I'm aware of that particular limitation. We have been using a DNS server other than the ISP's. However, it is one others have access to, so I suppose that could be the problem. However, I'm not getting an error looking up stuff. It's just everything appears to be returning nxdomain. I tested this using nslookup. In addition, I performed the test spamhaus says to perform in order to test the blacklist functionality. It returned a message to me saying my blacklisting was not working properly. Here is my config line from /etc/courier/esmtpd: BLACKLISTS='-block=zen.spamhaus.org,BLOCK' I haven't changed anything though, so I don't think this would be the problem. Interestingly, there was some kind of networking issue at the site where this server is located, hardware problem. No lookups have returned positive since right around the time that happened. - -- They say god has always been. Linux and I will now disprove that: $ ar m God ar: creating God There you have it.
