You can use the Diagnostics Console to troubleshoot Distribution Service issues. Diagnostics information is logged under the Distribution Service tab in the Diagnostic Console.
For general information on diagnostics, see the Diagnostics Service reference guide or the Diagnostics Console help files.
When an Email Sending task is manually initiated from the Unity Management Console, the logging levels set in the Application Server's web.config file are respected. When an Email Sending task is automatically triggered by the Unity Scheduler, the logging levels set in the Unity Scheduler's app.config file are respected.
In either the Application Server's web.config file or the Unity Scheduler's app.config file, modify the logging level to activate logging. If logging is activated, it always occurs at the Verbose level. Setting the minimum-level key to different values will yield the results described below:
-
If the line specifying the minimum-level is commented out, information about the Distribution Service is logged at the Verbose level.
-
Trace- Information about the Distribution Service is logged at the Verbose level.
-
Verbose- Logs important information and events regarding the Distribution Service.
-
Warning- No Distribution Service information is logged.
-
Error- No Distribution Service information is logged.
-
None- No Distribution Service information is logged.
If the Distribution Service sends an email without a specified To address, an SMTP server error displays on the Errors tab. The SMTP server sends Undeliverable Message notifications to the From address specified in the message template.
