Stop Spam Email

i have over 2997 spam junk mail poated on my email address, how do i stop this for good

i get spam mail everyday in my hushmail account, but there are no options on stopping them. hell i could use my yahoo account and they have a spam folder and its free.

I keep getting about 2000 mails from this stupid home business exchange, it comes automatically, ive tried the filter, blocking etc. NOTHING works.
