One thing you may try is to tune up your DNS server cache(Increase max-cache-size and set cleaning-interval to a value of your choice. Carlos. --- El jue, 4/29/10, Joseph C.

Re: [courier-users] zen.spamhaus.org
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Yeah, it's something on this end. Probably the name server we'd been using is being used by others and it did too many queries.

Re: [courier-users] zen.spamhaus.org
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Howdy again folks, I checked into this a bit more and I found that positive responses for the test system are returned from a machine other than the server I was using. That machine uses a different dns server, so that must be what happened. The recursive name server we've been using obviously did too many combined queries. How irritating.

One easy thing to > test: 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.

I'm still seeing about 8000 messages blocked per day (1600 so far this morning). So it seems to be working fine. -- Bowie -- ___ courier-users mailing list courier-users@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

Hello, Spamhaus is known to block DNS servers who perform too many queries to their DNS servers. If you use your ISP DNS, it could be the issue. One easy thing to test: nslookup .zen.spamhaus.org @ nslookup .zen.spamhaus.org @ For example, Google DNS are blocked. HTH.
