This is what I usually do when I set up a new user on bogofilter.  It
makes the most sense to them, I think.  Everything comes in as unsure
until they train them one way or the other.

This isn't a terrible idea.  For some users who don't really want to
train much, I'll set them up with a default wordlist (usually my own),
which right off the bat usually gives them 99% accuracy.  The minor
differences between their ham/spam and mine they simply have to train
on.  Kmail could start off with a very, very simple wordlist containing
very common hammy words (such as "kmail", "the", etc).  E.g., they could
train their welcome message as a ham.  That would at least get the
process started and would not really "pollute" the database, as those
tokens would probably become neutral soon anyway.

If this is possible, I'd recommend this approach too.
