   Hi all,

             I'm having problem in email service,When i tried send a bulk mail from my web page, it gives the following error  "Unable to read data from the transport connection: net_io_connectionclosed" . I tried in many ways to correct the problem by changing the config file email settings & IIS -> SMTP Setting and all.. Still now i have the same problem.. If Anyone know the solution for the above problem, please let me know...

  My coding for sending mail

  ---------------------------------------

   Private Sub callmail(ByVal toadd As String, ByVal f As Integer) 
   
  
          Dim msg As New MailMessage()
          Dim urlpath As String
                    
          msg.From = New MailAddress(ConfigurationManager.AppSettings("DefaultMail"))
          msg.to.add(New MailAddress(ConfigurationManager.AppSettings("DefaultToMail")))
          msg.Bcc.Add(toadd)       
          msg.Subject = txtsub.text
          msg.Body = txtmsg.text
          msg.IsBodyHtml = True '.BodyFormat = MailFormat.Html        
          Dim smpt As New  System.Net.Mail.SmtpClient(ConfigurationManager.AppSettings("DefaultSMTP"))
          smpt.ServicePoint.MaxIdleTime = 1
          smpt.ServicePoint.ConnectionLimit = 1
         smpt.Send(msg)
        'Response.write (txtmsg.text)
      End Sub
