    Here's what I have, a near full output. Are all your name servers
    running on dynamic DNS? Could the lookups be coming from a stale DNS
    cache?

    What are the results that you are looking for? What are the results that
    are incorrect? Have you done a dig against all your nameservers to
    ensure they are all accurate? Are you running an MX cluster? Are your
    secondary DNS servers reflecting the same records as the primar(ies)?

    ie:

    # dig @myprimary.dns.server mx mydomain.com
    # dig @mysecondary.dns.server mx mydomain.com
    # dig @mythird.dns.server mx mydomain.com
    # ..3..4...and 5....

    At minimum, we need to know the original (old) IP, and the proper (new)
    IP of your MX records:

    pearl# dig mx nagual.st
