it's not 90% Cisco is wrong about that, it's more like 98%. We block more than 90% at the perimeter, another 50% of the stuff that gets through is junk, and another few % of that is marked as junk by the end user.
Need more death sentences for spammers, scammers, 419ers and the like.
I propose a pay-per-view event named "Spammer Island" where we can hunt them, use webcam controlled firearms and the paying public can watch us chase them down, bayonette them in a winner takes all sort of no holds barred blood fest where the blood comes from the spammers and all we win is cleaner mailboxes.
