Does anybody still have their original FC5 config file?  I'm sure I
didn't change mine, but I noticed that it had the accept unresolveable
domains option allowed.  That doesn't seem a sensible default option,
even if it only listened to 127.0.0.1, by default.  Someone might change
the listen address, without checking other settings.
