Hi

When sending emails to the domain zyxel.co.uk I get delay messages

When I do a NSLookup check on zyxel.co.uk and against zyxel.com I get the following message

Default Server: w2003sbs01.meridian.local
Address: 192.168.16.2:53

> set q=mx
> zyxel.co.uk
Server: w2003sbs01.meridian.local
Address: 192.168.16.2:53

*** w2003sbs01.meridian.local can't find zyxel.co.uk: Server failed

> zyxel.com
Server: w2003sbs01.meridian.local
Address: 192.168.16.2:53

Non-authoritative answer:
zyxel.com MX preference = 10, mail exchanger = mx01.zyxel.com
zyxel.com MX preference = 90, mail exchanger = mail3.zyxel.com

mx01.zyxel.com internet address = 216.237.21.132
mail3.zyxel.com internet address = 66.59.243.66

As you can see I can not resolve zyxel.co.uk on our server

Zyxel.co.uk seems to be resolving to our router 192.168.16.254, how do I resolve this

Thanks
 
Contacted ISP they ran the same test and got correct results
They use same forwarders as us

So I think it must an internal DNS problem but have no idea how to fix it:confused:
 
Tried to flush dns but doesn't resolve the issue

Checked host, and lmhost at C:\WINDOWS\SYSTEM32\DRIVERS\etc

If I ping zyxel.co.uk

It still resolves to our router 192.168.16.254

Can't see where it is getting this from:confused:
 
I've run DNS Flush from server and client machine

I have looked on the servers DNS forward lookup but don't see an entry for zyxel.co.uk


Done on both DNS forwarders
