One thing I've just noticed using the Outlook client (although I think
it's a feature of the algorithm, rather than specific to the client).
A couple of hams ended up in my "Unsure" folder. No problem, I trained
on them as ham. But they hit my inbox with a spam score *still* in the
25-35 region. So if I refilter, they pop up in my unsure folder again.
Nothing I can do will make the messages score as ham.
Refiling based on spam scores is a rare operation (I only noticed
this because I forgot to tick the "only unscored messages" checkbox
in the filter dialog), but the behaviour is annoying, as well as being
unnerving. I don't think there's anything which can be done at the
algorithm level (the algorithm is effectively saying "OK, I know
you're saying it's ham, but it still looks pretty odd to me...") but
at the client/user interface level, maybe there should be an extra
property "Trained", which says that this message has been specifically
confirmed as ham or spam, so that it won't get filtered. I'm not sure
how, or if, this would translate to other types of client.
