I understand from that TLS is enabled by default for server-to-server traffic.

I, also, read "SSL certificates are installed by default in Exchange Server 2007, enabling broad use of SSL and TLS encryption from clients such as Outlook Web Access and other SMTP servers."

4. Is there a good step-by-step for forcing TLS exchange 2007 to exchange 2007 encryption?
