This means that some bright soul is listed as authoritative for that zone but
is not serving the zone. In this case, reverse dns for 217.57.19.0/24 ...
Who does 217.57.19.0/24 belong to? APNIC says interbusiness.it - some random
italian ISP.

Hmmm... yet another rocket scientist doing the same thing ... only, for a
domain. At least one of his nameservers is not answering authoritatively for
chequemail.com
suresh@mjollnir 19:14:33 [~]$ host -t ns chequemail.com
chequemail.com name server NS2.DIRECTIHOSTING.com
chequemail.com name server NS6.DIRECTIHOSTING.com
Hmmm... both these nameservers dont seem to be answering at all, let alone
for chequemail.com (network issue between hong kong and india maybe...)

Refuse recursive queries.
options {
directory "/var/named";
// query-source address * port 53;
allow-transfer {
10.0.0.1;
10.0.0.2;
};
recursion no;
fetch-glue no;
datasize 96M;
};
Then for logging - man named.conf ... you will get a lot.

Try asking your ISP? Or better still have you tried "dig your-isp.com NS"?
