You'll see a root delegation if recursion is denied. In the example
you gave, look at these flags from the result:

;; flags: qr rd;

qr = query received
rd = recursion desired
ra = recursion available - not present

Since there's no ra flag, the server queried is refusing recursion to
the menandmice.com web server, and so it gives the closest result it
has in cache.

Listen to the folks at pshift.com. They know whereof they speak, at
least in this case.

The "pop", "smtp", and "mail" aliases should point to the appropriate
host(s) in the pshift.com domain. Since 216.114.155.114 isn't
handling mail for this domain, you shouldn't point these aliases at
it.
