The following configuration options will help ensure better fidelity when routing mail between Lotus Domino servers and servers running Microsoft Exchange Server 2007.

Domino Configuration

Verify that the configuration document for the server(s) that will route mail to Exchange has the Message content field set to from Notes to Plain Text and HTML, which is not the default setting. This field is under the MIME/Outbound Conversion Options tab. Figure 1 displays this setting.

For details about how to configure Lotus Domino servers to support SMTP mail routing, see the Domino Administration Help database (available in the Lotus Notes client's \Help directory under the Notes \Data directory) or access the information at the IBM Web site.

Exchange Configuration for Lotus Domino Interoperability

Details about configuring Exchange 2007 are available in the Exchange 2007 Help.

Receive Connector Configuration

Create a new remote domain. Be sure to set the organizational parameter to Exchange rich-text format-Never use for e-mail that routes to Domino. A SMTP Remote Properties dialog is displayed in Figure 2.

Create a new Receive Connector for mail routing from a Lotus Domino server, which routes all mail from the Lotus Domino domain via SMTP.

  • When prompted to Select the intended use for this Receive Connector, leave the default setting of Custom.

  • On the Local Network settings page, accept the defaults (all available).

  • On the Remote Network settings page, delete the default entry (all available) and click Add. Enter the IP address for the Lotus Domino server that will route mail to Exchange via SMTP. Figure 3 shows an entry for a Lotus Domino server.

  • On the SMTP Connector Properties dialog box's Permission Groups tab, verify that Anonymous users and Exchange servers are selected. Additional options may also be selected. Figure 4 displays the available options for the Permission Groups tab.

  • On the Authentication tab, verify that Externally Secured (for example, with IPsec) check box is selected.

Send Connector Configuration

Create a new Send Connector to route mail to a Lotus Domino server. This server will then route e-mail to the appropriate Lotus Domino server using information in the Domino Directory.

  • When prompted to Select the intended use for this Send Connector, accept the default setting Custom.

  • When prompted to specify an Address Space, add the SMTP domain that is used for the Domino users and servers. If applicable, select the Include all sub domains check box. Figure 5 shows the configuration for the contoso.com domain used by the Domino servers and users in the environment. The wildcard (*) indicates that mail addressed to any subdomain of contoso.com (such as domino.contoso.com or boston.contoso.com) will also be routed to Domino.

  • On the Network settings page, if a DNS server is used to route mail directly to the Domino server, accept the default setting Use domain name system (DNS) "MX" records to route mail automatically. This setting is typically configured when all mail routing to Domino is addressed to a subdomain such as domino.contoso.com. If a subdomain isn't used in your environment, select the Route mail through the following smart hosts option, and then add the IP address or Fully Qualified Domain Name (FQDN) for the Lotus Domino server that will accept mail from Exchange. Figure 6 displays a configuration with a specific Lotus Domino server's IP address listed.

  • Set Smart Host authentication to None.

  • On the Source Server page, add any servers that are running Exchange 2007 that route mail to Lotus Domino via SMTP.
