I do in fact have the ability to change my domain's zone files.

... and there is what you describe (N.B. this from a web form, not
exact zone file syntax) :-

    *                    86400   A
    *   10 mail-in-1.lb.gradwell.net.   86400   MX

So can I simply delete these two entries?  (OK, people mis-typing domain
names *might* be affected but that's mostly me so I don't see a big
issue there)
