I used both, and they are working. the problem is that lots of spam is not correctly rate by spam assasing (even though i am using 4.0 as spam rate for SpammAssaing config) and the lists I had added in map_rbl_domain dont block them. they are :

Do you have postfix 1.1? The syntax above suggests you do. Postfix
2.x supports a more flexible rbl syntax. See:
http://www.postfix.org/uce.html

The wirehub dnsbl's have been inactive for quite some time, so that
doesn't do you any good.
I'm not familiar with the arix.com lists.

Some widely used lists that you aren't using are sbl.spamhaus.org and
cbl.abuseat.org; you might check their web sites to see if their listing
policies are compatible with your goals.

You can find a pretty complete list of active dnsbl's at:

On the spamassassin side, there are custom rules you can add to
improve scoring. Some popular rulesets can be found at:
