Exclamation DNS Not Resolving Domain Name

Hi all,

I have a freshly installed ISPConfig (installed using the howto for Fedora Core 5) and everything seems to be working fine.

Recently, I installed a site andon this site there is an email form that sends out email enquiries to my clients email accounts. Past week or so, I have been receiving complaints that some of my clients were not receiving anymore enquiries and they tested the form on the site and didn't receive the emails at all.

I've checked the maillog and found the following (domain have been changed) :

Nov 1 09:42:53 fc5-g3 postfix/smtp[12597]: B96334080B8: to=<>, relay=none, delay=7705, status=deferred (Host or domain name not found. Name service error for type=MX: Host not found, try again)
I did nslookup and dig on the domain to find out more

# nslookup -q=any
;; connection timed out; no servers could be reached
Any other queries on other domains gets a response as normal but not this and a few other domains.

Initially I assumed that it was a wrongly configured domain and nothing to do with my server's DNS. However, when I used an online nslookup site, there seem to be no problem. Even doing a lookup on my local Windows machine gives me a response.

Any idea what is going on with this?


I have not done anything apart than what
