Greylisting suffers from one problem that unplugging the server doesn't:
greylisting usually works on a triple like (IP address, sender,
recipient), and can therefore continue to reject people who do retry,
but retry from a different IP address. This occasionally affects things
like Github notifications and requires manual intervention.
(I would still recommend greylisting, personally, but it's a harder sell
than that of foregoing a secondary MX.)
