PLANNING
HCL Domino® interoperates with other mail servers and systems through its support of Internet standards and message transfer agents (MTAs), for example, Microsoft™ Exchange. Domino can exchange mail with other SMTP servers and route mail to and from Microsoft Exchange and other systems through the MTAs. Additional third-party tools are available to provide interoperability with and gateways to other mail systems.
If you have some users who use Microsoft Exchange, you need at least one Exchange server running the Exchange message transfer agent (MTA) to connect your Domino system to the Microsoft Exchange system.
If you have users in the local Internet domain who are not listed in the Domino Directory, set up a smart host so the router can forward messages for users in other local mail systems.
