Spam Filter icon in the Tools group. - Click the Training tab.
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. - Train the spam filter.
