Hi,
I want to secure all my inbound\outbound external mails by TLS. Currently, we have a IIS SMTP relay in DMZ zone which forwards\accepts all external inbound\outbound mails from Internet and HUB servers.
What is the best way to do this?
1.Install a 3rd party certificate on SMTP virtual server and enable TLS
2.Install EDGE in secure it with 3rd party certificate and enable TLS
