Hi Paul;
It is a remote possibility. You could try publishing it under a new Appeon name and see.
I have never used the Web Browser to send SMTP email as this would mean every client would be connecting to the email server. Instead, I use my STD Web Service framework's support for SMTP to accomplish this task. So I can't advise you on the browser side if it even does work as I've never tried it using my STD Integrated Framework. I use my client side framework's SMTP all the time in native Win32 applications.
