Also check to make sure your not using HUGE rulesets like the 2
blacklist ones, that's what caused a problem here, once we stopped
using those 2 all was happy.

How many children are you running?  Overload is almost always due to running
out of memory and going into thrashing.  This happens because the total size
of the spamd children is larger than your available memory.  The total size
can be because you have too many children running, or sometimes because the
children get too big.

I would expect the children to be around 50MB or a little less, depending on
the rulesets you have.  You can check this.  If one or more of the children
is much bigger than 50MB, then this may be causing your problem.

You should also check how many spamd children are running, and compare their
total size to your available memory size.  With 512MB of memory, you
probably do not want more than about 5 children maximum.

All of this assumes you are running spamd.  If you are using some other
method, then the problem might lie elsewhere.

My problem still remains: I disabled ALL the rules I use to check (Rules 
du Jour, Bayes, Razor and Pyzor) and, believe it or not, it is still 
getting overloaded :(

There is some way to check WHAT is causing the overload? Some debug?! 
(can I check the possible cause os the overload with "spamassassing 
--lint -D" command?!)

Thanks to all :)
