You have broken the "CNAME and other data" rule. "mail" owns a CNAME record,
therefore it cannot own a record of any other type.

What exactly were you trying to accomplish, anyway, by making "mail" *both* a
CNAME for "bush" *and* an MX record with "bush" as its target?

Of course, the syntax for the MX record is hosed also. You forgot the
preference-value field.
