I've been a part
of this list for some time now, in mostly lurking fashion. My question to the
group is, if you read all the anti-spam vendors (me included), they all claim
high-9 catch rates and near-zero false positives. If this is the case, why are
we still here trying to eliminate spam when one would think that, if the
claims are true, the spam problem has been solved? I can only think of
one of three reasons:
1. The vendor
claims are false. In the real world, you still get lots of undesireable
email.
2. The vendor
claims are true, but we're a bunch of perfectionists searching for infinite
resolution of Pi.
3. The filtering
paradigm is a non-solution due to increased use of recipient resources
(bandwith, storage, processing, end-user time,
etc)
