With the creation of Send Connectors and Receive Connectors, several usage types are
possible, which specify the authentication mechanism and permission groups to be associated with that
connector. As you will recall, by default two explicit Receive Connectors are created with the installation
of the Hub Transport server role and no explicit Send Connectors are installed; however, an implicit
Send Connector exists to enable Hub Transport servers in the same Active Directory site exchange email
messages. Hence no explicit Send Connectors are required to configure mail flow between Hub
Transport servers in the same Active Directory site. Finally, we briefly reviewed the concept of accepted
domains and email address policies.
Configuring the Mailbox
Server Role
The Mailbox role is at the heart of the server roles. Mailbox and public folder data is stored on
the Mailbox role. Other processes, such as managed folders and address book generation run
on the Mailbox role. Unlike previous versions, the mailbox server does not send or receive mail
without going through a hub transport.
The Mailbox role can be configured for high availability using traditional clustering or a few new
options. High - availability options are discussed in Chapter 12 .
