Hi guys, we have found a strange behavior of the domain: mydomain.com. This domain receives all the email from the most important mail services but none from gmail.com This email was sent by the server where it has been registered. Code: The mail system <email@example.com>: Host or domain name not found. Name service error for name=mydomain.com type=A: Host not found If I send an email from gmail.com I get this error: Code: *DNS Error: Domain name not found The strange thing is that the mail server receive correctly the email from other mail services like yahoo.com and other. Any idea?
