Quote: CDO is pretty old now so assume that is an example of an app that doesn't support latest security standards.

What are the alternatives to create a script or batch file to send email? I can only get CDO to work with servers that support SSL set to false. As soon as I set SSL to true it fails to connect and I know at least one server I tested with definitely supports SSL on port 465 and startTLS or ports 25 and 587.
