Everyone knows from whom they want to receive email. Anyone else who sends you messages is sending you junk, otherwise known as spam. Espresso does not filter junk.
It only looks for messages you want to receive based on simple, yet powerful rules. Using a number of options available, you decide how to handle messages from unknown senders.
