While I understand Russell's concerns, I think that we should have
a second machine to be able to swap in. If the primary every goes
down, then the secondary must be able to take over, or else we will
have problems with the project. We cannot assume that the MX admin
will be able to fix the problem ASAP.

About backup MX... well, we can put them elsewhere. I run a couple
reliable MXs and could also serve as backup for Debian.
