 Also: http://ixhash.sourceforge.net/
 Using all three lists works great here.

it olso calc the md5 sum pr lists :/

so internal it can imho be speeded up by a rewrite :)

flow:
md5 sum rule test #1
test sum on all lists you define

md5 sum rule test #2
test sum on all list you define

md5 sum rule test #3
test sum on all list you define

speed improvements, one thing is now left, what about the scores pr test ?

i have disabled the ixhash, and enabled the myixhash with mysql backend, works
better :-)

 greetings.
 most of the spam we get (like 90%)  is the usual internet noise. sa filters
 them perfectly with 10 to 20 points.
 Unfortunatly from time to time there are waves of very prefessional spam.
 I wonder how you react on those.  Do you quickly hack up an sa rule to filter
 by specific words?  Do you have a central repo for rules?
 -- 

I don't know if anyone has mentioned it yet, but you might want to make sure
you have razor and DCC running.  Both are good at catching new spams as they
begin to move around the world.  In fact, can react a lot faster than you
can in setting up custom keywords.

One more thing, the commercial DCC reputation scores give a percentage of
'bulk' for every ip that connects to your system (you need the commercial
DCC server and Mark Martinec's patches to DCC.pm so SA can see the scores).

I meant a rule against http://(?:www\.)geocities\b or the like, not against 
the specific site on geocities.  That should be good for about 2 points and 
help a lot with a real common spam target.  It certainly won't get all of 
your spam, but it will get an amazing amount.
