Hi guys, I had a problem earlier today when our local DNS server's forwarding servers were slow to respond.
I had a number of emails from various sources rejected as blocked by zen.spamhaus.org. The IPs I checked weren't on the list according to the spamhaus website. I did notice that doing a "dig @localdns.server zen.spamhaus.org" didn't always return an answer. After changing the forwarding servers in bind the problem seems to have cleared up. Is this the expected behaviour from Postfix if an rbl cannot be reached? Is it possible to have Postfix pass the mail rather than reject if the server cannot find the rbl? Or would that be a bad idea even if it can be done? Thanks Guy -- Don't just do something...sit there!
