Changing the logging level for mail

By default, when the Router is unable to deliver a mail message, Domino® records information in the server log file (LOG.NSF). When you troubleshoot messaging, you may want to record additional information in the log file.


  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 > Advanced > Controls tab.
  6. Complete this field in the Miscellaneous Controls section, and then click Save & Close:
    Table 1. Logging level



    Logging level

    Choose one:

    • Minimal - Domino® logs all mandatory status messages and fatal error messages.
    • Normal (default) - Domino® logs all minimal events, plus warning messages indicating conditions that do not cause processing to stop.
    • Informational - Domino® logs all minimal and normal events, plus informational messages involving intermediate storage, MAIL.BOX access, message handling, message conversion, and transport status.
    • Verbose - Domino® logs all minimal, normal, and informational events, plus additional messages that may help you troubleshoot system problems.
    Note: To prevent the log file from becoming excessively large, use Verbose logging only when troubleshooting specific problems.
  7. The change takes affect after the next Router configuration update. To put the new setting into effect immediately, reload the routing configuration.
