Default How to test my name server & email server

I just want to know how to test my name server and if I have set it up right?
( my dns settings attached)

I have found in a topic to use:
Code:
dig @ns1.dcs-online.nl powerfromhell.com
if I do that I get:
Code:
server1:~# dig @ns1.dcs-online.nl powerfromhell.com
dig: couldn't get address for 'ns1.dcs-online.nl': not found
I can reach powerfromhell.com in my browser guess its still reachable trough the second ns (mydns.org) but that one I want to chance also if all the sites are moved from my local server to the server at the DC.

TIA

You missed the dots at the end of the fully qualified domain names ( in all your CNAME records). In DNS, every FQDN has to end with a dot. Only relative dns Records like "www" do not end with a dot.

What you need is a glue record for ns1.dcs-online.nl which has to be setup in the dns server of the domain registry. Glue records are nescessary in a case where the ns2 is a subdomain of the zone which is the case in your setup (ns1.dcs-online.nl is a subdomain of dcs-online.nl). Thats the "hen <==> egg" problem. To lookup the zone dcs-online.nl one have to know ns1.dcs-online.nl, but ns1.dcs-online.nl is part of this zone, so it can not be looked up. The solution is the glue records, which can be setup in the dns server of the .nl registry.

Till,

Are you refering to an A record of NS1 to Ip address for the domain?

If you have the Nameserver setup to go to ns1.example.com and it follows xxx.xxx.xxx.xxx would you also want to have the an A record of ns1 point to the xxx.xxx.xxx.xxx

Good practice?

I'am talking about glue records, glue records are DNS A-Records, but theiy ahve to be set in the dns server of the registry and not your local DNS server. Please see the links above for a in depth explanation on glue records.

Thanks to your links I have setup the nameserver with the glue record. Hope all has gone well.

One question left the mail server is setup right this way?
So my users just use pop3.dcs-online.nl & smtp.dcs-online.nl?

I guess I will notice in a few hours when the next refresh is completed...

I dont think things are setup as it should be. I can test the name server with dig command.
Code:
server1:~# dig @ns1.dcs-online.nl dcs-online.nl

; <<>> DiG 9.6-ESV-R1 <<>> @ns1.dcs-online.nl dcs-online.nl
; (1 server found)
;; global options: +cmd

server1:~#
server1:~#
But I noticed one warning message in the output.
Also I cant send any email out if I test send with outlook the smtp server works but the pop3 server doesn't

Any help would be very appreciated...

This looks all fine and the warning is ok too.

Regarding the pop3 server issue, please look in the mail log and post the error message(s).

All is working now but I had to make setting I dont want to.
It was only starting to work after I had made the pop3 & webmail zone with my dyndns account.
So I am guessing that my own name server isn't working as it is suppose to do.
