Once the service is contracted with ProfesionalHosting, our colleagues will install the module on your server and notify you when it is installed.
Once installed, its use is very simple.
1. Enter Plesk, click on Extensions on the left, then click "Professional SpamFilter"
2. Once inside the module, click by selecting the domains you want to protect, and then click the "protect" button. It will activate the filter on the domains you want to protect.
3. If you have made a mistake or want to remove it from any domain, select it and then click the "unprotect" button.
