We had a major DNS failure, after completely rebuilding the DNS servers. I am having issues.

When I click on the "Check MX" button in the admin page I keep getting the dialog box saying the

SMTP host is set to localhost. localhost host was not found in the MX records.

Zimbra pulls up fine, but is not receiveing email.

The A records are set up the same, well ...... obviously not. but the MX records are correct. Accept zmail will not take incomming mail.
