How to protect a Plesk server from spam using SpamAssassin?
- Log in to Plesk.
Enable SpamAssassin spam filter in Tools & Settings > Spam Filter.
Note: If Plesk Email Security extension is installed, SpamAssassin is enabled by default.

For further spam filter accuracy improving, it needs to be trained:
Access mailbox using webmail or mail client.
Move all spam messages to the "Spam" folder. This will make the SpamAssassin spam filter recognize spam more efficiently.
