In this example, Acme has three IBM® Lotus® Domino™ servers and a third-party SMTP host in the local Internet domain that handles mail for some users. All users have entries in the Domino Directory. When a user sends mail to another user in the acme.com domain, the Domino server looks up the recipient in the Domino Directory. If the recipient has a mail file on one of the Domino mail servers -- Mail1, Mail2, or Mail3 -- the server routes the message to its destination over IBM® Lotus® Notes® routing. Notes routing handles both MIME and Notes format messages. If the recipient has a mail file on the third-party server, non-Notesserver.acme.com, their Person document has a forwarding address with the domain "non-Notesserver.acme.com." To route mail over SMTP, Mail1 and Mail3 find a Foreign SMTP Domain document for "*.non-Notesserver.acme.com" that corresponds to an SMTP Connection document listing Mail2 as the server to which to transfer messages. The server sends the message via Notes routing to Mail2, which has the field "SMTP used when sending messages outside of the local Internet domain" enabled on the Router/SMTP-Basics tab of the Configuration Settings document that applies to it. If the message is in Notes format, Mail2 converts it to MIME. Mail2 connects to non-Notesserver.acme.com over TCP/IP and transfers the message over SMTP.

If a user on non-Notesserver.acme.com sends a message to a user on Mail1, Mail2, or Mail3, the server transfers the message over SMTP to Mail2, which has the SMTP listener task enabled on the Basics tab of its Server document, and Mail2 routes the message to its destination over Notes routing.

Configuring these servers requires:

• Enabling the SMTP listener task for Mail2
• Setting up DNS correctly
• Creating a Foreign SMTP Domain document for "*.non-Notesserver.acme.com" and an SMTP Connection document that links to Mail2
