## Improving Accuracy of Spam Detection

You can improve accuracy of spam detection by training the spam filter on the e-mail messages that you have in your mailbox.

To improve accuracy of spam detection:

1. On your Home page, click Spam Filter Tools group.
2. Click Training. All e-mail messages you have in your mailbox are presented on the screen.

   Note: In Parallels Plesk Panel for Linux/Unix platforms, each message is accompanied by an icon in the left column, which tells if a message is recognized as spam - , non-spam - , or not recognized at all - . If you have already trained your spam filter on a message and the results were recorded in the spam filter's database, an icon is shown in the right column.

3. Train the spam filter.

   In most cases, you can tell if a message is spam by looking at its subject line and sender's name. If they do not give you any clue, try looking inside the message using your e-mail program or webmail interface (Home > Webmail).

   - To mark a message as spam, select the corresponding check box and click 'It's Spam!'.
   - To mark a message as not spam, select the corresponding check box and click 'It's Not Spam'.
   - To remove any information on a given message from the spam filter database, select the corresponding check box and click 'Forget It'.
4. Once finished with training, you can remove spam e-mails from your mailbox using your e-mail program or webmail interface.
