About Microsoft Exchange 2007 without an Edge Server
Microsoft® Exchange Server 2007 is designed as a high-end, scalable system,
with servers set up to work together in a large email network.
The recommended method for setting up Outbound Servers with Microsoft
Exchange 2007 is Private Outbound DNS. For more information, see “Microsoft
Exchange 2007/2010 (Private DNS Method)” on page 31.
Microsoft Exchange 2007 includes a concept that has not existed in previous
versions of Microsoft Exchange: different servers are assigned distinct, concrete
roles
. An Edge Server is one such role. The Edge Server connects all other
Exchange Servers to the Internet, and provides filtering and security.
This chapter gives details of how to set up Outbound Services for Exchange 2007
if you do not have an Edge Server. In this case, set up Outbound Services on a
Hub Transport server. If you do have Outbound Services, see the instructions in
the chapter “Microsoft Exchange 2007 with an Edge Server (Smarthost method)”
on page 83.
There is no need to increase the timeouts for Microsoft Exchange 2007 mail
servers. The default timeout settings are appropriate.
For Microsoft Exchange 2010, use the Private Outbound DNS method. For more
information, see “Microsoft Exchange 2007/2010 (Private DNS Method)” on
page 31.
