Please note that CDONTS has been deprecated and is available only on our Windows 2000 servers. If your site is hosted on a Windows 2003 or 2008 server please have a look at CDOSYS. Below is a simple CDONTS example written in ASP.
Set objMail = Server.CreateObject("CDONTS.NewMail")
objMail.From = "email@example.com
objMail.Subject = "CDONTS Samples"
objMail.To = "firstname.lastname@example.org
objMail.Body = "This is a sample message sent using CDONTS."
Response.write("Mail was Sent")
'You must always do this with CDONTS.
set objMail = nothing
Modify the values above as appropriate then copy the code above into a file called cdontstest.asp on your site. When that's done go to http://www.yourdomain.com/cdontstest.asp
If the test was successful the screen should show "Mail was Sent" and email@example.com should receive the email test.
