Look up ASPMail
http://www.serverobjects.com

If you don't want to purchase software, you can try usin CDONTS, but I don't much care for it. Google CDONTS, and you'll find plenty of examples. I highly recommend ASPMail though. It's all I use in all of my implementations.

Sub SendEmail(from, to, subject, msg)
Dim objMail
Set objMail = CreateObject( "CDONTS.Newmail" )
objMail.From = from
objMail.To = to
objMail.Subject = subject
objMail.Body = msg
objMail.Send
Set objMail = Nothing
End Sub

CDONTS is obsolete component and it's better to use CDOSYS to send an email from an ASP page.
