Host or domain name not found

I have a little problem with receiving mail from outside to ispconfig server using squirrelmail.

Inicially i configure my ispconfig server with the domain mydomain.pt, but this mistash with the outside domain so i have changed to a local (private) domain: headquarter.mydomain.

I have already changed in ispconfig setting the dns servers and ns's server to, to my new domain.

I have configured another domain anotherdomain.no-ip.info for an client, the problem is when i send a email to (for example) [email protected] i receive the following mail:

Final-Recipient: rfc822; [email protected]
Original-Recipient: rfc822; [email protected]
Action: failed
Status: 5.0.0
Diagnostic-Code: X-Postfix; Host or domain name not found. Name service error
for name=hostname.mydomain.pt type=AAAA: Host not found.

Can anyone give me an help, thanks.

Best Regards

 

Soo no member can help me?

 

Well, without actual domain names or IP addresses this is hard to help. There's so much obfuscation (or it looks like that), your message does not make much sense. The problem is for sure DNS (98% ). Look at the IP address of hostname.mydomain.pt. Does it point to the right IP?

 

martinfst is right. Please check the DNS record with

Code:

dig hostname.mydomain.pt

 

Hi, i have very same problem, "Host or domain name not found. Name service error for name=centrum.cz type=MX: Host not found, try again". DIG command have correct output on server.
