Help No Logs

I thought maybe I was fortunate enough when I first installed it to not have any spam issues. I forgot about checking the logs after I initially did until recently. We've been hit with waves of spam recently and I still see NOTHING in my logs.



It has been this way from the start, which makes me question if this is even working since so much spam has been getting through lately. How can one check to see if this is actually working? And how come there are no logs (and never has been)?
