How to: Windows Vista SMTP Server - Using CDO.Message

Author: Robert Martim | Posted: 22. June 2009 21:38 2
I had been using CDO object with Windows XP for a while and the code always ran without a problem, as long as the SMPT server was installed and properly set up. That was easy to do. As I moved the code to Windows Vista, I come to realize that my code no longer worked. I tried installing the SMTP Server on Windows Vista, but that was pointless since it is no longer available. I was having some trouble believing it was not there given that I used Windows Vista Ultimate, but fellow MVPs Bernard Cheah (http://www.iis.net/ http://msmvps.com/blogs/bernard/) and Gary VanderMolen confirmed my worries. Ron de Bruin, a fellow Excel MVP, also took part in the conversation about the issue. He also has an article on the subject which can be found here: http://www.rondebruin.nl/cdo.htm

According to Gary, this is pretty much useless anyway given that most ISPs nowadays block all port 25 traffic except to their own SMTP server.

In that case, I had to adapt things slightly so that I could route my emails through my SMTP Server. Nonetheless, I can still use Vista to route the email to a local pickup folder so that I can at least test things.

Here’s how it is done (uncomment the code to test locally):

Sub CDOTest_OnVista()
    Dim oCDO                    As Object
    Dim oCDOConfig              As Object
   
    Const c_sUsername           As String = "Your_Username_Goes_Here"
    Const c_sPassword           As String = "Your_Passoword_Goes_Here"
   
'   if you are using localhost to route the e-mail, you need to define
'   a pickup folder. In this case, I use: "C:\inetpub\mailroot\Pickup"
    Const c_sPickupFolder       As String = "C:\inetpub\mailroot\Pickup"
    Const c_iSMPTPort           As Integer = 25

   
    Dim iSendUsing              As Integer
    Dim sSMPTServerName         As String
   
   iSendUsing = 2      'remote host
'   iSendUsing = 1      'localhost

'   Define the SMTP Server here. "localhost" for using Vista's localhost
'   as the server. In the case below, you should use your own server.
'   sSMPTServerName = "localhost"
    sSMPTServerName = "Your_SMTP_server_goes_here" 'e.g.: smtp.youcompanyname.com
   
    Set oCDO = CreateObject("CDO.Message")
    Set oCDOConfig = CreateObject("CDO.Configuration")
   
    With oCDOConfig.fields
        .Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = iSendUsing
        .Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = sSMPTServerName
        .Item("http://schemas.microsoft.com/cdo/configuration/username") = c_sUsername
        .Item("http://schemas.microsoft.com/cdo/configuration/password") = c_sPassword
        .Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = c_iSMPTPort
        .Item("http://schemas.microsoft.com/cdo/configuration/smtpserverpickupdirectory") = c_sPickupFolder
    End With

    With oCDO
        Set .Configuration = oCDOConfig
            .From = Sender@Email.com
            .To = Receiver@Email.com
            .Subject = "Test Message"
            .Configuration.fields.Update
            .Send
    End With
   
    Set oCDOConfig = Nothing
    Set oCDO = Nothing
   
End Sub

I want to have additional information using HTML, Java, CSS for my blog site. And finding what themes are applicable to my blog site and choosing what is the best version of blogengine for my blog site.

I am not sure what this has to do with this post... however, WordPress has lots of themes. I don't think you need (or want) to learn HTML, Java or CSS for that matter.
