[Caveat: I cannot test what I describe below since I do not use this
 setup any more.]

First, make sure that SpamAssassin is installed on your system. For
instance, open a terminal and type 'spamc -V', and it should tell you
the installed version.

Then, in your .gnus.el, add something like this:

  (setq nnmail-split-methods 'nnmail-split-fancy
        nnmail-split-fancy '(| (: kevin-spamassassin)
                               "catchall.inbox"))

In which "catchall.inbox" is the group to which all non-spam mails go.

Also add the function kevin-spamassassin, as given in the manual (and
above). The "spam" in the last line of the function is the group to
which spam emails go.

Good luck.

[And you may rename 'kevin-spamassassin' as you wish, as long as you
also use that name with 'nnmail-split-fancy'.]
