Php 在Opencart中注册时发生fsockopen（）错误

首先，邮件通知在OpenCart 2.0.2.0中不起作用。我尝试使用gmail smtp并尝试登录注册，这是错误消息。我得到：

警告：fsockopen（）[function.fsockopen]：php_network_getaddress:getaddrinfo失败：第168行/home/spicycom/public_html/system/library/mail.php中的名称或服务未知警告：fsockopen（）[function.fsockopen]：无法连接到：465（php_network_getaddrinfo:getaddrinfo失败：名称或服务未知）第168行的/home/spicycom/public\u html/system/library/mail.php中注意：错误：php\u network\u getaddresses:getaddrinfo失败：第171行的/home/spicycom/public\u html/system/library/mail.php中的名称或服务未知（0）

请告诉我如何解决这个问题

这是snipet的邮政编码

请提供一些代码片段！我现在就这么做了。谢谢
