By default it won't filter anything, as I think you now realize. It
doesn't come with a default set of spam criteria, since one person's
spam may be another person's ham. That's why you have to get it to learn
what *you* consider to be spam.

In Fedora: yum install db4-utils
Presumably something similar in Ubuntu.

Bogofilter is not limited to personal computers. Neither is
SpamAssassin. Both are able to work on large servers handling lots of
mail, so a proper database makes sense.
