Email and Server Security and Exchange 2016 : smtp relay and Edge roles
In admin guide, on page 34, it is specified "Do not specify the server where the Edge role is
installed as Internal SMTP Sender."
Our internal Exchange servers have all the Edge role. Should we specify their IP address ?
This sentence is not clear also : "Note: If the organization has Exchange Edge and
Hub servers, the server with the Hub role installed
should be added to the Internal SMTP Sender on
the server where the Edge role is installed."
Can anyone explain these things ?
