Question

我是新的ASP.Net并尝试修复邮件问题。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);

    }

当打印异常时，在ex：

中得到以下内容

System.Net.Mail.SmtpException：发送邮件失败。 ---＆GT; System.IO.IOException：无法从传输中读取数据连接：net_io_connectionclosed。在 System.Net.Mail.SmtpReplyReaderFactory.ProcessRead（Byte []缓冲区， Int32 offset，Int32 read，Boolean readLine）at System.Net.Mail.SmtpReplyReaderFactory.ReadLines（SmtpReplyReader caller，Boolean oneLine）at System.Net.Mail.SmtpReplyReaderFactory.ReadLine（SmtpReplyReader 调用者）在System.Net.Mail.CheckCommand.Send（SmtpConnection conn，字符串和放大器; System.Net.Mail.MailCommand.Send（SmtpConnection。） conn，Byte []命令，MailAddress from，Boolean allowUnicode）at System.Net.Mail.SmtpTransport.SendMail（MailAddress sender， MailAddressCollection收件人，String deliveryNotify，布尔值 allowUnicode，SmtpFailedRecipientException＆amp;例外） System.Net.Mail.SmtpClient.Send（MailMessage消息）---内部结束异常堆栈跟踪--- at System.Net.Mail.SmtpClient.Send（MailMessage消息）at _Default.SendEmail（Object sender，EventArgs e）

如果您想使用端口465等，则应设置client.EnableSsl = true

此配置适用于我：

    MailMessage message = new MailMessage
    {
      IsBodyHtml = true,
      Body = "text",
      Subject = "subject",
      To = { "firstmail@mail.com", "sfirstmail@mail.com" }
   };

   message.From = new MailAddress("sender@email.com");

   SmtpClient client = new SmtpClient("myhosting.secureserver.net", 465)
   {
      Credentials = new NetworkCredential("myloginid@mail.com", "mypassword"),
      EnableSsl = true
   };

   client.Send();

电子邮件无法在ASP.net
