解决方案

检查您的主机地址是否正确。我认为代码中缺少SMTP客户端的端口。检查你的Smtp客户端是否需要安全连接（SSL）。问题可能是因为上述三个中的一个。

解决方案

Check whether your host address is correct or not.  I think  Port for your SMTP Client is missing in the code. Also do check whether your Smtp Client require Secure Connection (SSL) or not. The problem could be because one of above three.
