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.

I have tested this with Plesk Obsidian. Actually, when you place a "permit_dnswl_client" command into the /etc/postfix/main.cf file similar to this:
smtpd_client_restrictions = permit_mynetworks, permit_sasl_authenticated, permit_dnswl_client list.dnswl.org, reject_rbl_client sbl.spamhaus.org, reject_rbl_client xbl.someblacklist.org, reject_rbl_client someotherblacklist.org
you can still update the mail server configuration through Plesk GUI and the configuration remains in place. This is true even when you edit the "DNS zones for DNSBL service" field in Plesk. So as a workaround for the time being I suggest to edit /etc/postfix/main.cf once manually.
