Huh?  There doesn't seem to be a MAN-GILL.COM domain registered.  There's a
MANGILL.COM domain, but the DNS server that it's delegated to
(SECONDARY.DNS.IAGNET.NET) doesn't have any information about the domain.

What are these records doing in the man-gill.com.db file?  This file should
only have records for names in the man-gill.com domain.

The new configuration doesn't have any MX records for predict-dli.com.
There's an MX record for mx1.predict-dli.com that points back to itself,
but it doesn't have an A record.  The NS record for the domain points to
ns1.predict-dli.com, which is a CNAME record; NS records should point to A
records.  You need to create an A record that points to 207.206.8.34, so
that your NS record can point to this name.

Since the old configuration works, why don't you just set up the new domain
the same way?

No, this is not how mail is delivered.  If the MX record points to valiant,
mail from the Internet will be sent directly there, it won't go through any
of Verio's servers.
