Given the client IP address 127.0.0.1, Postfix gets the name
ip6-localhost, but that name does have the address 127.0.0.1.

And indeed. Name ip6-localhost does not list address 127.0.0.1.
Somewhere, you have a mapping from 127.0.0.1 that returns ip6-localhost,
and that mapping is screwing things up, because 127.0.0.1 is not
listed as an address for ip6-localhost.
