Does anyone know a good free spam filter, which I can use with Outlook Express?? I'm using Outlook Express at home, because I don't get a lot of mails home, but lately I'm getting at least 50 spam mails every day, which is annoying.

My ISP has some filters I can set, but it doesn't work well, and every mail gets blocked instead.

Or can anyone give me a hint which free mail program I could use instead of Outlook Express?
