Hi gang,
A few weeks back I discovered PowerDNS and immediately took a serious liking to it. It required a bit of a study to make it work (for example: it separates the concept of a DNS server with that of a DNS resolver) but now that I got it to work I'm very pleased with it. I even prefer it over Bind/named these days.
However, quite recently something odd began to happen: the server refuses to resolve freebsd.org, as a result several e-mails originating from FreeBSD's website got bounced because Postfix suddenly figured that the domain was invalid.
I noticed that the firewall is related to the problem because as soon as I disable it the domain gets resolved again (note: firewall got briefly disabled, and because the server is behind a filtered connection the risk is minimal), once enabled it eventually breaks.
The weird thing though is that it has no issues resolving other domains. From microsoft.com to linux.org, no issues. But freebsd.org (and also samba.org) are causing problems.
I just noticed that both domains are registered with Gandi so now I'm beginning to wonder if that could be related to my problems. It's weird that only these two "gandi domains" give me an error whereas other domains resolve easily.
Any ideas?
