psy writes "physorg has a story on a new spam firewall developed at The University of Queensland. The new technology is the only true spam firewall in existence, according to co-developer Matthew Sullivan. "Existing anti-spam software filters out spam whereas ours puts up a firewall, stopping all email traffic and only allowing real mail through," said Mr Sullivan. "In addition, our technology is accurate and fast. We recently completed a successful trial of a key layer of the spam firewall and it processed the emails at 90 messages per second, misclassifying only one out of 25,000 emails." "It turned out that the software was even better than us, picking up spam we'd incorrectly classified as legitimate emails."
