All hosts found in blacklist

I’ve enabled logging with the following blacklists:

sbl.spamhaus.com

xbl.spamhaus.com

bl.spamcop.com

dnsbl.sorbs.net

What I’ve noticed keeps ocurring (even when I use just 1 blacklist such as spamhaus) is that EVERY host that connects is found in the blacklist.

I’m wondering, is this a DNS issue perhaps, or could it be something in domino that is amiss?

Thanks alot.

Is it this?

Don’t use spamcop.com

Spamcop.com is not spamcop.net (which you should be using) and it has a wildcard A record (which means that ANY dnsbl lookup on any zone under spamcop.com will always return a hit).
