==== 邮件搭好后可以在foxmail配置成功，不过smtp端口要设为587,可以实现邮件的发送，但是当我在项目中使用改服务器时出错。
项目中的邮件服务器配置代码（CI框架）：
$config['protocol'] = 'smtp';
$config['smtp_host'] = "mail.moceancloud.com";
$config['smtp_port'] = 587;
$config['smtp_user'] = "zhaowei";
$config['smtp_pass'] = "";
$config['wordwrap'] = TRUE;
$config['mailtype'] = "html";
提示错误信息：
