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) firstname.lastname@example.org
i receive the following mail:
Final-Recipient: rfc822; email@example.com
Original-Recipient: rfc822; firstname.lastname@example.org
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.
