I've never really attempted to configure TLS on any of our customer Exchange servers before.
I've read this:
But I'm a bit confused on what certificates are required.
We have multiple hub transport servers, sending and receiving emails to/from the Internet.
Are we able to enable TLS if there is a smart host in the way?
If we are sending from multiple hub transport servers, do we need a cert for each of these? or can these be covered by a single cert?
Any help is appreciated!
