Errors found in the SMTP filter policy

analyzer which warns the administrator when a rule inhibits another rule or if an error has been
created on one of the rules.
This analyzer shows rule creation errors and coherence errors.

Status of the rule:
Enabled, the rule is used for filtering.
Disabled, the rule is not used for filtering. If this rule is disabled, the line will be
grayed out in order to reflect this.
REMARK

the request, it will perform the specified action and stop there. This means that
if the action specified in the rule corresponds to Block, all rules below it will
also be set to Block.
