Hmmm... well, I have two of them, and they're linked in parallel. If one of
them dies, I'm still OK. A bad automatic software update could take both of
them down, it's true... but that's a risk I am willing to take.

Actually, Exchange server DOES send mail, 24/7. It's covered by my SPF record.
Any recipient server that considers my mail spammy because I don't list an
outgoing mail server as an MX is misconfigured. But I haven't had a problem...
as far as I know.
