They're all wrong and two of them are useless.
- wrong: MX records have to point to NAMES not ADDRESSES.
- useless: the numbers after the "MX" are the priority. The lowest are tried
  first. Pointing MX records with different prio to the same host is
  useless, as if it isn't reachable with prio 10 it sure isn't also
  with prio 20 or 100.

GLOBALOK is a comment and can mean whatever you want it to.
