spam filtering with postfix and virtual domains

I have been fighting on an off with amavisd-new for my mail
setup at work. I use 
postfix and virtual domains. I've got amavisd-new setup as
described in the 
Gentoo Mail Filtering Gateway Guide (or something like
that), except for the 
mysql config for amavisd.

At some point, my amavisd setup decided to stop checking
mail for spam. I don't 
get spam headers or anything in the logs indicating it's
checking for spam. It 
still checks for viruses using clamav, however. Also,
amavisd's configurability 
for SA is piss poor, at best.

I can use spamassassin and spamc/spamd just fine, so I know
SA works. 
Unfortunately, it doesn't seem as if amavisd has the ability
to use spamc 
instead of the SA modules directly.

I'm used to a nice "simple" setup with procmail,
clamassassin, and spamc/spamd. 
I've got this setup at home, and I love it. The
configuration and maintenance is 
very easy. Unfortunately, postfix's virtual delivery agent
is not capable of 
using even a global procmail setup to do some basic
filtering.

I'm looking for 1 of 2 things: a way to have amavisd run
spamc instead of using 
the SA modules itself, or a local smtp daemon (like amavis)
that just simply 
runs everything it gets through procmail, spamc, or whatever
you choose with a 
"simple" setup. Does anyone have any suggestions?

Check to make sure spam checking is not turned off.  At some
point
the stock gentoo amavisd config file had spam checking off
by default.
Also keep in mind there is more than one place (variable
setting) where
it can get turned off.

Get amavisd to work? . 
Seriously, I have no useful suggestions as I
myself only have experience with amavisd-new.  And it does
work and check
spam for me.  And you can configure spamassasin stuff that
it doesn't
have vars for through the standard spamassassin config
files.  (I haven't
tried the mysql setup for amavis yet; that's next on my
list...)

Any suggestions for what values to check? I looked at
everything in the 
SpamAssassin section of amavisd.conf, but nothing stood out
at me.

I wasn't getting the spam headers until I set

$sa_tag_level_deflt  = -100

Now I see the headers, though nothing ever seems to score a
high enough 
spam score to get marked as spam... And I imported my spam
db from my 
old server and have been training it on spam every night and
on ham 
whenever I can. Don't know if the spammers are just getting
better or if 
I didn't set something right.

The one that got me was, I think:

     bypass_spam_checks_maps

There are several places it appears in the stock config;
make
sure they are all commented out or set to some useful value.
