I'm not entirely sure how, but the conversation that followed this went off-list. For completeness, though, I can declare this matter closed.
After some sterling help from Brian Candler, to whom I owe my grateful thanks, this turned out to be a typo in the DNS file, and nothing to do with PowerDNS at all. Thanks for the help! Cheers, Laurie. _______________________________________________ Pdns-users mailing list Pdns-users@mailman.powerdns.com https://mailman.powerdns.com/mailman/listinfo/pdns-users
