I didn't say that I actually see them, I said I get 1000 that can't be
rejected/discarded as spam with 6-sigma accuracy.  Dealing with the
1-in-100 Type II errors and the 2-in-100 Type I errors in the 1000 is
what much of the "automatic processing" is for.

Suggestions are welcome.  Most of the problematic mail is in Japanese
or Chinese however, and I don't know any tools (including GMail which
throws up false positives in my spam folder about once a week) that
get 2- or 3-sigma performance on those languages, at least not in my
multilingual context.  So I quarantine, and do a lot of tweaking of
packaged tools and postprocessing myself.

At least some commercial tools for Japanese are really horrible --
about once a week I get mail from a colleague that is marked as "spam"
or "suspected spam" by my *employer*'s filters, and traffic on this
list gets marked that way about as often. :-(
