Php Gmail SMTP邮件发送：无错误，邮件未发送

所以本周早些时候，我问如何使用类似于hMailServer的SMTP发送邮件，不知怎的，我开始在本地工作，但它突然需要密码和用户名。 现在我试图通过gmail的smtp服务器发送邮件，但似乎无法正常工作。没有错误消息，邮件未被发送。我能知道我做错了什么吗

代码1-本地主机SMTP工作

代码2-Gmail SMTP不工作

else if ($ways=="netssc"){
$_SESSION['youdont'] = "0";  
$mail->IsSMTP();                         
$mail->Host     = "smtp.gmail.com";            
$mail->SMTPAuth   = true;                
$mail->Port       = 465;                 
$mail->Username   = "pie-company@gmail.com";  
$mail->Password   = "ilovebigpie-chipsdontlie19472013";        
$mail->From     = ("buymy.pie@gmail.com");
$mail->FromName = ("Pie D-licious");
$mail->AddAddress("pielover2013@gmail.com","Valued Customer");
$mail->Subject  = $myusername . "'s Purchases of ". $_SESSION['amount'] ." of XXXX.";
$mail->Body     = $userIName . " owner/user of account " . $myusername ." has purchased " . $_SESSION['amount'] . " (quantity) of  X item(s). Total amount of S$" .  
$_SESSION["payamount"] . ". Payment will be made through NETS/Bank Transfer.";
$mail->WordWrap = 70;

 if(!$mail->Send()) {
  echo 'Message was not sent.';
  echo 'Mailer error: ' . $mail->ErrorInfo;
} else {
  echo 'Message has been sent.';
}

你检查过你的垃圾邮件文件夹了吗。
