Outlook only accepts IP configurations


All of a sudden I have stopped receiving emails on my outlook. I pinged my mailserver  and I could get a response back. Decided to run a nslookup and inserted the pertinent IP's on the email configuration page of Outlook. Ever since, it only accepts emails if I use the Ip and not the fqdn, can somebody help me figure out why is that so? I am not a dns expert!!!!

seems that you have a DNS zone (domain.com) in your internal DNS, while your email is somthing@domain.com.

if this is a case then you have to create an A record in that dns zone ( your pop server name (lets say "pop")) and points it to the server ip address.

what nslookup return when you use if from internal:

please post the seresults :

nslookup pop_server Internal_DNS_IP

nslookup pop_server IPS_DNS_Server
try restarting the DNS client service on the outlook computer

can you ping by name ?

Yes I have restarted the computer several times, aside from that, the problem resides within a domain and it happens with every client. I am behind an ISA Server, acting as a web proxy too. Yes, I can ping by name.

Hi Suimanw,

I really thank you for enlightening my mind. I was missing an A record for some reason, I only had a MX record and the A record for the webmail. One last thing, the IP address keeps changing every once in a while, is there anyway for me to avoid having to update the records manually?

Kind regards
