I've used CDONTS for years, even though it hasn't been included in a Windows Server release since NT4. Anytime I needed to send mail, I'd copy over CDONTS.dll, register it then use my old CDONTS code. Not sure why I resisted it for so long.. I think the weird Configuration Fields were too odd to accept. But I've finally accepted them.. about 3 good years after ASP went out of style. Here's a less-than-timely code snippet:
This is the sound of settling.
Set objCDO = CreateObject("CDO.Message")
objCDO.Subject = "Update from Web App."
objCDO.From = "Web App <webapps@me.com>"
objCDO.To = "yomomma@gmail.com"
objCDO.TextBody = "Hello," & vbCrLf & vbCrLf & "A new order has been placed by " & userName & "."
objCDO.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2 'cdoSendUsingPort (1 = local, 3 = Exchange)
objCDO.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "mail.me.com"
objCDO.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
objCDO.Configuration.Fields.Update
objCDO.Send
set objCDO = Nothing
