Log messages often contain clues that can aid you in determining the cause of a problem.
FortiMail units can record log messages when errors occur that cause failures, upon
significant changes, and upon processing events.
Depending on the type, log messages may appear in either the history, event, antivirus, or
antispam logs. For example, to determine when and why an email was quarantined, you
might examine the Classifier and Disposition fields in the history log; to determine if a
FortiGuard-AntiSpam scan query was able to reach the FDN, you might examine the
Message field in the antispam log.
During troubleshooting, you may find it useful to reduce the logging severity threshold for
more verbose logs, to include more information on less severe events.
