There is no evidence of systemic DNS issues with that domain: http://dnsviz.net/d/kpbsd.k12.ak.us/dnssec/ This looks like an issue at the OP's local resolver. Perhaps flushing the cache will help. This assumes there's no dedicated transport for this domain, with its master.cf entry specifying chroot, while other domains use a non-chroot transport. -- Viktor.
