Amavisd.conf is one of those files you have to read like a lawyer....  ;-)

Look for something in Section IV (notifications) that reads like this:
$final_spam_destiny = D_DISCARD;

(You could have that set to D_BOUNCE, which would bounce spam at
your kill level, but you should NEVER bounce spam IMHO)

If it does say D_DISCARD that means  spam that met your Kill_level is 
summarily dispatched to /dev/null

These will usually be tagged in /var/log/mail with a line like this

EVEN IF your Final_Spam_Destiny was Bounce, it gets converted
to discard if the spma score gets up to your Cutoff_level.

With the setup above, you are only going to see spam that scores
between 5 and 10.  Spam that scores higher should be discarded, or bounced
or quarantined (depending on your Final Destination setting.  Stuff
that scores less than 5 is not considered spam.

So the key here is to set your kill_level suitably high such that 
you won't have false positives getting lost.

Recommendation:  Get your bayes working first.  Install razor2
and configure it so that spamassassin can check the mail against
razor2.  

THEN:  In my ever so humble opinion, (smirk), the above levels are 
just fine.  In several years or running spamassassin, I've never had
a false positive score above 10. And I check for this EVERY new version of SA.
( I set my kill level to 15 for a week just to make sure).

Your situation may be different, but I just don't want to see anything that
scores above 10.
