i 正在建立一个电子邮件客户,从服务器机组而不是员工和管理当局协调会发送电子邮件地址,我写道:
SmtpClient server = new SmtpClient();
server.Host= "50.23.128.66";
server.Port = 25;
server.Send("[email protected]", "[email protected]", "hi", "hope it works");
但是,如果发生错误,即:
Unhandled Exception: System.Net.Mail.SmtpException: Service not available, closing transmission channel. The server response was: Cannot connect to SMTP server 50.23.128.66 (50.23.128.66:25), connect error 10061
i 实际上认为港口是错误的。 ∗∗∗ 采用“视窗服务器”的方式
我认为,“连接错误10061”与定位台平台上的电离层=ESCONNREFUSED相同,这意味着连接不会成功,可能是因为东道方试图连接25号港口的任何服务器。
根据这项员工和管理当局协调计划服务器测试。 服务器不能在25港口接收连接:
由于目标机器积极拒绝该目标机50.23.128.66:25
It s possible the server uses some form of encryption, and you will have to connect on one of the "secure" SMTP ports.
你们是否相信它是一个员工和管理当局协调会的服务器,而不是一个技转方案服务器或类似的服务器?
