Well, apologies all around, more or less. 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 <ethic>  cat resolv.conf
What I really think broke things was to have left the AAAA addr rec
in their blindly. :
