用email发送邮件问题， 求大神帮忙

123tsg

Email类配置163邮箱发送成功
Email类配置QQ邮箱发送邮件失败，不知道是什么问题（qq邮箱的smtp已设置）
smtp.exmail.qq.com 和 smtp.qq.com都失败
    private $config = array(
        'protocol' => 'smtp',
        'smtp_port' => 25,
        'smtp_timeout' => 5,
        'wordwrap' => true,
        'wrapchars' => 20,
        'mailtype' => 'html',
        'charset' => 'utf-8',
        'validate' => true,
        'newline ' => '\r\n',
        'crlf' => '\r\n'
    );
