To use it, you must first have it installed on your server. As an example, you could use it in the following way to send an email from an ASP:

<% Option Explicit
Dim objCDOMail
'Initialise CDONTS object
set objCDOMail = Server.CreateObject("CDONTS.NewMail"
objCDOMail.From = "from address"
objCDOMail.To = "to address"
objCDOMail.Subject = "subject"
objCDOMail.Body = "body text"
'Send mail
objCDOMail.Send
'Remove object assignment
set objCDOMail = Nothing
