Sending Mail using CDONTS and IIS4

Hi All..
I am using Following Code to send an email to the user... No Error but the mail is not being sent...
I am new to this.. so plz help me even if i am being so stupid...

VB Code:

Dim myMail
    Set myMail = CreateObject("CDONTS.NewMail")
    myMail.From = "[email protected]"
    myMail.To = "[email protected]"
    myMail.Subject = "Your account information"
    myMail.Body =   firstname & " " & lastname & vbcrlf & "You  have been registered under UserName: " & loginname & " and Password: " & upass
    myMail.Send
    Set myMail = Nothing

One more point.. I am behind a proxy server.. IIS is running on my machine..should i do soething with Default SMTP Server?

Anyone with some IDEA?
Please!!!!!!!!!!!11

How is the e-mail sent using CDONTS supposed to be sent??

- Does it get sent via Exchange (in which case there should be an error log / event reported on the server somewhere).
- Does it get sent via an SMTP servers (in which case do you have access for you or your computer to relay messages through the server)

Thanx God.. i have got a reply...
I have to send mail thru SMTP....
Now what should i do?
Waiting for your feedback..
Thanx man..

An SMTP Server will need to take your SMTP formatted e-mail message and relay it onto the next SMTP server in the chain to delivery to the end user.

If the SMTP server you are communicating with doesn't like you (in a computer sense) then it will not accept the SMTP message and will refuse to relay it for you.

For example, the SMTP server may refuse your IP address, your computer name, your logon name or the .FromAddress in your e-mail.

How CDONTS identifies which SMTP server it is talking to, I am not sure. It might be DNS or it might be in the configuration files somewhere.

Have you installed and configured the SMTP server component of IIS?

I have installed SMTP.. but just wondering what/how to configure?

I think it is an NT Service. Scroll through the services and see if there is an entry for SMTP (I don't have an NT Server machine available so cannot check).

SMTP Service is up and running... It just doesn't send the mail

I think... it's been a while..... but, I think you have to give it the SMTP IP address....

Hope these links provides some clue ...
