Description
This means that an application on the system has reported to ASL that a user has failed to authenticate to the Exim mail server.
You should investigate this event as it may be part of a broader attack.
Troubleshooting
False Positives
No false positives are known to exist for this. The event is not caused by ASL, but rather the application reports to ASL that it has experienced an authentication failure for a user. If your application is incorrectly reporting this, please report the issue to the application vendor. If ASL is incorrectly reporting an event, that is the application is not authentication failures, please let us know.
