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

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)?


# dig @myprimary.dns.server mx
# dig @mysecondary.dns.server mx
# dig @mythird.dns.server mx
# ..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
