Log Reference

Classifier

Classifier

The classifier field is in every FortiMail log message where type=statistics.

The field indicates which FortiMail features scanned the email and resulted in actions that were recorded in the disposition field.

If you view the log messages on the FortiMail GUI or send the logs to a FortiAnalyzer, then dispositions and classifiers are displayed as a description such as Fragmented Email. Raw log files, however, display them as hexadecimal numbers.

The following tables correlate the hexadecimal numbers with their description in English.
