Having upgraded to BIND 8.1.2 to minimise the name server attacks we are
getting a large number of errors showing in the daemon log of the form:

A sample hosts file for one of those domains is :
;
; Data file of hostnames in this zone.

_at_ IN SOA mcb.net. postmaster.MANNET.mcb.net. (
6 ; Serial
14400 ; Refresh - 5 minutes
7200 ; Retry - 1 minute
1209600 ; Expire - 2 weeks;
43200 ) ; Minimum - 12 hours
IN NS mcb.net.
IN NS ns0.bt.net.
;
;
busch.co.uk. IN A 195.10.96.2
localhost IN A 127.0.0.1
"hosts-0" IN CNAME localhost
www IN CNAME busch.co.uk.
busch.co.uk. MX 0 195.10.96.231
busch.co.uk. MX 10 busch.mcb.net.
busch.co.uk. MX 100 mannet.mcb.net.
It is not stopping operation or throwing up other errors but I would like
guidance as to what I have misconfigured.
Thanyou in anticipation.
