MX Record

When I said that a 0-preference would work just as well "in this case", the
"case" I was referring to was a production, Internet-visible mail presence, which
usually doesn't change that often. For test networks, I'd say go with whatever is
easiest to maintain, although I'd still point out that the "traditional" 10, 20
etc. preferences should probably be avoided, since there are more *digits* in those
and therefore more opportunity to make typos, etc...
