";
        $subject = "Message from : ".$name;
        $body = "Client's Name : ".$name."\r\n";
        $body .= "Client's Email ID : ".$email."\r\n";

        $body .= "Client's Budget : ".$budget."\r\n";
