The only existing information I have is in the Roundup wiki:

http://www.mechanicalcat.net/tech/roundup/wiki/AntiSpam

In slightly more concrete terms, you would have to make three modifications:

1. Pass all incoming email through spambayes to score it. I don't know enough
   about spambayes to really say, but I guess the simplest approach here would
   be to write a custom incoming-mail script that combines a spambayes scorer
   and a Roundup mail gateway. Both would be relatively simple scripts. I've
   included a sketch of that below.

2. Add a "score" attribute onto the msg class attached to issues. This is a
   simple edit of the tracker's schema.py

3. Add a new web action that allows you to train UNSURE mail as HAM or SPAM.
   See the Roundup customisation doc for info about writing new actions, and
   there's also a bunch of examples in the Roundup wiki.

Please don't hesitate to ask further questions here or on the roundup-users 
mailing list.

def process_mail():
    # obtain a message  (as a string) -- maybe re-purpose some code from 
    # roundup.mailgw?
    message = obtain_mail()

    # faked command-line args
    args = []

    # score with spambayes
    # store the score on the message in the tracker
    score = spambayes.score(message)
    if score is in the SPAM range:
       return
    else:
       args.append(('-S', 'score=%s'%score))

    # open tracker
    import roundup.instance
    instance = roundup.instance.open(instance_home)
    db = instance.open('admin')
    handler = mailgw.MailGW(instance, db, args)
    handler.main(message)
    handler.db.close()
