Chapter 7Spam filterKerio MailServer contains the SpamAssassin antispam filter. SpamAssassin is based oncontent analysis (spam messages usually contain specific attributes that can be searchedfor and evaluated by the filter). Each message is assigned a numeric score; if this valueexceeds the limit set in Kerio MailServer, the message is marked as spam.The spam filter may let some spam messages through from time to time by mistake(their score is low) and mark some regular messages as spam (their score is too high).For the reasons above, the antispam filter allows modification to the database used forrecognition of spam messages. This method, however, requires user input. Users haveto reassign the incorrectly evaluated messages to correct types (spam / non-spam) sothat the filter learns to recognize them in the future.Kerio Outlook Connector uses the Spam and Not spam buttons located in the toolbar tomark the messages correctly. Highlight the incorrectly marked message and click oneof the buttons. The filter receives information regarding update of the database. Thisdecreases chance for incorrect deliveries.You can add the Spam and Not spam buttons to the toolbar in Tools → Customize menuor remove them. The Toolbars tab includes the Kerio Outlook Connector option. Simplyselect or unselect it by clicking to enable/disable the bar with the buttons.The Spam button displays a warning message by default. To treat the message as spamand discard it, a confirmation is required. Use the Tools → Options menu on the Spamtab (see figure 7.1) to enable/disable displaying of the warning message.Warning: If the Spam/Not Spam buttons are not available after installation or startup ofMS Outlook, it is necessary to remove Kerio Outlook Connector from all forbidden itemsof MS Outlook (see chapter 12.1).7.1 The Spam tabThe Spam tab provides several tools to fight spam:Confirm marking mail message as spamThis option enables/disables alert window displayed upon clicking on the Spambutton which is available in the toolbar.33
