email - SMTP configuration SendUsing configuration value is invalid with ASP-Classic

Question

I'm trying to get an email sent using ASP classic, and am having trouble with SMTP configuration.

The error:

CDO.Message.1 error '80040220' The "SendUsing" configuration value is invalid.

The Code(for the email itself):

Set objMsg = Server.CreateObject("CDO.Message")  
objMsg.From     = "name@name.com"  
objMsg.To       = "themetatron@gmail.com"  
objMsg.Subject  = "Procurement Ally Update"  
objMsg.TextBody = strBody 

The Code I tried to configure with (pt 1):

sch = "http://schemas.microsoft.com/cdo/configuration/"  
Set cdoConfig = CreateObject("CDO.Configuration")   
    With cdoConfig.Fields   
        .Item(sch & "smtpserver") = "127.0.0.1"   
        .update   
    End With   

That didn't work, so I tried:

objMsg.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "localhost"  
objMsg.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25  
objMsg.Configuration.Fields.Update 

That also didn't work.

(Yes, I didn't show it, but at the end there's a call to objMsg.Send)

As far as I can tell, the local boxes SMTP service is running and ready to do its duty.

Can anyone help?

If you are specifying an smptserver, be sure to set your 'sendusing' field to 2 (or cdoSendUsingPort) as well:

objMsg.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
objMsg.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "localhost"
objMsg.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
objMsg.Configuration.Fields.Update
