Does anyone know how to confirm if an email was sent successfully?

  What exactlty is the version of the framework and Visual Studio you are using
  
  

• Phan

  You don't need to wait.

  The .NET 2.0 Redist (framework) and sdk are free :-)
  and the SDK is also free. Download, and just set the path to the
  VBC compiler and you are good to go. You can easily develop the apps
  with just a good editor and fx/sdk

  Try http://msdn.microsoft.com/net

  Hey Durgaprasad Gortion,
   
  Could you try something for me reguarding the DeliveryNotificationOptions...
  
  I've successfully been able to impliment the option and get a Delivery Receipt.
  
  Though if I send more then one message I only get the Delivery receipt for the first message sent.
  
  Any subsequent message does not get a delivery receipt. 
  
  The Connection to the SMTP Server stays connected even after the SMTPClient & MailMessage Objects go out of scope and a Manual Garbage Collections Happens.  I'm guessing this is to allow multiple messages to be send without opening and closing the SMTP connection each time.
  
  Though It seems that I only get the one Delivery Receipt for the Connected Session.
  
  I ran a Protocol Trace and Noted the on the RCPT TO Command sent to the SMTP Server only had the NOTIFY=STATUS for the First message. All the others did not have it.
  
  Could you Verify this   I could send you my Test app if you like. I've included the Code of my SendEmail Function
  
  Thanks,
    Scott<-

  Thanks for all your wonderful help. I will come back to this issue after I receive my VS2005 Pro version.
  
  Thanks again
  

• Sam Lowry139354

  Oh, forgot to mention I'm using
  VS2005 8.0.50727.42 (RTM.050727-4200)
  .NET Framework 2.0.50727
  
  Thanks,

  [Flags]

  public enum DeliveryNotificationOptions {

  None = 0, OnSuccess = 1, OnFailure = 2, Delay = 4, Never = (int)0x08000000

  }

  please try the

  DeliveryNotificationOptions property on the MailMessage

  
  
  

• Praxy

  Durgaprasad:
  
  Thanks for your patient.
  
  Since I have not gotten the Visual Studio 2005 Proffessional version I ordered from Amazon I'm still using the Beta #2.
  
  
  

• Pachacutec

  Durgaprasad Gorti :
  
  Sorry for the newbie question:
  
  But how would you use these enums in VB2005 for setting a boolean variable to True if sent OK and false if otherwise
  
  Thanks
  
  
  

• Martin Platt

  Its an enum

  So set MailMessage.Deliver.... = Deliver...Success

  Imports System.Net

  Imports System.Net.Mail

  Module Module1

  Sub Main()

  Dim msg As New MailMessage

  Dim client As New SmtpClient("smtpserver")

  msg.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess

  msg.To.Add(New MailAddress("x@y.com"))

  msg.From = New MailAddress("x@y.com")

  msg.Subject = "test"

  msg.Body = "Test"

  client.UseDefaultCredentials = True 'Optional

  client.Send(msg)

  End Sub

  End Module

  
  
  

• TGAR

  No matter how hard I try intellisense will simply refuse to to show any of these
  
  

  msg.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess
  

  
  I paste this code in a module and could not get anything resembling "DeliveryNotificationOptions" in Intellisense after typing msg.
  
  this is the code:
  
  

  Imports System.Net

  Imports System.Net.Mail

  Module Module1

  Sub Main()

  Dim msg As New MailMessage

  Dim client As New SmtpClient("smtpserver")

  msg.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess

  'msg.To.Add(New MailAddr...

  End Sub

  End Module

  Sorry for my stupidity I just don't get it.
  
  What do you mean by this:
  
  

  So set MailMessage.Deliver.... = Deliver...Success
  
  Intellisense is not giving me any member of this type : MailMessage.Deliver
  

  
  

• Leo Fi

  I belive this is added post Beta2.
  So no wonder you are not seeing this in intellisense

  Use the VS2005 RTM bits or just use the free redistributables and sdk.
