goDaddy SMTP-无法从传输连接中读取数据：net_io_connectionclosed

Question

我正在尝试使用 goDaddy smtp 服务器设置邮件功能，Go daddy 支持在这里也不是很有用。

我已经尝试过这些服务器：

relay-hosting.secureserver.net -错误 - 无法连接\

smtpout.secureserver.net -错误 - 无法从传输连接读取数据：net_io_connectionclosed

goDaddy 是这样说的：

这是我的代码 sn-p：

MailMessage mail = new MailMessage("signup@xxx-xxx.com", to);
SmtpClient client = new SmtpClient();
client.Host = "smtpout.asia.secureserver.net";
//Tried "relay-hosting.secureserver.net" -Errors-Unable to connect
//Tried "smtpout.secureserver.net" -Errors-Unable to read data from the transport connection: net_io_connectionclosed
client.Port = 25;
//Tried 80, 3535, 25, 465 (SSL)
client.UseDefaultCredentials = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.EnableSsl = false;
client.ServicePoint.MaxIdleTime = 1;
client.Timeout = 1000;
client.Credentials = new NetworkCredential("signup@xxx-xxx.com", "xxx-xxx");
mail.IsBodyHtml = true;
mail.Subject = "xxx-xxx.com Account Activation";

mail.Body = SomeBigHTMLstring;
client.Send(mail);
mail.Dispose();

这是错误页面

帮帮我。

Answer 1

终于搞定了。有两点需要注意

1. 配置了“中继”的电子邮件只能以这种方式工作，如下图所示。
2. 需要增加超时时间。

client.Timeout = 10000;//was 1000 initialy

Answer 2

问题解决后，您可以使用端口号：3535 和 EnableSSl:false...

MailMessage mail = new MailMessage("signup@xxx-xxx.com", to);
SmtpClient client = new SmtpClient();
client.Host = "smtpout.asia.secureserver.net";

// Tried "relay-hosting.secureserver.net" -Errors-Unable to connect
// Tried "smtpout.secureserver.net" -Errors-Unable to read data from
// the transport connection: net_io_connectionclosed

client.Port = 3535;  //Tried 80, 3535, 25, 465 (SSL)
client.UseDefaultCredentials = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.EnableSsl = false;
client.ServicePoint.MaxIdleTime = 1;
client.Timeout = 1000;
client.Credentials = new NetworkCredential("signup@xxx-xxx.com", "xxx-xxx");
mail.IsBodyHtml = true;
mail.Subject = "xxx-xxx.com Account Activation";
mail.Body = SomeBigHTMLstring;
client.Send(mail);
mail.Dispose();

编码愉快... :-)
