Battling to bet DNSBL to work!

[WipeOut <wi...@users.sourceforge.net>]

Hi,

I am battling to get DNSBL's working with my SA setup..

By default spamd was starting with the following args..
--max-children=40 --local --nouser-config --sql-config 
--username=vpopmail --socketpath=/var/hsphere/mail/spamd 
--syslog-socket=none
and..
skip_rbl_checks 1
in the local.cf

So I changed these to the following..
--max-children=20 --nouser-config --sql-config --username=vpopmail 
--socketpath=/var/hsphere/mail/spamd --syslog-socket=none
and..
skip_rbl_checks 0

Since doing this the accuracy has dropped from about 65% to about 50%..
Looking at the spam reports included in tagged spam messages I don't see 
that any of the DNSBL's being used..
I have tested Net::DNS and it is resolving..
I have read most of the docs and searched google without any luck..

Using SA ver 3.0.2..

Any help would be appreciated cos the spam is driving me insane..

Thanks..
