Filters Don't Work
The filter model is fundamentally flawed because filters have no way of distinguishing between "bad" and "good" emails. All of the major enterprise or corporate solutions on the market today attempt to guess, using patterns and keywords, what is (and what is not) spam. Sender Address Verification (SAV) is the best answer to the unwanted email problem. SAV is based on the premise that all senders must announce and authenticate themselves the first time they send a piece of e-mail.

Enterprise Business - I.C.E. Box
The Sendio I.C.E. Box is an enterprise-class appliance capable of processing millions of messages a day per server. It is a hardware device that prevents spam from reaching corporate email servers: in other words, there is no spam to filter because unwanted messages never even make it into the system. When a message is received from a first-time sender, the box immediately identifies the message for special treatment, and senders receive an immediate acknowledgement of their messages and a request to verify their email addresses.
