    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 protected]>: 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?

    Does the A record of your domain exist and point to the correct IP? Do the nameservers that you use in /etc/resolv.conf resolve the domain correctly?

    Hi falko,

    yes the A record point directly to the right web server. In the webserver there is a mail domain with the name of the domain registered.

    Yes, the nameservers resolve correctly the domain.

    Thanks

    intodns shows this warning:
    I'm not sure, but maybe you should lower the expire - maybe this causes the problem.

    Try 3600 instead.
