CentOS - Jul 2011 - Spamhaus with Zimbra Mail on CentOS

I realize this is slightly off topic, but I've noticed recently that
I've been unable to preform RBL lookups using the the zen and sbl spamhaus
RBL lists. Currently using Zimbra Collaboration Suite using CentOS 5 I'm
seeing logs showing the following output.

[root at phantom ~]# cat /var/log/zimbra.log | grep spamhaus

After doing some reading I've tried a number of DNS servers ( thinking the
issue may have been DNS poisoning )  all of which appear to be unable to preform
dig lookups the spamhaus hosts. Is anyone else seeing similar results?

Works for me (I'm running Bind locally to resolve names), though
1.ns.spamhaus.org times out.

I'd suggest flushing the cache or change the resolver/try with a
different resolver.

If you query the spamhaus servers too often, you will be banned.
You have to pay (a considerable amount of money, last time we looked).

Other than that, better ask on the Zimbra forum...
