Spamassassin is not perfect. No machine will be as intelligent as a
person..the "brains" just don't work the same.

If they want NO false positives or negatives, they will need a warm body
sitting at a desk reviewing what gets caught and correcting what doesn't get
caught.
If they can find a lawyer who;
1) never makes a mistake
2) admits it when he could be wrong
maybe they will find a machine that good.
Many law firms only screen for viruses, and let all spam in just so they don't
miss things.

The reason people have multiple outbound gateways is for;
1) load
2) redundancy

What I would like to see is an addin for mailscanner that watches outgoing
mail and whitelists the "to" addresses for a configurable period of time.
Usually mail sent out is expected to be replied to.
But IANAP.
