Just a addition.
The edge transport server is specifically tailored to be used as the
permiter relay. It is installed as an standalone server , so it can be
put in a DMZ without having to open ports to domain controllers or
hosting AD in the DMZ. It uses a ADAM implementation where userinfo is
stored, which is replicated one-way by an internal Hub transport
server. It also contains several transport agents which rewrite
message content, do antivirus, antispam etc. The antispam agents can
be installed on a hubtransport using the script I mentioned earlier.
For a simple Exchange setup you can safely go with the single hub
transport server facing the internet, but be aware of the config I
mentioned. (inbound security, dsn's, maybe some content rewriting etc)
