To be fair, I >could easily have a *bad* DNS configuration here. I'm working on that. OK. This is one I can answer. It means that the server said it gave a non-authorative answer, but it lists itself as being able to give an authorative answer. Something like: nslookup -qtyp=any hemi.com Server: foo.bar.org Address: 128.x.x.x Non-authoritative answer: hemi.com internet address = 204.132.158.10 Authoratitive answers can be found from: hemi.com nameserver = foo.bar.org hemi.com nameserver = NS.hemi.com foo.bar.org internet address = 128.x.x.x NS.hemi.com internet address = 204.132.158.10 (actually, I just looked at your DNS entries, and I can see which host you bleeped :-) ) There can be a lot of reasons for this to happen. Best way is to either contact the admin of the server in question and get him to fix his config, or if he's not meant to be a secondary server, stop listing it as an authoritative server. >There were several such entries from different hosts.

It's likely the mail lists, as sendmail verifies the address on the To: and From: lines I think, which causes quite a bit of DNS activity. who.cdrom.com (the nameserver that freefall.FreeBSD.ORG uses) logs a lot of lame delegations as a result of the mail traffic through freefall... Hope this helps Gary
