Validate new records not catching some errors for manual edits

[Deepcuts]

Webmin version | 2.302
Virtualmin version | 7.30.4 Pro

I needed to edit DNS records for a domain and by mistake I wrote a , instead of .
The "Validate new records" from Virtualmin/DNS Settings/DNS Records - Manually Edit Records catched nothing.
Strange thing is "named-checkconf /etc/bind/named.conf" also reported nothing.
Because I did not see the , when I checked, I tried Webmin/Servers/Bind DNS Server - Check Bind Config, which promptly showed me the error and I was able to fix it.
Rookie mistake, but then again, my eyesight is not what it used to be.

Can you tell us where the errant , was exactly?

Also, does the command named-checkconf -z /etc/bind/named.conf detect the error?

Errant , was like this:
subdomain,domain.com. IN A 1.2.3.4

named-checkconf -z /etc/bind/named.conf detects the error and shows:
/var/lib/bind/domain.com.hosts:26: subdomain,domain.com: bad owner name (check-names)

named-checkconf /etc/bind/named.conf does not detect the error.

Ok I tested this with the command named-checkzone domain.com /var/lib/bind/domain.com.hosts and surprisingly it reported an error like that as only a warning!
