Thank you Matt =).  So most of the heuristics seem to be looking for SPAM.
What are the ones that would push a mail towards being HAM (and that are not
ignored by autolearn bayes)?  So far I have found one: ALL_TRUSTED.
A few network tests also qualify:
        RCVD_IN_BSP_OTHER
        RCVD_IN_BSP_TRUSTED
        HABEAS_USER
Other than that, SA is just relying on not hitting many spam rules. The 
default autolearn threshold is slightly positive for this reason...

I myself use a slightly negative autolearn threshold, and I have a bunch of 
custom rules with small (no less than -0.2) negative scores that help place 
mail into my ham autolearning.. Even so, ham autolearning is quite a bit 
less frequent than spam autolearning...

# grep "autolearn=spam" /var/log/maillog |wc -l
   9030
# grep "autolearn=not spam" /var/log/maillog |wc -l
    478
(note: I use MailScanner which uses this log format... IRC, normal SA logs 
as "ham" instead of "not spam")
