Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

 

Applies to: Exchange Server 2007

Use the Network Settings page on the New SMTP Send Connector wizard to specify the servers from which e-mail messages are sent.

You can use the Domain Name System (DNS) to determine how to route all outbound mail through the connector. Alternatively, you can specify a smart host to which the connector routes all mail.

If you route mail to the Internet through an Internet service provider (ISP), contact your ISP to determine what IP address or fully qualified domain name (FQDN) to use for the smart host. After you have the IP address or FQDN, make sure that the IP address or FQDN meets the previous requirements.

  • Use domain name system (DNS) "MX" records to route mail automatically
    This option is available only if you selected a usage type of Custom, Partner, or Internet on the Introduction page. To use DNS to route outbound mail, select this option. The connector uses DNS to resolve the IP address of the remote Simple Mail Transfer (SMTP) server. Then it delivers the mail.

    If you select this routing method, verify the following:

    • Can your DNS server successfully resolve names on the Internet?

    • If you have used the Set-TransportServer cmdlet to configure an external DNS server that differs from the one specified on the network connection, can this external DNS server resolve names on the Internet?

  • Route all mail through the following smart hosts
    This option is available only if you selected a usage type of Custom, Internal, or Internet on the Introduction page. To use a smart host to handle DNS resolution and deliver the mail, select this option, and then click Add. You can specify either of the following options in the window that appears:

    • IP Address   To identify the smart host by IP address, select IP Address. Then type the IP address in the text box as in the following example: 192.168.100.1.

    • Fully qualified domain name (FQDN)   To identify the smart host by FQDN, select Fully qualified domain name (FQDN). Then type the FQDN in the text box. FQDN is a DNS name that has been stated to indicate its absolute location in the domain namespace tree. For example, type smarthost.contoso.com.

    Note

    You can set up a server that is running Exchange Server as the smart host. However, make sure that the smart host Exchange server is not one of the Exchange servers to which this Send connector is sourced in the Source Servers tab.

    To edit the settings of a smart host, select the smart host and then click Edit.

    To remove a smart host, select the smart host and then click Remove icon.

  • Use the External DNS Lookup settings on the transport server
    Select this option to use the external DNS servers list to resolve names on the Internet.

    Important

    Verify that you have configured the external DNS servers list by using the Set-TransportServer cmdlet.
