It’s not a new story, but today I had to do it again to restore our email relay successfully. so I am writing this just as a reference.

Recently we were having some issues in sending emails to various domains , in some particular case, our Public IP was blacklisted at one or two spam lists. To sort it out, we used our ISP’s SMTP (example: relay mails successfully. Here is how you can add/change the relay host.

  • From the Domino Administrator, click the Configuration tab and then expand the Messaging section.
  • Choose Configurations.
  • Select the Configuration Settings document and then click Edit Configuration.
  • Click the Router/SMTP Basics tab.
  • Complete this field, and then click Save & Close:

Relay host for messages leaving the local Internet domain

As showed in the image below . . .


To take changes take effect immediately, issue this command at domino admin client

tell router update config

To remove relay host, simply remove the smtp entry and reload config.
