UPGRADING TO LOTUS NOTES 6 AND LOTUS DOMINO 6

How Lotus Domino 6 replaces the Domino 4.6 MTA
When you enable a Domino 6 server to send messages over SMTP outside the local Internet domain (configured in the Server Configuration document), the server does not require Foreign SMTP Domain and SMTP Connection documents because the server can connect by TCP and route mail by SMTP. However, if you have existing SMTP Connection documents, Lotus Domino 6 follows the Foreign SMTP Domain and SMTP Connection documents for SMTP mail routing.

The server can use a relay host as needed and can make connections using DNS or using a hosts file. The server uses the router to route mail over SMTP and to perform conversion between Notes format messages and MIME format messages. Thus, the Domino 6 server replaces the outbound services of the MTA.

When you enable a Domino 6 server to listen for inbound SMTP connections (configured in the Server document), the server performs the same functions as the inbound MTA services. Inbound messages are stored in MAIL.BOX and transferred or delivered by the router. MIME messages are stored in that format and routed over either Notes RPC or SMTP to their destination. If needed, the router converts between MIME and Notes format messages.
