Log message dispositions and classifiers

Each history log contains one field called Classifier and another called Disposition.

The Classifier field displays which FortiMail scanner applies to the email message. For example, “Banned Word” means the email message was detected by the FortiMail banned word scanner. The Disposition field specifies the action taken by the FortiMail unit.

If you view the log messages on the FortiMail web UI or send the logs to a Syslog server, the dispositions and classifiers are displayed in English terms. However, if you download log files from the FortiMail web UI to your PC and open them, the dispositions and classifiers are displayed in hex numbers.

The following tables map the numbers with English terms.

Note

When the classifier is “Attachment Filter”, a new field “atype” (attachment type) is also displayed. This field is for debug purpose only.
