Bug detected - some ccTLDs doesn't work

I have detected a bug.

The ccTLD in third level doesn't work, for example the ccTLD ".com.es" of Spain

For example, domains like "domainname.com.es"

I have test it and it is the error message:

Checking DNS Zone Record for Domain: d******.com.es   
Checking Zone File: /var/named/d******.com.es.db

/var/named/d******.com.es.db:4: warning: l********@gmail.com: bad name (check-names)
zone d*****.com.es/IN: loaded serial 2013071600
OK

Please, you have to fix it !!!

how did you added this account/domain ?
