He's not really using round robin DNS, if he has mx1 *and* mx2 listed with different IP addresses, though they have the same priority. So if one of the servers goes down, any sane mail system (which seems to exclude qmail in this case - no flamwars please) should try the other MX, if the one which had been chosen first is not reachable, as this is seen as a temporary error. Sure, if he had only *one* hostname with two IPs, this could be a problem.
