CDOSYS HTTP 500 error

[Frggs]

I am trying to familiarise my self.. so please be patient! a total nubie….

The following is copied from http://www.w3schools.com/asp/asp_send_email.asp

I am working my way through the tutorials… everything works so far… until I try this….
Examples using CDOSYS
Sending a text e-mail:
<%
Set myMail=CreateObject("CDO.Message")
myMail.Subject="Sending email with CDO"
myMail.From="mymail@mydomain.com"
myMail.To="someone@somedomain.com"
myMail.TextBody="This is a message."
myMail.Send
set myMail=nothing
%>

I am trying this on a local machine with Vista Ultimate and IIS 6 installed with these features

But with myMail.Send this results in HTTP500 internal server error

What am I missing?

Use following and provide data according to your server settings:

'#Text body email NOT html
set objMail = Server.CreateObject("CDO.Message")

objMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
objMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "info@yourdomain.com" '#smtp address
objMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25'#smtp port
' objMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1

' objMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = "verfiyemail@yourdomain.com" '#validation email
' objMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "password" '#validation password

objMail.Configuration.Fields.Update

objMail.From = "Zeeshan Dar <info@irealtysolution.net>" '#sender email
objMail.To = "receiver@email-address.com" '#receiver email
objMail.BCC = ""

objMail.Subject = "Email subject" '#email subject
objMail.TextBody = "Email body" '#message body

objMail.Send '#send email
set objMail = nothing
