You are a messaging professional. Your company uses a Microsoft Exchange Server 2003 messaging system.
The company plans to upgrade from the Exchange Server 2003 computer to a Microsoft Exchange Server 2007 computer.
The company uses a third-party SMTP gateway server that is deployed in the perimeter network. The third-party SMTP relays Internet e-mail messages to the Exchange 2003 environment.
The company will retain the third-party SMTP gateway server and will not deploy an Exchange 2007 Edge Transport server.
You configure the SMTP gateway server to use the fully qualified domain name of a Hub Transport server as the relay server for the internal SMTP domain.
You need to ensure that inbound e-mail messages will flow through the SMTP gateway servers to an Exchange Server 2007 Hub Transport server.
What should you do?
A.
Modify the third-party SMTP gateway server to use the same DNS servers as the Hub Transport server.
B.
Modify the Hub Transport server to use the same DNS server as the third-party SMTP gateway server.
C.
Modify the Default <Servername> receive connector on the Hub Transport server to allow anonymous
SMTP connections.
D.
Create an e-mail address policy. Configure this policy to apply to all recipient types and specify the e-mail
domain used by the Exchange Server 2007 users.
