hi all,
I've been sending email using a console app, and all of a sudden it stopped
working. The EXACT same code works as an ASP.NET, but not as a console app.
Here is the non-functional console app code, followed by the WORKING ASP.NET
code. I've been pulling my hair out for 2 days on this. I'm doing this from
the same server, so it's not an SMTP Service config problem, because it's
from the SAME server. Any ideas? The error is:

Unhandled Exception: System.Web.HttpException: Could not access
'CDO.Message' ob
ject. ---> System.Reflection.TargetInvocationException: Exception has been
throw
n by the target of an invocation. --->
System.Runtime.InteropServices.COMExcepti
on (0x80040211): The message could not be sent to the SMTP server. The
transport
error code was 0x80040217. The server response was not available

Console App Code:
******************************
using System;
using System.Web.Mail;
namespace DailyKbEmail2
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
MailMessage msg = new MailMessage();
msg.From= "Click here to reveal e-mail address";
msg.To = "Click here to reveal e-mail address";
msg.Subject = "Hello";
msg.Body = "It works!";
SmtpMail.SmtpServer = "mail.kbAlertz.com";
SmtpMail.Send( msg );
}
}
}

Here is the WORKING ASP.NET code
*******************************************
using System;
using System.Web;
using System.Web.Mail;
namespace kbAlertz
{
public class test2 : System.Web.UI.Page
{
private void Page_Load(object sender, System.EventArgs e)
{
MailMessage msg = new MailMessage();
msg.From= "Click here to reveal e-mail address";
msg.To = "Click here to reveal e-mail address";
msg.Subject = "Hello";
msg.Body = "It works!";
SmtpMail.SmtpServer = "mail.kbAlertz.com";
SmtpMail.Send( msg );
Response.Write ("<BR>sent!");
}
}
}

Thanks!

Dave,

Just grasping at straws here, but are you running this code on two
different machines? That is, might the web server not be able to see the
SMTP server while your local dev box can?

Guha, Rahul

I was getting SAME error yesterday while my smtpServer didn't have
permission for relaying the email address ( a typical network issue ). I
tried with some different servers and finally got it working.
