Sending Mail From ASP With CDONTS.NewMail Object

I use the following code to send email from an ASP page:

<%
Dim objSendMail
Set objSendMail = Server.CreateObject("CDONTS.NewMail")

objSendMail.From = "abc@abc.com"
objSendMail.To = "abc@abc.com"
objSendMail.Subject = "Form Results - Get a Quote"
objSendMail.Body = "This is the Body text of this test mail."
objSendMail.Send
Set objSendMail = Nothing
%>

Of course, the the email addresses above are real on my ASP page.

After the above code is executed, I don't receive any email.

What is the problem?
