php imap接收qq邮件的问题

Question

写一个接收邮件的代码，提示无法连接，qq邮箱已开启imap，下面贴上代码，麻烦各位帮忙看看？

$host = '{imap.qq.com:993/imap/ssl}INBOX';
$user = '*****';
$pass = '*****';
$inbox = imap_open($host, $user, $pass)or die("can't connect: " . imap_last_error());   
$mailboxes = imap_list($inbox, $host, '*');
$mailboxes = str_replace($host, '', $mailboxes);
print_r($mailboxes);

贴上错误代码：从腾讯邮箱看到地址是imap.qq.com 提示报错。。

是不是没有用授权码登陆？
