I'm not surprised you're having issues

Spamcop, for example, is fine for scoring, but blocking based on it will 
hurt you.

XBL includes CBL, so there's little point in doubling up on the entries.

spamhaus.org and spamhaus-XBL do not look like correct entries and are 
probably throwing errors in your logs (you have checked them I hope!)

You should _always_ read the listing criteria for any DNSBL _before_ you 
start using it. If you are unsure do not use it.

Have a read of:

It's a bit old, but a lot of what I say in it is still true.
