Sending an email via vb

I wrote a vb script to back up a few files on my pc.

I want it to send me and email when it is done telling me that the files have been backed up.

I an using the following code and I am getting errors

Dim objMessage
Set objMessage = CreateObject("CDO.Message")
If Err.number <> 0 then
WScript.Quit Err.Number
End If
objMessage.Subject = "Test Message"
objMessage.Sender = "[email protected]"
objMessage.To = "[email protected]"
objMessage.TextBody = "This is some sample message text."
objMessage.Send

Error: The "SendUsing" configuration value is invalid.

What do I have to do to fix it. It works fine when I do this via asp on a web page but when I try to do the same thing via a script file, I get that error.

Is there something else I have to add?

Thanks,
DL

Seems that you need to specify the smtp server?

VB Code:

SmtpMail.SmtpServer = "mail.your-domain.com"
 
By default, if SmtpMail.SmtpServer is not set, System.Web.Mail is supposed to use localhost as the default property. 
However, for some reason this doesn't appear work. If you are using the local SMTP Service to send emails, you may try the following values: 
 
"127.0.0.1" 
"localhost" 
"the_machine_name_here" 
"the_real_dns_name_here" 
"the_machine_IP_Address_here" 
That should fix it.

From this site here - http://www.systemwebmail.com/faq/4.2.2.aspx

Why not just ShellExecute "mailto: your address"? That would open the default e-mail client (Eudora, Outlook, Outlook Express, or whatever the user has as their default client) to send the message.

Because if the system doesnt have a email client it will brng up the Open With dialog box. Also, with Outlook it will invoke the Security Prompt dialog window before it is Sent. ;)
