Since you have a server available already, you could install an SMTP relay on the Fusion server that accepts mail from localhost:25 and sends it via TLS/SMTP AUTH to the appropriate host.

Most?mail servers use TLS and other forms of authentication. The mail server authenticates the username and password and then relays it to the SMTP server. The SMTP server will only allow packets sent from a whitelist.? If you don't have them put the Crestron IP address in that whitelist you will never be able to send mail.

We came across this with Fusion. We were not doing exchange integration and wanted to send mail. Fusion only supports SMTP on port 25. There is no way to change it or enable higher forms of authentication. The only work around was to add the Fusion server to the whitelist and allow it to communicate to the mail relay.
