asp.net : c#.net : difficulty in sending emails

[vishalgupta]

when i use the code :

private void Report(int var)
    {
        var++;
        String ToEmail = "";
        String FromEmail = "";
        String Bdy = "";
        ToEmail = System.Configuration.ConfigurationManager.AppSettings["EmailReportTo"];
        FromEmail = System.Configuration.ConfigurationManager.AppSettings["EmailReportFrom"];
        Bdy = var.ToString();
        try
        {
        SmtpMail.Send(FromEmail, ToEmail,"value",Bdy);
        Response.Write("Your Email has been sent sucessfully");
        }
        catch (Exception exc)
        {
        Response.Write("Send failure: " + exc.ToString());
        }
    }
 

the output shows that the email has been send but no email is received on the ToEmail address

when i use :

 
private void Report(int var)
    {
        var++;
        String ToEmail = "";
        String FromEmail = "";
        String Bdy = "";
        String ServerName = "";
        ServerName = System.Configuration.ConfigurationManager.AppSettings["SMTPServerName"];
        ToEmail = System.Configuration.ConfigurationManager.AppSettings["EmailReportTo"];
        FromEmail = System.Configuration.ConfigurationManager.AppSettings["EmailReportFrom"];
        Bdy = var.ToString() ;
        System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
        message.To.Add(ToEmail);
        System.Net.Mail.MailAddress address = new System.Net.Mail.MailAddress(FromEmail);
        message.From = address;
        message.Subject = "value"; 
        message.Body = Bdy;
        System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient(ServerName);
        smtp.Port = 25;
        try
        {
            smtp.Send(message);
            Response.Write("Your Email has been sent sucessfully");
        }
        catch (Exception exc)
        {
            Response.Write("Send failure: " + exc.ToString());
        }
 
    }
 
 

it shows the exception :
Send failure: System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: 5.7.1 Unable to relay for [e-mail] at System.Net.Mail.SmtpTransport.SendMail(MailAddress sender, MailAddressCollection recipients, String deliveryNotify, SmtpFailedRecipientException& exception) at System.Net.Mail.SmtpClient.Send(MailMessage message) at _Default.ReportSpamBot(Int32 var)

somebody please help as to how should i send the emails??

It sounds like Yahoo is viewing the email you are sending as SPAM. Yahoo then returns an email telling you that the mailbox in unavailable. Try turning off SPAM control in Yahoo and try sending again.
