Implement DNS Whitelists
Plesk does not currently support DNS Whitelists like it does RBLs, such as the list at dnswl.org. There needs to be a way to add this from the Plesk UI.
The Postfix main.cf config directive is permitdnswlclient.
Whenever a Plesk upgrade happens, the setting, if added is removed and needs to be added back manually.
Thank you for your input! We will consider this functionality in upcoming releases, if it will be popular.
