Trash rules let you define when to ignore or include inbound items from specific email addresses or domains.
Trash rules are used during search. By default, a trash rule causes items coming in from specified email addresses or domains to be omitted from search results.
You can define trash rules to be used at the application level, but they can be propagated to sub-departments. Application-specific trash rules can be deactivated at the application level. A deactivated department trash rule does not modify the original application trash rule. Trash rules cannot be deleted or modified; they can only be deactivated.
Note: You must have the application-levelManage Trash Rulespermission to add application-specific trash rules. By default, users that have theRule Adminrole have this permission.
