Using spamassassin trying to get bayes to work. I don't want to install MailScanner.

Does anyone have it working?

I put:
use_bayes 1
auto_learn 1

in the bottom of one of my sites user_prefs file (home/site/.spamassassin/user_prefs). I can see in the mail header it is autolearning spam (autolearn=spam).

However:

root@secure [/home/anysite/.spamassassin]# sa-learn --dump magic
ERROR: Bayes dump returned an error, please re-run with -D for more information

What is the deal here? bayes_seen and bayes_toks ARE being updated.

Thanks for any tips.
