here, every host (legit or not) will try MX1, then if compliant, will
try MX2. legit systems are thus somewhat penalized.
In GL, once a host has been "automatically whitelisted", it is no more
Also here, a spamware that tries second MX won't be blocked. while in GL
it will be deferred.
so the approaches may be used together. I personally don't feel playing
these MX games.
