[Bug-mailfromd] how are dns lookups done
Hi Sergey,
I know I have 1 buggy dns server. I upgraded a while ago and the new version of dyndb at fedora is crappy compared to how it used to be. So I know this 1 server is not a 100% I think this is the cause of a local domain generating this error (does not happen that often)
mailfromd#1[60656]: 44N7wGAS060655: DKIM: fail (public key not found 12) -@ xxxxxxx
But the host I am running this on is having multiple dns servers configured in /etc/resolv.conf, and others listed there should definitely not have any issues. This makes me wonder about what happens at what failure, is eg a 2nd nameserver listed in resolv.conf tried? Is it possible to configure some sort of dns exception handling, timeouts?
>From the command line I never actually experience issues, mostly I notice something weird in application log on a rare occassion.
