------解决方案--------------------
我前段时间用java写了一个收发邮件的小程序，如果需要的话，给个邮箱我发给你。
------解决方案--------------------
SMTP host
你邮箱定义的smtp有问题 不如用网上的 比如qq sina什么的
报错显示无法连接 超时

------解决方案--------------------
192.168.2.211:25？这是哪儿的地址端口，看着就像个内网地址，你确定你能访问吗？telnet一下，ping一下。排除地址无法连接的错误
------解决方案--------------------
25端口是非SSL端口，994是SSL端口
------解决方案--------------------
192.168.2.211是内网的邮件服务器？
可能连接有问题
------解决方案--------------------
