Ooops - I've just looked at my question again and realise that the question looks ridiculous ;) What I _meant_ to write, was that I get some message that are classified as 'unsure' when the declared spam probability is 0.8 or higher. i.e. the spam rating is higher than the spam threshold.

And I apologise for asking a repeat question :( I've been following the list for a while but somehow didn't read that thread - sorry.
I've lodged a bug report.
