The Bayesian anti-spam filter : Configuring the Bayesian filter
1. In the GFI MailEssentials configuration, select the Anti-Spam > Bayesian Analysis node, right-click and select Properties. This brings up the Bayesian Analysis Properties dialog. From the General tab, select the Enable Bayesian Analysis checkbox.
2. Ensure that the Automatically learn from outbound emails option is checked. This option will continuously update the legitimate email database with outbound emails.
3. From the Updates tab, you can specify how frequently GFI MailEssentials should check for updates to the spam database. To do this, select the Automatically check for updates checkbox and specify an interval in hours in the Download/check every field. If you want to trigger an instant download, click the Download updates now button. The updates will be downloaded from the preferred server selected.
