The email spam filter SpamAssassin in a Box seamlessly integrates into the email download process. It creates no lags and the spam blocker does not need to be activated manually: all emails are scanned for spam automatically.
- The email server receives the emails and forwards them to the SpamAssassin.
- SpamAssassin analyses the emails and calculates each email's spam score.
- SpamAssassin then adds the spam score information to the email header and sends the email back to the server
- The server processes the email according to the additional information. You can, for example, move all emails with a spam score exceeding certain limits to the spam folder and let all clean emails pass through to your inbox.
