Edit: I was wrong; ignore this response.

According to this page (groupsrv.com) your BIND daemon doesn't understand IPv6.

I do not think this issue is related to understanding IPv6. The link provided mentions clearly about 'AAAA' records. But here the issue is not the same. The log messages pointed out by 'maiijarb' is specific to 'MX' records.

Here what I believe is happening is that the client does a recursive query to the name server. The name server points this query to the external name server for an answer but the external name server responds back with a 'serv fail' or 'query refused'. This will get logged in the logs as an informational message.
