You are the messaging engineer for your company.

Your company is transitioning from Microsoft Exchange Server 2003 to Exchange Server 2007. 3,000 mailboxes have been moved to the Exchange Server 2007 Mailbox servers. 3,000 mailboxes are still hosted on the Exchange Server 2003 servers.

Your company recently registered an additional domain name fourthcoffee.com. You have updated the DNS servers with the appropriate records.

You need to ensure that:
All users are configured with a fourthcoffee.com e-mail address.
The Exchange organization accepts messages for the fourthcoffee.com domain.

Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A.
From the Exchange System Manager, create a recipient policy for the fourthcoffee.com domain. Apply the policy to all Exchange recipients.

B.
From the Exchange System Manager, create a custom address list. Specify the * LDAP filter to the address list.

C.
From the Exchange System Manager, create a new Internet Message Formats domain for the fourthcoffee.com domain.

D.
From the Exchange Management Console, create a new accepted domain for fourthcoffee.com.

E.
From the Exchange Management Console, create a new Receive connector. Enable the Exchange Server authentication mechanism for the new Receive connector.

Explanation:
In Exchange 2003, there are two kinds of Recipient Policies: email address and mailbox manager policies. Email address policies combined the Exchange 2007 concepts of EAP and accepted domains. The ESM GUI to configure any domain to be stamped with recipient email addresses also has the option to establish this domain as authoritative:

There are several problems with this combined Recipient Policy format: If a domain is specified for such a policy but not marked as authoritative, mail sent to recipients with these domain addresses wont be correctly routed inside the Exchange organization. This is an invalid scenario, but one not blocked by the ESM GUI. Relay domains, on the other hand, are managed thru the Connector GUI, a location completely different from that above:

In Exchange 2007, Recipient Policy is separated into two concepts: Email Address Policy (EAP) and Accepted Domains.

EMC > Organization Configuration > Hub Transport > New Accepted Domain

EAP defines an email proxy address stamped onto recipient objects. Accepted domain defines an SMTP namespace for which the organization routes mail. Authoritative and relay domains are managed together in the same panel. Any accepted domain added to the system can be linked to an EAP, so itll generate appropriate recipient mail addresses. Likewise, every EAP must link to an established accepted domain, so mail dispatched to addresses defined by this policy is properly routed by the 2007 transport servers.

The EAP wizard provides the console GUI to choose the accepted domain for a newly created address policy. Only accepted domains defined in the organization can appear on this list:
