No

No Single Reply from discountasp.net team member. Is everybody went to the Summer vacation?

 

Free Sandbox features:
Windows Server 2008 R2 Platform
.NET Framework 4.5 beta

50 MB SQL Server 2008 R2 disk space

There is no SMTP service for sandbox program provided by DASP. You can use your own SMTP server.

 

Hi Jayc,

I am using my gmail's smtp server with my username and password, and it requires SSL at client.

Which I think discountasp.net is not providing.

So, I am getting the following expcetion in the code -

System.Net.Mail.SmtpException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at at System.Net.Mail.MailCommand.CheckResponse(SmtpStatusCode statusCode, String response) at System.Net.Mail.MailCommand.Send(SmtpConnection conn, Byte[] command, MailAddress from, Boolean allowUnicode) at System.Net.Mail.SmtpTransport.SendMail(MailAddress sender, MailAddressCollection recipients, String deliveryNotify, Boolean allowUnicode, SmtpFailedRecipientException& exception) at System.Net.Mail.SmtpClient.Send(MailMessage message) at ASP.mailtest_aspx.Page_Load(Object sender, EventArgs e) at System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) at System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

 

It's not that. You don't need SSL as a client. Google wants you to connect to their SMTP over SSL

so what you gotta do, make sure you connect over SSL.

smtp.EnableSsl = true;

 

Hi Jayc,

You have suggested to use port 465, I really doubt that port 465 is blocked at discountasp.net server. Since the code is still throwing an exception.

Operation Timed Out while sending an email

System.Net.Mail.SmtpException: The operation has timed out. at System.Net.Mail.SmtpClient.Send(MailMessage message) at ASP.mailtest_aspx.Page_Load(Object sender, EventArgs e) at System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) at System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Please suggest some alternative to send an email!

But I am still getting operation timeout exception.

Could you please check on the discountasp.net server wether you could able to send an email using any free sandbox account!


Thanks In Advance!

Sandbox server has .NEt framework installed on it. So yes, you can send mail with SMTP from there.

Anyway, I just test this. Its working w/o timeout from Gmail server.

using System.Net.Mail;
using System.Net;


protected void button1_Click(object sender, EventArgs e)
{
MailMessage mail = new MailMessage();


mail.From = new MailAddress ("[email protected]");
mail.To.Add( "[email protected]");


mail.Subject = "Just a test courtesy of DASP";
mail.Body = "Just a test courtesy of DASP";

SmtpClient smtp = new SmtpClient( "smtp.gmail.com");

NetworkCredential Credentials = new NetworkCredential("[email protected]" , "password");
smtp.Credentials = Credentials;

smtp.EnableSsl = true;
smtp.Send(mail);
Response.Write( "message sent!");
}

 

Hi Jayc,

Your code is throwing the following exception. I am sure that sandbox account is configured not to send an email.

<%@ Import Namespace="System.Net.Mail" %>
<%@ Import Namespace="System.Net" %>

<script language="C#" runat="server">
protected void Page_Load(object sender, EventArgs e)
{
MailMessage mail = new MailMessage();
mail.From = new MailAddress("[email protected]");
mail.To.Add("[email protected]");
mail.Subject = "Just a test courtesy of DASP";
mail.Body = "Just a test courtesy of DASP";
SmtpClient smtp = new SmtpClient("smtp.gmail.com");
NetworkCredential Credentials = new NetworkCredential("[email protected]", "xxx");
smtp.Credentials = Credentials;
smtp.EnableSsl = true; smtp.Send(mail);
Response.Write("message sent!");
}
</script>
<html>
<body>
<form runat="server">
<asp:Label id="lblMessage" runat="server"></asp:Label>
</form>
</body>
</html>


The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at.

None of the above code works at all on discountasp.net!

 

Your question has been answered a couple of times. Sorry you can't get it to work, but there's nothing preventing anyone from sending mail from a Labs account.
