Why would you need to do that? With solutions like DSPAM, that's up to
users to decide. They teach the filter what *is* and *is not* spam *to
them*, and the computer does the rest of the work. An admin is involved only
so much as it takes to install and configure the resource. There should be
minimal or no babysitting and hand holding involved.

No, I believe you. I know how it works; I've used it. You're saying it
filters "90% or more", but a Bayesian filtering solution is ~97% accurate at
the very start, and with a decent sample, it gets to be ~99.99975% accurate,
which seems to be below your required 0.1%. And because it is the user who
decides what is spam, no e-mails are lost by the ISP. But don't let me talk
you into it though; you have Google.
