[SA-exim] sa-exim with SQL user prefs

[Fábio Berbert de Paula]

Hi all,

I compiled sa-exim in replacement of local_scan.c on 
Exim4-4.20 source and configured the same do perform a 
SQL search for userpref, according the documentation 
about SQL on spamassassin oficial web site.

As well, all of this 'works', but in a lot of times 
a local user get his address in a WHITELIST_TO test
without explanation and accept a SPAM. How can I 
debug the why is it hiting on this test?

Note: sa-exim is using only the @GLOBAL user prefs, 
if is there any way to do sa-exim load a single user
prefs, please tell me. It can be done via ACL right?
Any URL to give me? 

My ISP receive a bit more than 400.000 messages/day, 
with spamassassin + exim3 + director, we're blocking
50.000 messages/day, with sa-exim + exim4 only 20.000
because the problem with the misterious WHITELIST_TO.

Other note: I'm using the same version and configuration
of spamassassin in both cases: exim3 and exim4.

Please, give some idea or sites do look for documentation.

Thanks,
