Setting up SMTP routing to external Internet domains

To send messages over SMTP to destinations outside of the local Internet domain -- for example, to the Internet or another private network -- you must enable external SMTP routing.

Before you begin

Make sure that you prepared your system to send mail to the Internet and that you already have a Configuration Settings document for the server(s) to be configured.


  1. From the Domino® Administrator, click the Configuration tab and then expand the Messaging section.
  2. Choose Configurations.
  3. Select the Configuration Settings document and then click Edit Configuration.
  4. On the Router/SMTPBasics tab, for the field SMTP used when sending messages outside the local Internet domain, choose one of these options, and then save the document:
    • Enabled - to use SMTP to route mail to the Internet
    • Disabled - (default) to prevent the server from routing mail outside the local Internet domain


The change takes effect after the next Router configuration update. To put the new setting into effect immediately, reload the routing configuration.
