Content filter policies can be set at the server level, domain level, and mailbox level. Policies are hierarchical meaning that each policy inherits values from it's parent unless it is overwritten at the child level (Server level -> Domain level -> Mailbox level) .
Server Wide Policy
To manage the server level policy go to Warden -> Settings -> Content Filter Settings -> Policy Settings.
Domain Policy
To manage a domain level policy go to Warden -> Policies -> Click the edit icon next to the domain name policy that you want to change.
Customers can also manage their Warden domain policy directly though Plesk under Domains -> Click on their domain -> Mail -> Warden Anti-spam and Virus Protection. Admins can disable customer access under Warden -> Settings -> Panel Application -> Permissions.
Mailbox Policy
To manage a mailbox policy go to Warden -> Policies -> Click the domain name -> Click the edit icon next to the mailbox policy that you want to change.
Customers can also manage their Warden mailbox policies directly though Plesk under Domains -> Click on their domain -> Mail -> Mail Accounts -> Click the Settings entry under the Warden Column. Admins can disable customer access under Warden -> Settings -> Panel Application -> Permissions.
