I currently have a windows server 2012 R2 server setup with IIS and configured it as an open SMTP Relay. Our security team wants us to lock it down to use Secure SMTP where only devices or applications that can do authentications is able to relay mail off of this relay server.
Since everything is in an active directory environment, on the access tab> authentication I selected integrated windows authentication. On the delivery tab, I click on outbound security and select integrated windows authentication and put the service account username and password. On the security tab, I also added the service account username to it.
If I setup an application to point to this relay server and have the application setup to perform SSMTP, I still do not get the email in my inbox nor do I see the email message stuck in the current session.
