Well, I already had a backup MX (just in case my ISP turns evil or
something), so it wasn't a big deal to take advantage of that feature.
I wasn't so much worried about email not finding a server; I shut down
port 25 because I didn't want email to find a *misconfigured* server as
I was setting it up. Imagine having your mail server announce that your
user doesn't exist here; fun stuff like that.
