To resolve my DNS problems I just copied over my backup SAVED/db.thought.org to my newer, broken copy, updated the Serail njmber, and restarted things. It was a good lesson that I should NOT have ever dared to mess around with IPv6 ... but I did. And yup, after moving the server everything restarted. And that v6 stuff busted things. [ten mins later with coffee kicking in]:: a question on the nameserver stuff: given that I have only one ISP, how could I have another nameserver? ethic is DNS, mail, and web. I've got two secondary nameservers. One in Dallas, a second in England. I did restart dovecot last night; it didn't help. p0 11:44 [1031] cat resolv.conf domain thought.org nameserver 10.47.0.230 What I really think broke things was to have left the AAAA addr rec in their blindly. : NS ns1.thought.org. @ IN AAAA 2002:d1b4:d5d2:: -- Gary Kline kline@thought.org http://www.thought.org Public Service Unix http://jottings.thought.org http://transfinite.thought.org The 7.79a release of Jottings: http://jottings.thought.org/index.php
