Address This is the address space (domain) of the destination mail system You can type a domain (for example, Microsoftcom) or a subdomain (for example, eamicrosoftcom) Wildcards can be used to designate subdomains (for example, *com for all com domains or *microsoftcom for all subdomains of Microsoft com), but not to complete part of a domain name (for example, *softcom) For outbound mail to the Internet, type * Include all subdomains Select this check box to include all subdomains of the domain typed in the Address field If the address includes a wildcard (*), this check box is automatically selected Cost Exchange Server 2007 uses costs to determine the Send connector that has the best route to a particular address space The default cost is 1 The Send connector with the lowest cost is used However, unlike Exchange Server 2000/2003, Exchange Server 2007 does not check connector availability or fail over between connectors

Part III:

5 On the Network Settings page, select how to route outbound mail for the specified address space Here are the options: Use domain name system (DNS) MX records to route mail automatically This requires that Exchange be able to resolve Internet domains by using DNS The server s TCP/IP settings should be configured with valid DNS server(s) that can resolve Internet domains Name resolution failure will lead to the failure of mail delivery and messages being queued on the server Route mail through the following smarthosts This allows specifying the IP address or FQDN of specific external SMTP hosts, such as those of non-Exchange SMTP servers generally deployed in perimeter networks or those provided by a service provider

individual IP address or FQDN, clicking OK, and then clicking the Add button again to add another IP address or FQDN

6 If you selected the second option in the previous page to route mail to a smarthost, you are presented with the Configure Smarthost Authentication Settings page, shown in Figure 7-12 Select the appropriate mechanism to authenticate with

the smarthost(s) If you re using a service provider s SMTP servers (also referred to as relay servers or SMTP relays), contact the service provider for authentication settings Here are the options None (no authentication is used) Basic Authentication Exchange Server Authentication Externally Secured (for example, with IPSec) 7 On the Source Server page, verify the connector has the source servers that will be used to route outbound mail for this connector You can add Hub Transport servers as well as Edge Transport servers that are subscribed to the AD site 8 Click Next On the Configuration Summary page, verify all information is entered correctly 9 Click New to complete creation of new Send connector 10 On the Completion page, ensure the wizard completely successfully The Exchange shell command used to create the connector is displayed here 11 Click Finish to close the New SMTP Send Connector Wizard To create a new Send connector using the Exchange shell, use the following command:

New-SendConnector Name "Connector Name" Usage "Internet" AddressSpace "SMTP:*;1" DNSRoutingEnabled $true SourceTransportServers "HUB OR EDGE SERVER NAME"

SMTP connectors in Exchange Server 2000/2003 allow you to select a bridgehead server When selecting a bridgehead server, you are actually selecting from all available SMTP virtual servers on a server Exchange Server 2007 only allows you to select source transport server(s) All messages routed over the Send connector are sent to the source transport server(s)

The Exchange console allows modifying basic parameters of Send connectors such as the name, protocol logging level, FQDN, maximum message size, address space and cost, routing (DNS lookups or smarthost), and source transport servers These settings can be changed from the properties pages of Send connectors and have been covered in the preceding section To configure settings other than the ones mentioned, you will need to use the SetReceiveConnector command from the Exchange shell
