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 in the Tools group.
2. Click Training in the Tools group.

   All e-mail messages you have in your mailbox are presented on the screen. 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.
5. To remove messages from the list, select the messages you want to remove, then click Remove Selected.

If you have accidentally made your spam filter learn a great number of spam e-mails as non-spam or vice versa, your spam filter will likely produce incorrect results. In this case, clear the spam filter's database and then repeat training.
