File Rules

File Rules allow you to create rules containing either block or allow actions for file extensions, file types or file expressions. File rules are assigned to Spam/Virus/File Policies which in turn are assigned to Internal Recipients.

Hermes SEG file rules are processed from the top down fashion. In other words, as a file rule gets processed, block/allow actions on the to of the rule get processed first. If a match is found then the action is taken and all further processing of the rule stops.

Default System File Rule

Hermes SEG already comes pre-configured with a Default System File Rule which is assigned to all the system Spam/Virus/File Policies. The Default System File Rule cannot be edited, it can only be viewed or copied in order to be used as a starting point in creating custom file rules (Figure 1).
