Incoming mail problem and LAN connection problem

Richard G said:
Well that is very odd. Because then with a dig -t NS on your domainname, then I should always get the NS records, even if your nameservers are not working or are offline.
And this is not the case at the moment.
I would suggest to contact your domain name registrar and have them kick the nameservers again.

It is very strange. I will try. Thanks for your advice

I think I still need to change something on server conf files
 
Looks to me like DNS issue still playing up. Port 53 missing from port list open above which is important for the nameserver setup and DNS functions of the server, unless you are relying on a 3rd party for your DNS like your domain registrar. Regarding Nameservers, check if there;s a misconfiguration? Post up your DNS record on DA for your main domain that's also used for NS. Check the glue records at the registrar also. Just a note, some (not all) require 2 nameservers minimum WITH 2 unique IP A records, Some registrars you can get away with 1 IP address for the 2 nameservers. Just trying to collab with the other guys here in giving you ideas on what and where to check.
