Although there are other things that will prevent a dead circuit to hotmail.com from plugging up the entire queue, it's still better to minimize the degree of pluggage as much as possible.

First off, what's to say the other MX's at the same priority will be down? You're just guessing here and I don't see how you can guess accurately either way.

It wasn't that long ago when all of microsoft.com was DOSsed off the net because they put all of their DNS servers on the same subnet, and the sole router upstream of their got DOSsed into hell.

A little investigation shows that all of their MXes are in just two subnets. Definitely DOSsable.

If all of their servers refuse to accept the mail, then it's their fucking problem.

If you have a huge mail queue as a result of that, affecting all of your mail traffic, it now becomes your problem too.

There's a perfectly valid reason for it and no detriments. I don't see how you can just ignore it for anything less than it's horribly broken

You got it. It's horribly broken.
