One of the new features in the brand new release 8 of IBM’s Lotus Notes an Domino is the SMTP outbound authentication (SMTP AUTH) to relay hosts. Most of the ISPs only allow authenticated users / server to relay mail thru their server.
To setup this new feature follow these simple steps:

• 1. Make sure you already have a Configuration Settings document for the server(s) to be configured.
• 2. From the Domino Administrator, click the Configuration tab and expand the Messaging section.
• 3. Click Configurations.
• 4. Select the Configuration Settings document for the mail server or servers you want to administer, and click Edit Configuration.
• 5. Click the Router/SMTP – Basics tab.
• 6. In the field “Use authentication when sending messages to the relay host,” choose one of these:
  • Required – Checks whether the server can authenticate. If the server cannot authenticate, no attempt is made to try a non-authenticated session.
  • Enabled – Checks whether the server can authenticate. If the server cannot authenticate, an attempt is made to try a non-authenticated session.
  • Disabled – The SMTP Authentication feature is disabled. Authentication is not attempted.
• 7. Specify the SMTP account name in the Name field, and the SMTP password in the Password field.
• 8. Type the host name into the field “Relay host for messages leaving the local internet domain”.
• 9.Click Save and Close.

I’ve only tested with freenet.de. maybe there are problems with other ISPs as in the past with 1&1.



I would like to say thank you to Ramon Bisswanger who invented and developed the SMTP AUTH tool. I’ve used his great tool to send mail via my Domino server without any problems for the past 3 years.
