LNMP1.7 fsockopen(): failed to create an SSL handle

lyjs

我用的lnmp1.7搭建的Linux centos7 lamp 环境  php 是5.3版本我用CI框架的发送邮件功能一直提示出错，我排查原因最终确认是  fsockopen() 函数执行不成功导致的。
然后我把函数单独拿出来测试：

error_reporting(-1);
ini_set('display_errors', 1);
$fp = fsockopen("ssl://smtp.163.com", 465, $errno, $errstr, 30);
var_dump($fp);


果然提示我有问题：fsockopen(): failed to create an SSL handle；   fsockopen(): Failed to enable crypto；

然后我先打印了phpinfo  发现openssl 已经安装了，使用php -m 命令查看也有openssl扩展

有人说是证书问题  ，我下载了证书配置后重启apache 也不起作用，请教下这究竟是哪里的问题呢，我现在已经没有任何头绪了，请帮忙看一下 谢谢了

你服务器是哪家？有些商家会屏蔽邮件相关的端口
