unable to send email error- 0xC00402C7.

Question

Hi

I am trying to send a simple email through the following code:

protected void email_Click(object sender, EventArgs e)
{        
   System.Net.Mail.MailMessage msgMail = new System.Net.Mail.MailMessage();
   msgMail.From = new System.Net.Mail.MailAddress("[email protected]");
   msgMail.To.Add(new System.Net.Mail.MailAddress("[email protected]"));
   msgMail.Subject = "Request:Joing into the  myitem.Title.ToString()";
   msgMail.IsBodyHtml = true;
   string strBody = "test mail";
   msgMail.Body = strBody;
   System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient();
}

I have installed the SMTP server on my local machine. The folders in mail root have all the permissions.

My mails stay in the Queue folder for sometime and then they go to the Badmail folder. I am receiving the following error:

Unable to deliver this message because the follow error was encountered: "This message is a delivery status notification that cannot be delivered.".

The specific error code was 0xC00402C7.

The message sender was <>.

The message was intended for the following recipients. [email protected]
