Hotmail is the most aggressive against spam, Yahoo is getting there. I check my Spam folder all the time, then I click Not Spam if anything is there I do not want being sent there. Hotmail and Yahoo will also block Spam, but the user I believe has to allow that on an individual basis. My companies email is added to spam filters all the time, we are in a constant battle as we do not send Spam, everything is sent to individuals that are opted in with us. We are a large retail based company, offering multiple services, we send a lot of email.
