It doesn't matter if you get the results back randomly or not. If you
pick randomly from them, you are guaranteed to still have a random
distribution. If you pick randomly from a non-random set, you have a
random distribution. Therefore, it is irrelevant the order that DNS
gives you the MX records in. Picking one of these at random is the
right thing to do. If someone wants you to give precidence to one of
these hosts, then by definition, that someone must change the MX
precidence to be a lower value.

What possible advantage would you have to using the first one of the
list all the time? I don't get it.
