Here is my code:

<?php
$name = $_REQUEST['name'] ;
$mobile = $_REQUEST['mobile'] ;
$email = $_REQUEST['email'] ;
$message = $_REQUEST['message'] ;

require 'phpmailer/PHPMailerAutoload.php';

$mail = new PHPMailer;
$mail->SMTPDebug = 2;                               // Enable verbose debug output
$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com';                 // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = 'milindbhuvad1988@gmail.com';                 // SMTP username
$mail->Password = '********';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587;                                    // TCP port to connect to
$mail->setFrom('milindbhuvad1988@gmail.com', '');
$mail->addAddress('milindbhuvad1988@gmail.com', '');     // Add a recipient
$mail->addAddress('milindbhuvad1988@gmail.com');               // Name is optional
$mail->addReplyTo('info@example.com', 'Information');
$mail->addCC('cc@example.com');
$mail->addBCC('bcc@example.com');
$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
$mail->isHTML(true);                                  // Set email format to HTML

$mail->Subject = 'You have received feedback from your website!';
$mail->Body    = "
<strong>Name:</strong> $name <hr>
<strong>Name:</strong> $mobile <hr>
<strong>Email:</strong> $email <hr>
<strong>Message:</strong> $message <hr>";

$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) {    
echo 'Message could not be sent.';    
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {   
?>
<script type="text/javascript">         
alert('Thanks Your Feedback');          
window.location.href='index.html';  
</script>';
<?php
}
?>

Answer 1

Remove $mail->addAttachment('/var/tmp/file.tar.gz'); $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); or link to an actual attachment you want to send. Also updating the certificates in the php.ini worked for me.
