(technically not software but couldn't think of a better place)
I've recently decided to take back my inbox. I was getting a lot of email and realized I was just deleting 99% of it

So far I have unsubscribed to a ton of lists that I must have accumulated over the years and that has put a major dent in the inbox flood, but there are quite a few that i didn't sign up for, are obvious spam/viri/phish and provide no way to get unlisted.
So, I have signed up for SpamCop and have been forwarding all of it there.
Has anyone used something like this in the past/present?
