CDOSys- SendUsing config value is invalid

I am trying to write an email form using cdosys, but I am getting the following error
-The "SendUsing" configuration value is invalid

It seems like everybody in the world is having this problem. I've looked through a ton of post and tried everything. Following is my code:

set objMail=Server.CreateObject("CDO.Message")
set cdoConfig = Server.CreateObject("CDO.Configuration")
With cdoConfig.Fields
.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "mysmtp.server.com"
.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
.Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = "username"
.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "password"
.Update
End With

With objMail
.SUBJECT = "Help Form"
.SENDER = "[email protected]"
.TO = "[email protected]"
.HTMLBody = "Email body"
.Send
End With
set objMail = Nothing
set cdoConfig = Nothing


Unless I am missing something obvious, I think it has something to do with smtp authentication. Any help would be greatly appreciated.

I think you have to set the smtp server to be "localhost"

I can't use localhost. I don't have smtp installed on the server I am working off of. I am bouncing it off a valid smtp mail server and authenticating with a valid sign on (username and password).

 

this worked for us. put this line in:
with MyMessage
.to = blah blah blah
.from = .....
.Fields.Add(http://schemas.microsoft.com/cdo/configuration/smtpauthenticate, 2)
end with

apparently this forces NTLM authentication when relaying through exchange virtual smtp server, or IIS virtual smpt server.
0=basic
1=something else
2=NTLM authentication
if this works for you, spread the word through other forums, cuz we spent tonns of time trying to figure this error out.
