Yes.

MX records point to hostnames, not addresses. It should be:
foo A 1.2.3.4
foo MX 10 foo
foo2 A 1.2.3.4
foo2 MX 10 foo (or foo2, since they're the same)

You're missing the preference values on the MX records (the 10's in my
examples). This syntax error will cause the server to return a
non-authoritative answer.

What's the point of telling us this if you're not going to tell us the
*real* domain?
