【问题描述】:
我是新的 ASP.Net,正在尝试解决邮件问题。我的网站托管在 Godaddy 服务器上,并在 ASP.Net 中开发。尝试使用以下脚本发送邮件,但抛出错误为 “发送邮件失败”
MailMessage mail = new MailMessage("firstmail@mail.com", "sfirstmail@mail.com");
SmtpClient client = new SmtpClient();
client.Host = "myhosting.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 = 10000;
client.Credentials = new NetworkCredential("myloginid@mail.com", "mypassword");
mail.IsBodyHtml = true;
mail.Subject = "New Job";
mail.IsBodyHtml = true;
try
{
client.Send(mail);
mail.Dispose();
Response.Redirect("thankyou.html");
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
当 Print 异常在 ex 中得到以下内容:
System.Net.Mail.SmtpException:发送邮件失败。 ---> System.IO.IOException:无法从传输中读取数据 连接:net_io_connectionclosed。在 System.Net.Mail.SmtpReplyReaderFactory.ProcessRead(字节 [] 缓冲区, Int32 偏移,Int32 读取,布尔读取线)在 System.Net.Mail.SmtpReplyReaderFactory.ReadLines(SmtpReplyReader 调用者,布尔 oneLine)在 System.Net.Mail.SmtpReplyReaderFactory.ReadLine(SmtpReplyReader 调用者)在 System.Net.Mail.CheckCommand.Send(SmtpConnection conn, 字符串和响应)在 System.Net.Mail.MailCommand.Send(SmtpConnection conn, Byte[] 命令, MailAddress from, Boolean allowUnicode) at System.Net.Mail.SmtpTransport.SendMail(邮件地址发件人, MailAddressCollection 收件人,字符串 deliveryNotify,布尔值 allowUnicode、SmtpFailedRecipientException& 异常)在 System.Net.Mail.SmtpClient.Send(MailMessage message) --- 内部结束 异常堆栈跟踪 --- 在 System.Net.Mail.SmtpClient.Send(MailMessage 消息)在 _Default.SendEmail(Object sender, EventArgs e)

-
查看异常消息,似乎端口、EnableSsl 或主机 smtp 服务器的设置不正确。请联系您的提供商以获取正确的设置。
