heh heh.  I think it was simpler when I started and has kind of
balooned.  However, my setup still works....

Step 1:  this goes in your .gnus.el:
(setq
  nnimap-split-rule 'nnimap-split-fancy
  nnimap-split-inbox "INBOX"
  nnimap-split-fancy '(|
		       (: spam-split)
               ;; For example (any ".*bbdb.*" "mail/ZIn.bbdb")
		      ;; default mailbox
		      "mail/Inbox.good")
)


Step 2: - I do this with customize, but I suspect you can do it with
setq-s.  

 '(spam-bogofilter-path "/usr/local/bin/bogofilter")
 '(spam-junk-mailgroups (quote ("mail/junk")))
 '(spam-process-ham-in-spam-groups t)
 '(spam-split-group "mail/junk")
 '(spam-use-bogofilter t)
 '(spam-use-bogofilter-headers nil)

Step 3: Set parameters in mail/junk 
I think you need to go to group-customize to do this (G c on the
group).  I find this personally annoying and adds a layer of mystery
to the whole thing.  I think there is a way around it, but I'm not
sure what it is.

a) Check Group contents spam/ham classification to make it "spam"
b) Set the Spam summary exit processor to "Ham: Bogofilter" - this
will allow you to mark Ham in the spam group for training when you
get a false positive.
c) Choose a "Destination for ham articles"  I just put them in my
mail/Inbox.good.
d) Set Ham mark choices - I use gnus-read-mark and gnus-ticked-mark.
e) I set Expire wait to 2 days.  

You could also set this group to train on the spam, but bogofilter
already knew it was spam, so that may be overtraining.  

This comes out in my groups parameters looking like:

((uidvalidity . "1074123432")
 (spam-contents gnus-group-spam-classification-spam)
 (spam-process
  ((ham spam-use-bogofilter)))
 (ham-process-destination "nnimap+opg1.ucsd.edu:mail/Inbox.good")
 (ham-marks
  (gnus-read-mark gnus-ticked-mark))
 (expiry-wait . 2.0))

Let me know if this doesn't make sense.

Note that I do this over IMAP, but bogofilter runs locally.  It
should, however, work with any backend.

Cheers,  Jody.
