integrating spamassassin into pop retrieval?

integrating spamassassin into pop retrieval?

[Bill White]

How can I integrate spamassassin into this retrieval & splitting
system?

- email mysteriously arrives at pop.wolfram.com

- gnus grabs it via pop3.el and writes it to mail-source-crash-box,
  and stores a copy thanks to (setq mail-source-delete-incoming nil).

- the file is split via 

  (setq nnmail-split-fancy
        '(|
          (from ".*Dan Largent.*" "personal")
          (from ".*Michelle Largent.*" "personal")
          ("Subject" ".*Voice mail waiting for x.*" "voice-mail")
          ("Return-Path" ".*<dmeadows@idirect\\.com>.*" "Explorator")
  [...]
  ))

and is written into nnml files in the indicated dirs.

Is there a way to run spamassassin on each email as it's split?  Maybe
a function at the top of nnmail-split-fancy which would call it?  I
think I want to keep spamassassin completely local and use it only
when I explicitly retrieve email via 'g' in the Group buffer.

Thanks!
