Question

我正在使用VPN，但我不认为这是问题所在。我将防火墙设置为允许传出连接，而我的McAfee则忽略了Eclipse和Java。

我知道这看起来像重复的。我保证不是。我已经尝试了过去三天在Stack Overflow上发现的所有内容，但这仍然给了我

是否有明显的事情我做错了？我已经至少完成了该课程的5次完整改版，并欢迎提出建议。预先谢谢你。

其他人都知道，问题出在网络防火墙/安全性上。显然，即使我将网络管理员级别的访问权限绑定到我的Active Directory帐户上（通过VPN访问），通过VPN连接显然也没有给Java程序足够的特权来运行电子邮件程序。我能够在具有营业场所的物理位置并且与网络进行有线连接的服务器上对此进行测试。
