如何使用带有localhost SMTP的PHPMailer将邮件发送到gmail？

I try to send email using PHPMailer, here my code:

require '/PHPMailer-master/PHPMailerAutoload.php';
$mailltoadm = new PHPMailer;
$mailltoadm->isSMTP();     
$mailltoadm->Host = 'localhost';  
$mailltoadm->SMTPAuth = true;     
$mailltoadm->Username = 'admin@queenshifa.com';  
$mailltoadm->Password = 'mypasswordhere';  
$mailltoadm->SMTPSecure = 'tls'; 
$mailltoadm->From = $emaillogin; 
$mailltoadm->FromName = $userloginname; 
$mailltoadm->addAddress($mastermaill, $name_store);
$mailltoadm->addAddress($mastermaill);  
$mailltoadm->addReplyTo($emaillogin, $userloginname);
$mailltoadm->WordWrap = 50;
$mailltoadm->isHTML(true);  
$mailltoadm->Subject = 'New Order '. $name_store;
$mailltoadm->Body    = $finishorder; 
$mailltoadm->AltBody = convert_html_to_text($finishorder);
if(!$mailltoadm->send()) 
{
   echo 'Mailer to admin Error: ' . $mailltoadm->ErrorInfo;
} 
else 
{
   echo 'Message to admin has been sent';
}

Why email send to @yahoo.com success, but not send to @gmail.com ?
can any one help me please.

If you can really receive emails on @yahoo and don't have them @gmail it simple means that Google blocks your emails. You should definitely check your spam folder on Gmail because your emails probably are there.
