Henri, that will be exactly your problem. Investigate your DNS setup, even do that Ethereal thing between your DNS forwarder and the RBL. Then you can see if the RBL didn't respond, or your DNS 'lost it'.
DNS timeouts are a killer !!!!!

Hello Rob, You're probably right, it might be a DNS problem... I run dnsmasq (http://thekelleys.org.uk/dnsmasq/doc.html) on my server as a forwarding DNS server. It supports caching though that's useless when querying blacklist services. It seems to be quite fast but I did notice something funny with it. Taken from syslog: (1) query[type=1910] 122.132.43.200.dnsbl.sorbs.net from 127.0.0.1 forwarded 122.132.43.200.dnsbl.sorbs.net to 194.109.104.104 (2) query[A] 1.140.26.83.dnsbl.sorbs.net from 127.0.0.1 forwarded 1.140.26.83.dnsbl.sorbs.net to 194.109.104.104 reply 1.140.26.83.dnsbl.sorbs.net is 127.0.0.10 As you can see, there never came a reply to the first query because that ip address is not listed. It should reply 127.0.0.1 though! The second query did receive a reply, stating that the ip is listed. Maybe that's the problem? I have no idea why dnsmasq won't reply 127.0.0.1 though. Any ideas? -- Henri. - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
